Next Problem..........

Goose · May 6, 2019

I have an H Farmall that has a bigtime drain on the battery. It will give a pretty good spark when you hook up the battery cable.

The lights are gone off of it, and I recently replaced the ignition switch for a different problem, so the only thing I can think of doing it is the voltage regulator somehow doing it.

Is that possible? It's the regulator mounted on the generator. Unless I can think of something else, I'll change the regulator and rewire it in the process. With no lights, there's not much to the wiring. I can build a new harness cheaper than I can buy one.

Why not unhook some wires, one at a time, and find out exactly where the drain is?

I'll do that. Haven't had time, yet.

I wasn't sure why I had a small drain on my boat's battery, so I stuck a knife switch on the battery. Under 10 bucks as I recall.

good chance the cut out relay contacts in the regulator are stuck closed

For the price of another regulator you can get a small alternator with built in regulator and have improved performance and greater reliability

It should be simple to rewire.

Not on a tractor but on a car, a1948 Oldsmolile that was driven at most ince a week for short distance. Every time wanted to start dead battery Finly found the problem, the metal end of battery cable was just close enough to something else (think it was probably starter but 50 years ago) but and we had looked at that connection dozens of times trying to find problem. It was on back side and not easily seen but it turned out that even tho not actually touching was close enough current was flowing all the time over that paper thick gap, bent the cable end to get more clearance ant took care of problem. Was a slight burnt spot when we took cable off and that is how we found it.
