Starter problems!

[jcf-1968]

I have a 1948 Pilothouse B1C. The resto was started by a man who passed. He changed it from 6 volt to 12 volt. (6 Volt Starter) The problem i'm having is when i push the pedal in to start the engine it doesn't kick over. The engine is free i can turn it by hand. it just seems to not be getting enough juice? Or is it binding? Any guesses?

If you are pushing in the starter pedal and the starter motor does not turn, then try going under the hood and push the starter motor button switch (not the lever) by hand to see if the motor will turn without the starter pinion engaging the engine flywheel. If the motor still does not turn or turns slowly or intermittently, then the problem is either in the starter button switch (misadjusted or corroded contacts) or the starter ground circuit is at fault.

If the starter motor turns fine when the starter pinion does not engage the engine flywheel, but the motor bogs down or does not turn when the pinion does engage the flywheel, then 1) the battery might be too weak, 2) the battery ground may be faulty, or 3) the starter motor may be weak from worn, dirty or corroded internal parts. The starter is not sealed, so moisture can condense on brushes, stators, etc., attracting dust, etc. and ultimately boosting the starter system resistance. That's when it's time enjoy the removal of the starter and getting it serviced

^^^Good advice.

The only thing I know about electrical problems is check the ground!

i did the starter motor switch and it does run. when i do use the lever and engage it with the ring gear it bogs down and doesn't turn engine at all. i have brand new battery and new 6 volt cables.
