Thank you all, for all your help. I found it. I was checking to make sure my 
turn signal dash bulbs were seated and I noticed the screw between the bulbs, 
going through the p.c. panel was not screwed all the way in. I tightened it, 
turned on my lights and the turn signal lights did not light up. Problem 
solved. Again, Thank you all. Bob

Well I got my dash back together with new temp and fuel guages and everything 
is working, and it looks great. Now when I turn on my lights, my turn signal 
lights in the dash light up. When I turn on my turnsignals they blink, they are 
working, However I'am pretty sure the the dash bulbs should not light up whith 
the rest of the dash lights. Any body have an idea on what might be the cause.

I will suggest again that ground is critical. Your fuel sending unit should 
have its own ground wire. The temp sending unit is hot, internally the switch 
closes to ground. With the key to “on” both should be hot. Your fuse box should 
have one fuse marked “gauges” if it is hot on both sides. Then it is a ground 
issue or short in the gauge harness.

I would suggest disconnecting the tan fuel sender feed wire at the fuel tank. 
Turn the key to RUN position and wait a few moments (some gauges are slow) with 
the tan wire disconnected the fuel gauge should read past full. Then ground the 
tan wire anywhere to the body and the gauge should read empty. If you get no

At this point before I would buy new gages I would split the dash harness 
between the cluster plug and fuse box and check for melted or shorted wires.   
Also I would recheck all grounds to cluster and maybe run a direct ground from 
the battery to the cluster, straight wire. 



With the sending unit plugs disconnected and then shorted to ground you should 
have some type of movement in the gage. 



If there were a short or open in the harness nothing would change by removing 
the plugs from the senders.

If you have voltage on the tan wire and you ground the tan wire and the gauge 
doesn’t go to empty you have a bad gauge. The fuel gauge is nothing more than 
an ohm meter and the sending unit is a 90 ohm variable resistor. If you want to 
make sure, ground the sending unit side of the gauge right at the dash that 
will eliminate the wiring to the sending unit and the gauge should go to empty. 
 I doubt if it has a wiring problem because you have voltage at the tan wire. 
You can also substitute an ohm meter for the fuel gauge to test the sending 
unit and wiring 0 ohms will be empty  90 ohms will be full. I hope this helps, 
I have seen some good technicians confused by fuel gauge problems so you are 
not alone.

Leo as you suggested I ran a ground wire directly from the battery to the 
cluster. I disconnected the sending unit wire from the guage in the trunk and 
grounded it. I then made sure I had voltage at the guage with the key in the 
run position. I checked continuity from the cluster to the fire wall. And I 
still didn't get any movement from the guage. I'm not so sure Iam ready to cut 
my  harness open yet. Are you sure I should do that. Everything in the dash has 
power when it's supposed to. Thank you once again. Bob

At this point before I would buy new gages I would split the dash harness 
between the cluster plug and fuse box and check for melted or shorted wires.  
Also I would recheck all grounds to cluster and maybe run a direct ground from 
the battery to the cluster, straight wire. 



With the sending unit plugs disconnected and then shorted to ground you should 
have some type of movement in the gage. 



If there were a short or open in the harness nothing would change by removing

I will suggest again that ground is critical. Your fuel sending unit should 
have its own ground wire. The temp sending unit is hot, internally the switch 
closes to ground. With the key to “on” both should be hot. Your fuse box should 
have one fuse marked “gauges” if it is hot on both sides. Then it is a ground 
issue or short in the gauge harness.

Turn the key to RUN position and wait a few moments (some gauges are slow) with 
the tan wire disconnected the fuel gauge should read past full. Then ground the 
tan wire anywhere to the body and the gauge should read empty. If you get no

Bob, Jim is right. With the cluster plug connected to the cluster and Ign 
switch in run, you should have 12v when you disconnect the plug at either the 
temp sender or fuel sender. If you don’t, then there is an open somewhere 
between the gauge fuse and the sender plugs. 

You can use a test light and disconnect the sender plugs and connect the test 
light to these connectors. The light should light but it will be dim. 



As for grounding; 

You should ground the engine to the frame and to the body. 

You should ground the body to the frame. 

The cluster should be grounded to the dash frame. 

The headlight should be grounded to the cluster by a shorting strap. 

The fuel tank should be grounded to the frame. 



All of these grounds need to be in place to eliminate any grounding loops. Bad 
grounds will give bad readings and can cause you to go around in circles. 



You did indicate that your gauges never did work. My 70 El Camino had a problem 
that was caused by the amp meter wires had melted in the dash harness.   There 
was no indication of a problem except that the amp didn’t move. The outside of 
the harness looked good.   I found the problem when install a TPI engine and 
rewired the harness for the computer and upgrade for glass fuse to ATO. Several 
of the wires were melted together.   These old original harness are in bad 
shape. 



