When I put it back in I had no power to anything. After removing and installing it several times it started to work. Today I removed it to replace the voltage limiter and now I have no power again. The red wire has voltage and the black wire shows voltage so the amp gauge is good. The assemble is grounded to the dash by the 4 screws that hold it in place. There are only the black and red wires to the amp gauge and the plug that plugs into the gauge assemble and the plug to the ignition switch. Everything is wired and the plugs are in place. The unit is grounded so what else do I check? I have no power to start the car or headlights or power at all. Any ideas? thanks

Might want to make sure you are getting power into the cab then try to find out where it is or isn't going. Kinda sounds like the fuseable link. It's a heavy (red?) wire coming out of the bulk head connector into the engine compartment. It will have a yellow tag that says fuseable link if still stock. If this goes you will have no power. Might have shorted something putting the gauge cluster in and out a lot. I have mechanical Aptitude. I can screw up anything.

Everything (almost) is hot so be careful what you bump/touch. What I do is take off a batt cable & put an inline fuse holder in series w a 20 amp fuse for protection (& a tin of 5 fuses) live every 24 hour block of time like it's your last day on earth

I hate to have this be a Christmas distraction for you having family and all and I am certainly willing to go out of my way and help a fellow Moparter out. I hear it's beautiful country down there . What Andrewh said the black wire from the ammeter to the firewall bulkhead out to the alt it splits before it hits the bulkhead & T's to the fuse box the headlights and the ign sw so there's a splice in the harness right behind the dash instrument cluster. Might pull the dash again! (you could prob do it blindfolded w all the practice you've had) & unwrap/check that splice live every 24 hour block of time like it's your last day on earth

I've been underneath removing rust and painting. I have the rust under control up to the where the floor pans will have to be patched or replaced. I really need to remove the entire dash and start cleaning the rust from that area. I was waiting till I had the windshield removed to start that but it may be a good time. There has to be a short in the circuit being this happened last time I had it out. Come on down to North Carolina, it is a beautiful place to live. After being in 46 states while working, I have found beautiful places in every place I have been. You may have to look harder in some than others, but its still there. The nice part of where I live in the piedmont is I am 3 hours from the ocean and 2 hours from the mountains. Hope you have a Merry Christmas. Now I have to go bake cookies and roll peanut butter balls. Thats what happens when your wife works and you stay at home. That means the car has to wait till after the weekend. talk to you soon. have a great day.

Yes what Andrewh said if the ammeter has full continuity I'd unwrap that T esp if everything is dead but w more thought I just cant see the T loosing continuity to all 3 so yes start at the ammeter cause the red into it has fire correct? live every 24 hour block of time like it's your last day on earth

Its strange that when this happens I have no lights or anything else. The ignition switch is dead, but I will find it. I think I have another wiring harness if I had to change that I could. Not one of those projects I wanted to do, but if it would solve this than maybe I should. There is no power at the fuse box, I think you had ask me earlier.

Not one of those projects I wanted to do, but if it would solve this than maybe I should. Actually a wire the thickness of a strand of hair will still show 12V potential but no significant flow can go thru that small of an opening but you'd think with 12v on the downstream of the ammeter that that is not the prob but I'm surprised all 3 component that are fired from the T are dead. None of them are showing any potential (~12V on the VOM)/are 100% dead live every 24 hour block of time like it's your last day on earth

The T is just a soldered connection wrapped in the black electrical tape on the main loom just behind the dash. I could perform an exorcism (which has to be done in person) then take it for a cross country jaunt (west) just to confirm it's healed. I'm pricing a bus ticket as we speak. Your baking cookies ,no wonder you have a happy family, save me some EDIT make up a long jumper wire with alligator clips on each end (you'll use it many times in the future) & jump from the batt positive post to the downstream lug on the ammeter and check the batt large negative cable also if any doubt about it's continuity. lets get the ammeter out of the way Last edited by RapidRobert; 12/21/11 01:19 PM. live every 24 hour block of time like it's your last day on earth

Santa quickly said no. Santa is not real fond of my gold fish. I informed her when I was finished and went to my first car show she wasn't allowed to ride with me, She said she didn't want to, she would follow me in her Jaguar to make sure I made it home. That's cold, don't you think?
