doesnt change hot or cold. you really have to listen to hear it,but
you can feel it if you touch any part of the engine.lucas

found the problem.. it was in the alternator. the rear shaft part
of the armature was worn an 1/8 inch so it was loose in the bearing
race. the armature was scraping on the feild winding,,still working but
scraping. was going to put brgs in till i got it apart,rebuilt alt
time..gee... lucas
