farmall h 6 volt cutout switch

Marlin taylor · Feb 18, 2011

I ordered the 6 volt volt cut out switch for the generator, and got a 6 volt regulator. the regulator has 4 connectors, L, BAT, F, and one on the bottom that is not identified. Will this regulator work instead of the cut out switch, and if so, how is it wired?

I don't know who you ordered it from, but from my research, I can tell you that an aftermarket, reproduction cut-out relay for the Farmalls does not exist. No one makes it, so what you got is a 6 volt regulator. The regulator will work, and in fact is better than a cut-out relay.

Here are the wiring digrams. Just sort through them and pick the one that fits your needs.

You can hook it up like Rusty says or you can just use the cut out portion of the regulator and use high and low charge like the original H used with a cutout if you want. If you could get just the cut out similar to the original it will cost as much as the regulator anyway.

Okay, great the regulator is better anyway. So, is the post underneath the regulator the one that connects back to the A post on the generator? Wire the BAT post to the ammeter? Leave the L and F post on the regulator alone, and wire from the generator F post to the light switch???? I have the magneto.

Just check out those diagrams. I know one of them will be exactly what you need for a magneto. Incidently, the magneto is totally independent of the electrical and charging system, and connecting battery voltage to the magneto is a sure fire way to destroy the coil in the mag.

not using the L and F terminals may not allow your regulator to work at all (no charge condition) or it might allow the cut out function of the regulator to work (regulator work as the cutout only). I want to know for sure myself, I theorize the cut out will still work.

Provided the regulator will work as a cutout only, The way you are talking would let the light switch still regulate the field as the cut out system did but as long as you have the regulator, why not use the other features and have the charging rate adjustment fully automatic? For originality purposes go ahead, but for modern convenience I recommend using the regulator in its full capacity.

okay, that makes sense. so how exactly is that wired? i'm guessing run a wire from the "bat" terminal to the neg battery post. then run from the L terminal to the light switch....is that right?
