So my 89 started making a buzz sound with key on engine off.
With the old hose to the ear sound detector trick, I traced it to the alt.
Now, I got a back up alt. and unhooked the suspect unit and hooked up other alt. (on top of valve cover not installed).
Turned the key on and when alt. case is grounded I can hear the buzzing on the back up alt.
Whats going on? Has it been buzzing the same way for the last 25 years and I just never noticed?
She's putting out proper volts --14.4 about
Anyone been through this?
