[AT] Generator wiring question

[Easley, Greg]

Thanks Cecil - This one is going to be used strictly on the pulling track.
It would be nice for the charging system to work.  I think I'll put a SPST
toggle switch on the dash for manual control of the field circuit.

        On tractors with cut-outs, the Field wire normally connected
to the light switch. The terminal it connected  to took the circuit
to ground thru a low ohmage resistor - approx 2.5 ohms or so - and
this gave a charge rate of somewhere under 10 amps. Pulling out on the
light switch turned on the lights and took the Field circuit straight
to ground. This is what is called "full fielding the generator". The
third position on the light switch on some tractors did the same thing
without turning on the lights in case you wanted to hit the battery
with a heavy charge rate. It would not be advisable to charge at full
charge all the time as it could damage the battery. If it were mine, and
the tractor had lights, I would be tempted to wire it the right way -
thru the light switch to ground when the switch was pulled out. If you don't
have any lights on the tractor and just use the starter occasionally,
I suppose you could just leave the wire off the Field post on the generator
and use a jumper wire when you want to charge the battery by clipping one
end to the Field and the other to ground. Charge the battery for a half
hour or so and then take the jumper off.
