Sorry, I should have been more clear. I was attempting to create a
copy of the 6 hole plug (only 5 holes are hot for a 300D) hoping the X
would indicate the Pin coming out of the connector. Each X should
have a number 1 to 5 next to it. Each of those 5 posts had an
electrical value that I was testing.
Hope that makes sense?

All the plugs seem to be good. So what was that series of number that
you sent that had the Xs in it? copy below
Plug that connects to the GP Relay
0.0 to 0.1 X
0.0 X X 0.3 - 0.4
0.1 X X 0.3 - 0.4 (where 'X'
equals a plug for 12v from the relay to the GP.)
Can't really figure out what you mean here. If you could do one number
and X per line with a carriage return or Enter push after each X it
might be a bit easier to read. Something like this
0.0 to 0.1 X
0.0 X
0.3 to 0.4 X
0.1 X
0.3 to 0.4 X
Don't know if that is what you wanted to show but this way each of the
plugs is listed on it's own line.
If the values are correct then #2 seems to show a direct to ground
path. #1 may have a ground and #4 may or may not. My Fluke shows .4 to
1.0 for good plugs and I consider bad ones are 2.0 or more.
The worst part is that your other email where you touch the probes to
the glow plugs directly show different values.
Why?
Did you disconnect the wires to the relay from the plugs before you
did those measurements or did you just remove the intake manifold?
Like the others say when you change the conditions of the test then
you don't know where the problem was any more.

OK, I finally tested the Ohms at each installed Glow Plug . I think
the red probe was on the threaded tip each time and the black probe
was on the manifold. 1 - .6 (on the wire hold down nut)
1 - .6 (probe on the 12v wire hold down nut)
2 - .2
3 - .1
4 - .1
5 - .4

Thanks. I plan to toss them all. At least now I know what the
test indicated. ;-)
Thx again

Subject: Re: [MBZ] HELP!! My '91 300D is Not Starting
OK, I tested my old GPs using my DMM and found the following. I put
the red probe against the threads at the tip and the black probe
against
the threads that contact with the head. I used a Fluke 77 Series III
if that matters. And the dial set to Resistance ?.
What does this tell me?
*GP 1 - **0.3 * *Bosch*
*GP 2 - 0.3 "*
*GP 3 - 3.50 "*
*GP 4 - 63.4 "*
*GP 5 - 11.61 "*
*Thanks.
