Topic: Ignition voltage


Hillfarmer    -- 05-09-2021 @ 4:21 PM
  I just purchased a 1940 Deluxe. It quit after about 40 miles driving it home.

I suspect two possibilities. One a defective ignition coil or a defective ignition resistor. However, I don't know if the old 6 volt systems used a resistor on the ignition.

The starter relay does not have a terminal for a 'high voltage' circuit during cranking.

After cooling for a bit the engine started and drove two miles home. Then died and would not start again until it cooled.

  There is a resistor under the instrument panel. However, that's rarely an issue.
From your description of the failure, you are most likely experiencing a faulty coil and / or a faulty condenser.
Save yourself a lot of frustration and send a FORD coil to George Haney for rebuilding. He's the best at this and is prompt and reasonable. Seems to me he's around $75 for this... money well spent.
