Hello all, let me start with I am no electrical expert but I have been reading here to try and troubleshoot my issue. I have a 1973 Scamp with a V8 swap. Initially, all my gauges worked except my fuel gauge and oil dummy light. I had to replace the tank (car had been sitting a long time and my fuel lines kept plugging up) so I ordered a new sending unit while I was replacing the tank. The old sending unit was rusted in place and the float was gone (nowhere in the tank) anyway. I installed the tank and sender (hooked up the ground wire) and the gauge still did not work. I read on the forum that it could be the in dash voltage limiter so I took the cluster out, took everything apart, cleaned it, repainted what needed it and installed a new limiter. The old limiter was very hard to get out and the new one barely stayed in. I proceeded to bend the prongs outward a little bit to add some tension. The new limiter also had a tab off of it for possibly a ground wire but my old one did not so I did nothing with this. I replaced all the light bulbs while I was at it and reinstalled the cluster. The oil dummy light now works, however, the lights, fuel and now the temperature gauge do not work, ugh. It should be noted that before I did this the ammeter would read really high and so I replaced the underhood VR and that issue appeared to be fixed so I do not think that this was the issue (unless it fried my fuel gauge) because everything else worked before and after I replaced it. I am not sure if the in dash limiter I bought is junk (even though it was $60) or if there is something else I should be checking. If it is the limiter, is there somewhere to get a better one (i got the other one at Oreillys)? I was hoping to save money by trouble shooting the factory stuff rather than going aftermarket but now im wondering if it would have been worth it. Thanks for the input!
