Re: [Chevelle-List] Stereo question.
Hey Herb, I don't think a cap will prohibit this "thump" sound from happening. My understanding of a cap is that it "stores" power so that when you hit a deep bass note, it'll hit with full force or power. You're obviously getting enough power to make this "thump" sound so you shouldn't need more power from a reserve storage of power. If anything that'll make the "thump" sound stronger. The cap is usually for a problem like your when your headlights dim at night when deep bass notes are played. The normal power from the battery runs the headlights (and everything else) at a consistent power level and then the deep bass note uses the normal power plus whatever reserve power is stored in the cap. To stop this "thump" you have I think you're looking for something like this http://www.sounddomain.com/sku/STISPSON Rodney. 71 Chevelle El Mirage, AZ - Original Message - From: Herbert Lumpp To: Chevelle List Sent: Saturday, October 05, 2002 5:09 PM Subject: [Chevelle-List] Stereo question.

RE: [Chevelle-List] Clock/Gas Guage Checkout
Donnie, check out my page at http://johnnasta.com/6898/clockrepair You can run it off the car battery, but you will need at least one wire since the terminals will not just conveniently reach each other.

Re: [Chevelle-List] Clock/Gas Guage Checkout
Donnie to check clock all you need is a car battery 12V and a small wire. There is a small terminal on the back side of the clock that you touch to positive and just rest the metal bracket that would be screwed to the instrument cluster to negative. The gas gauge has positve feed all the time( when car is on) and the sending unit in the tank sends a negative feed to the gauge. The amount of fuel changes the amount of resistance in the negative feed. There should be 2 terminals on the back of the gauge. I don't know if it can take a full 12 Volts across the terminals. You also have to be carefull with polarity, you don't want to send it hard in the wrong direction. JUST WHAT I HAVE LEARNED IT COULD BE WRONG. Any other ideas out there!!!

[Chevelle-List] How to figure out if a guage works or not???
Maybe this one slipped throught the cracks, or maybe I stumped the list I just purchased a used bezel for my '67. How can i check to make sure the clock and gas guage work correctly without using my existing wiring from my car and before installation? I would actually like to see the clock move and also the fuel guage..how would you guys do it? I believe you can also use an ohm meter??? what should it read?? Thanks Donnie

RE: [Chevelle-List] Stereo question.
Title: Message Herb, I am not an electrical engineer. I was only a technician. But I had to know most of the theory. Still it's been years so I could be wrong on this and somebody please correct me if I am wrong. First, since the alternator feeds back to the battery to keep it charged, they are electrically the same point no matter where you take your power from .unless you have resistance losses from smaller diameter wire or long distance wires or other things in the circuit (such as terminals with corroded connections) that don't allow the full potential to be felt at that point (- resistance). The alternator is the one feeding the electricity to circuits needing it or your battery would go dead. You always want to make sure that your wires can handle the current being drawn though. A 6 gauge wire should do the job. It could very well be that the relays are chattering when switching. If that's the case, might have to research a fix. It could also be that the alternator switching on is causing a spike as you suspect that will effect some sensitive electronics. You are on the right track in thinking capacitor. A capacitor is a voltage device it filters voltage fluctuations, and it won't pass DC current, so it has to be from the positive line to the ground. A choke (coil) smoothes out fluctuations in current. A fairly good filter design is a choke and a capacitor working together. One of the more common designs for electrical filtering is a capacitor with a choke then another capacitor. That's called a Pi filter due to it looking like the Pi symbol. I haven't look at Radio Shack lately but they may have something like that already to install. I say go for the voltage/current filter first, then troubleshoot the relays. They may not be hefty enough to handle the load. They may need some filtering that the filter would solve.

Re: [Chevelle-List] Fuel gauge part 2
John, I pretty sure it's a different tank. After looking at it I can see where the filler neck has been cut and has a rubber extention on it and it is off set by about 2 inches. You would think that the stock tank would line up and not be off set. When I burn this tank of fuel I am going to remove the sender and try to bend the arm to match the old one. If that doesn't work I'll just drill a hole through the bed into the tank and use a stick. LOL Thats everyone for your help.