Do check the grounds.

Re: [Chevelle-list] wiring question

Just a few questions. Can you start the engine? Are you sure the gauges are 
wired correctly? 

 

I understand your confusion, just went through this myself. 

 

I will start with the temp gauge. The sender is screwed into your block, head 
or manifold. This contact grounds the sending unit. The ground is not complete 
until it gets hot when a bimetal contact expands inside the sender. The wire to 
the sender goes to the back of the gauge. The other wire on the gauge goes to 
the fuse block and is hot in the “on” mode. In a stock GM harness several hot 
leads come together and are simply twisted and soldiered in a bunch with tape 
wrapped around it. If you have a test light check both sides of the fuse with 
the key on and off. If the light goes on and off at the fuse box using the key 
repeat the test at the back of the gauge. If the light fails at the back of the 
gauge try using a jumper wire straight from the fuse box. If this fails run a 
wire to the sending unit. If this fails replace sending unit.

 

The secret is start where you know you have power test each link until you lose 
the power then back track.

 

The sender has a float like the one in your toilet. As it goes up and down the 
resistance changes. Under the carpet is a flat harness that has a connector 
under the dash and under the back seat. The tan wire can be tested at both 
locations, these do not usually fail. So if you have power at the gas tank 
sending unit skip, testing those connections.  

 

The fuel gauge sender has one tan wire (hot) and one black ground. Check the 
tan wire with the test light. Turn the key to “on’ before you get under the 
car. If it is hot at the sender I would make sure the ground wire is good. The 
test light ground wire should be clipped on the sender where the normal ground 
wire is attached and the probe inserted into the connector on the tan wire this 
way you test your ground. If it fails move the ground of the test light to some 
part of the body. If it works then I would replace the end of the ground wire 
and clean all the rust around the screw hole in the body. One trip under the 
car is enough. 

 

If all this does not help I would suspect that you have wired the gauges 
incorrectly.

have its own ground wire. The temp sending unit is hot, internally the switch 
closes to ground. With the key to “on” both should be hot. Your fuse box should 
have one fuse marked “gauges” if it is hot on both sides. Then it is a ground

What you need to do now is with ign in run, go to the senders unplug them and 
check for voltage at the plug. Either with a voltmeter or test light. This is 
checking continuity from the gauges to the sender’s plugs.  If you have 
continuity then there is a grounding issue.

If you have no voltage at the unplugged sender plugs then there is open wire to 
the gauges.

Below is a copy of the 12 pin plugs for both gauges  idiot lights.

 

With the key in the RUN position you should have 12v at pin 7, the pink wire.

 

Pin 10, green wire, is temp from engine, no power.

 

Pin 11, brown wire is from gas tank sender, no power.

 

Pin 6, Blue wire is for oil pressure light, no power.

 

If you have power at pin 7, reconnect the plug to instrument cluster, with ign 
switch in the RUN position, disconnect the temp connector for the sender and 
ground it. The temp gauge to indicate full deflection. The same indication with 
the fuel wire grounded.

 

The only time you should have power to the instruments is in the run position.

 

I sure hope that this is helpful.

Bob, Jim is right. With the cluster plug connected to the cluster and Ign 
switch in run, you should have 12v when you disconnect the plug at either the 
temp sender or fuel sender. If you don’t, then there is an open somewhere 
between the gauge fuse and the sender plugs.

You can use a test light and disconnect the sender plugs and connect the test 
light to these connectors. The light should light but it will be dim.

 

As for grounding;

You should ground the engine to the frame and to the body.

You should ground the body to the frame.

The cluster should be grounded to the dash frame.

The headlight should be grounded to the cluster by a shorting strap.

The fuel tank should be grounded to the frame.

 

All of these grounds need to be in place to eliminate any grounding loops. Bad 
grounds will give bad readings and can cause you to go around in circles.

 

You did indicate that your gauges never did work. My 70 El Camino had a problem 
that was caused by the amp meter wires had melted in the dash harness.  There 
was no indication of a problem except that the amp didn’t move. The outside of 
the harness looked good.  I found the problem when install a TPI engine and 
rewired the harness for the computer and upgrade for glass fuse to ATO. Several 
of the wires were melted together.  These old original harness are in bad shape.

 

Do check the grounds.

