I'm trying to get the charging system working on my BN.
It's a mutt, roughly a '46 with a distributor ignition and a
cutout. Not a voltage regulator. 6V, positive ground of course.
Here's what I know - the generator motors and charges.
That ammeter is wired right and works both directions.
The aftermarket cutout that was on it was bad, so I replaced
it with a spare original style 3 wire Delco-Remy one I had.
I have added an additional ground wire from the block to the
generator case. I jumpered that ground wire to the cutout case.
Still a discharge on the ammeter and no increase on a
voltmeter across the terminals of the generator or at the
output of the cutout.
[b:14fdf6c602]It will charge if I ground the field wire.[/b:14fdf6c602]
I have the field wire on the generator connected to the field
resistor on the switch where the wiring diagram says it should
be. Field to ground with it hooked up cold measures 2.5 ohms.
Too high?
It has a 4 position light switch in it, with no dimming resistor.
The resistor may not matter since it has no lights.
Do I need to use a three position switch or did I overlook something else?
