Hello everyone!
I have a 98 Volvo V70 XC Chassis#505073
I have a curious problem...
I have recently, within the last few weeks, replaced my alternator, serp Belt, idler pulley and tensioner. The battery was also replaced the same day.
Today, my battery light came on. I tested the battery, and alternator, and both tested good.
I also tested the alternator while loaded (lights on, fan on high)
And that tested good.
A curious quirk though, when I bump the throttle, the light goes away. Then it comes back on after a few seconds. Then after some idleing, the light stays off for good.
Aside from a slight rough idle, everything feels fine.
Any ideas?
Replacement Alternator was a Ultima Alternator from O'Reilly's.
Battery light on. New Alt and Batt.

Check the battery cables and B+ line for corrosion. Grounds are importation too.alpha318 wrote: 22 Jun 2020, 22:03 A curious quirk though, when I bump the throttle, the light goes away. Then it comes back on after a few seconds. Then after some idleing, the light stays off for good.

Make sure the exciter wire in the back is clean and non oily
If that’s good, it’s alternator Tetris back to O..o...o....o Reilly’s for anew unit
