1940 LaSalle Won't Charge

[jwaldrich]

Freshly rebuilt generator and new voltage regulator on my 1940 LaSalle. The regulator and generator were bench tested as a pair and put out 7.8 volts on the test bench but nothing in the car.

I am out of ideas. All worked fine previously but failure caused me to pursue rebuiling the generator. That didn't fix the problem so inslatlled a new regulator. Hours and hours chasing wires and still no joy.

Could use some help.

Hate to be Captain Obvious, but have you checked your battery out? Sometimes it's the simplest of things.

Ditto, have you polarized your generator?

Ditto, ditto, have you checked to see that your ground connection at the regulator is good and clean?

Ditto, ditto, ditto, have you checked and double checked that everything is wired up correctly and the wires themselves in good shape?

That's pretty much the only things that could be wrong if your generator and regulator are in tip top shape as you say.

I had a similar problem when i first started driving my 37, it was a misdirected wire,it was charging but the juice was not going to the battery,i forget exactly what wire it was,but once they were switched it was fine.I think it was the ammeter wires were backwards?,you should be ble to follow the current,see where it stops,that should be your problem,use a wire tester or volt meter,should be pretty easy to tell. harveyb

If there is a condenser attached to the generator for radio noise suppression, make sure it is not attached to the field terminal.
