1998 Volvo C70 - weak electrical power
 

hey guys,

I had recently bought a 1998 Volvo C70 coupe 2.3L. The lights were always flickering since I bought it. Over the past month, everytime I accelerated or turned on my headlights or AC/heat on full, all the lights would go off for a second and then the radio and everything would come back on.

The voltage readings were also weak 12.8V with everything on. So I decided to replace the alternator. I bought a Bosch 100Amp re manufactured.

After replacing it, the problem still exists. The output is only 12.75Amps. Any suggestions on what I can check? and RSPI thanks for the alternator change video!

I'd suggest this fix, good luck!

Thank you! I shall get back to you latest by this weekend regarding if I have any success. I also intend on bench testing my old alternator at Advance Auto in the mean time.

Cactuslegs - it worked! In addition, I even cleaned out all the engine grounds. Get 14.14V with engine on and everything off and 13.7V with AC and headlights, seat heats etc on.

thank you!

Awesome, glad to hear your success!
