A friend has been restoring a T fire engine, which he has converted to an A frame and block. I assisted in the conversion of the wiring. Started up and ran like a charm. Because of the electrical power demands that he has since added, he has installed a Powermaster alternator and a 12 volt coil. He was told that that these are plug an' play installations, and that he should still be okay with the 6 volt starter.

When starting the engine recently, his foot slipped off the starter pedal twice. The starter evidently locked up, and he had a bear of a job removing the starter from the vehicle. (Locked up on flywheel, perhaps?). My question: is a 6 volt starter compatible with a 12 volt electrical system?
