All of a sudden, all four of my dash gauges appear to be misreading. Fuel gauge reads half tank low, engine temp is cold at operating temp, oil pressure reads higher than normal, and ammeter shows discharge. This happened all of a sudden a few days ago...any ideas how this might occur and what I can do to correct it? Stumped.

Don't know what year your car is, but in the 50s, cars had a "voltage stabilizer" that reduced the voltage to a value below full battery voltage. This allowed the instruments to see a constant voltage regardless of battery condition (unless lower than the "stabilized" voltage.) If the "voltage stabilizer" fails - some of them were mechanical with bimetal heating coils - the gauges get wacky. That could be your problem.

Tested the alternator. It's good. While I was there in there I noticed some melted wires on the wiring harness. Bingo, that must be the problem. Wires shorted and melted a bit. Here's the question now: is it worth cutting splicing new wire or should I bite the bullet and get a whole new wiring harness?

Originally posted by Surfpilot View PostOk will try that, however as I noted in post #5, I found melted wires on the wiring harness, so there's my short right?

Follow up, in case anyone cares: after some head scratching and some more electrical voodoo going on, I was able to isolate and fix the problem. It was the voltage regulator. It had gone bad and was causing a low voltage situation, so everything from engine starts to gauge indications was wacky. New voltage regulator and a charged battery and we're back to normal. Thanks for the help guys

Very Typical, on Studebakers it is almost ALWAYS the simple easy stuff that will "throw you"!
Overthink it and you will just run into a dead end, if you don't believe me just ask Jim Studebaker.StudeRich