I have voltage to everything except these two guages. I unplugged the 12 pin 
connector that plugs into the pcb and checked  for voltage there. everything is 
hot with the exception of temp and fuel. all my fuses are good. Any 
ideas.Thanks, Bob

  I would suggest disconnecting the tan fuel sender feed wire at the fuel tank. 
Turn the key to RUN position and wait a few moments (some gauges are slow) with 
the tan wire disconnected the fuel gauge should read past full. Then ground the 
tan wire anywhere to the body and the gauge should read empty. If you get no 
response then you have a bad gauge or a wiring problem.

  If you want to check the gauges, send 12 volts directly to them and see if 
the needle moves.  If the needle moves, the gauges is good and there are wiring 
issues elsewhere.  I’ve seen brand new sending units fail.  There should be 12 
volts at the bulkhead connector with the key in the run position for all wiring 
to the gauges.

I had a hell of a time with the dash in my 70. Must have pulled it out and put 
it back in 6 times. Make sure that you have the three black ground wires hooked 
up. One goes to a screw on the cluster, one to the metal frame of the dash 
carrier and one to the e-brake. Also did you put the ground strap back in under 
the light switch?

 

My problem turned out to be the headlight switch. Power to the cluster passes 
through this switch. One of the spades slipped out aside the connector and was 
not making contact. Here is the topic on chevelles.com. It has some great pics 
and information to diagnose the headlight switch. It also includes information 
on the 12 pin connector and tests to verify voltage at the fusebox.

Thanks, Dan. Should I have a voltage at each pin on the 12 pin connector.ie.the 
fuel, temp, and amp. My lights are working, I didn't put a ground on the guage 
cluster itself. can that go on any screw on the back of the cluster. All the 
screws on the back go through the pcb.

I had a hell of a time with the dash in my 70. Must have pulled it out and put 
it back in 6 times. Make sure that you have the three black ground wires hooked 
up. One goes to a screw on the cluster, one to the metal frame of the dash 
carrier and one to the e-brake. Also did you put the ground strap back in under 
the light switch? 
  
My problem turned out to be the headlight switch. Power to the cluster passes 
through this switch. One of the spades slipped out aside the connector and was 
not making contact. Here is the topic on chevelles.com. It has some great pics 
and information to diagnose the headlight switch. It also includes information 
on the 12 pin connector and tests to verify voltage at the fusebox.

wiring issues elsewhere.  I've seen brand new sending units fail.  There
should be 12 volts at the bulkhead connector with the key in the run
position for all wiring to the gauges.

The sending. unit is grounded to the body, and the temp sending unit is new.
Tom,do you know if there would or should be voltage at the 12 point
connection into the pcb. for the temp and fuel guages

Is the fuel sending unit grounded to the body?  If the temp gauge isn't
working, it's usually a problem with the sending unit screwed into the head.

I'am a firm beliver that there is no such thing as a dumb question. My dash
lights are working fine. the dimmer switch is working I just dont have a

Forgive me if it's a dumb question...did you try rotating the knob?  I don't
know if 1970 had the dimmer built into the headlight switch perhaps it's
turned down to the lowest setting or the rheostat is burnt out?

Second, did you check for power at the fuse?

Yes I do have a schematic. I have a 70 ss with guages. Iam just not sure why
the guages are not working.

Do you have a wiring schematic -or- would it help if you had one?  What year
Chevelle do you have?

Dan, The guages are not new nor is the engine harness or the dash harness.
And no the guages did not work before. I was hoping that putting a new pcb.
in would get them working. All the wiring is still original to the car. I
did put voltage to the gas guage when I had it on the bench and was able to
get movement. I used a 9 volt battery and the guage moved to around 1/2
tank. I then reversed the polarity and the guage went back to E. So with
that said I kinda assumed the guages were o k. I really appriciate your
efforts, Keep pitching maby eventually I'll get a hit. Thanks Bob

Are the gauges new? How about the dash harness and the engine harness? Did
the gauges work before you made your changes? The reason I ask is that the
pins are in different locations at the firewall. If one harness is from a 70
and one from a 71-72 that may cause your problem.

Thanks, Dan

Dan, I did ground the cluster with one of the screws that attach the metal
to the plastic housing. And all my lights are working, dash lights, head
lights, but none of my guages are working. Fuel, temp, or amp. All of my
fuses are good. Any ideas. Thanks Bob

I don't remember if all of the wires in the connector

Re: [Chevelle-list] wiring question

I would suggest disconnecting the tan fuel sender feed wire at the fuel tank. 
Turn the key to RUN position and wait a few moments (some gauges are slow) with 
the tan wire disconnected the fuel gauge should read past full. Then ground the 
tan wire anywhere to the body and the gauge should read empty. If you get no 
response then you have a bad gauge or a wiring problem.
