When Alternator Goes Bad

MA70-3.0GT · 11-26-2009, 02:13 PM

Still waiting on mine to go, 135k & nearly 20 years!!! (has stood at least 4 too).

Guess it's not as healthy as it could be but still charging, just...

EDIT-: I shouldn't have posted here, I knew it!!! So literally the day after making this post as I'm driving the car the 2.5 miles or so home after collecting it, I switch the blower on to clear the screen & the car nearly dies till I (rapidly!) switched the blower off again, get home & the previously freshly charged battery is at 8.76 volts... lucky me.

EDIT #2-: so while the engine's in bits for the HG job I stripped the back off the alternator & the slip rings aren't too bad, brushes were dead though. I've just cleaned up the contact surfaces & stretched the springs for now to see if it works when she's all back together. If it does then I'll try to find a brushbox for the right money before spending out on a recon.
