Harmonyards, the engine is regularly run and the roller p/ups were replaced about a year ago. I removed both motors to check that ground and hot /p/up connections were properly insulating. Grease is fresh. Its not a mechanical binding issue but thanks.
Gunner, thanks I am going to measure the draw at the rectifier later today. Not sure where the triac is on the board but will try to check that as well. Is there a way I can test it with a multimeter?
Thank you
Ralph
