Steven - All of the ideas below will work, though with a couple of clarifications:

1 - Wire the Hobbs meter "-" terminal to the regulator GEN terminal. (Assumes you have a positive ground system - if your tractor is negative ground connect the Hobbs "+" terminal to the GEN terminal) The meter should run whenever the motor is running, even when the generator is not charging (3 or 4 volts appears at the GEN terminal even at low idle...)

2 - The pressure switch idea will work - though you gotta use a NORMALLY OPEN pressure switch (one that closes it's switch contacts when it senses pressure) for this to work. Note: Nearly all vehicle oil pressure switches are NORMALLY CLOSED - contacts close on loss of oil pressure. So you can't simply grab any old oil pressure switch and have this one work.

3 - Replace the stock magneto kill switch with a DPDT toggle switch. If you wire it correctly, no relay is required.

I personally prefer #3...

In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership, ... [Read Article]
