Normally, if no one has butchered the wiring, there will be nothing wrong with the wires or gauges, ect.
It is grounds and connections that corrode or rust over a period of sitting around.
I have spent hours trying to get my fuel gauge to work on the 57. Finally found the problem: The spades on the back of the gauges were not making connection all the time, just at times, making it hard to pinpoint the problem. I removed the nuts and spade connecters, sanded the nuts and spades. Walla! All gauges work perfect now, with no fluctuations.

We had a joke/truth when we were fixing airplanes, " connections, connections, connections" Every time some thing weird would happen it was some sort of bad connection always. Still the hardest thing to teach the new guys and the most frustrating thing to find. But when it works..:)

If you didn't the punishment was intense!

The 2 gauge ones are harder to find, but necessary. | | | | | Joined: Jan 2013 Posts: 603 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 603 | Yep. I have restored a bunch of the old 2 cyl. John Deere tractors. They all came out with 6 volt. You gotta have BIG battery cables on them.
