Mini Alternater Noise


Post by laipappy » Sun Mar 13, 2011 4:07 am

Im running a used mini alternator on my 58 pan. It seems to keep the battery charged, but it makes a loud whining noise while cruising but not at idle. From where I sit its louder than the exhaust. It is bolted to the cases with no gasket at all. Could it be the unit or was my installation bad? Thanks for your input!

Sounds like bearings?

Check in the "Knowledge Base", in the Electrical heading, there is a thread on the noise these units make.
