Hello all, and thank you for reading

So this only just started to happen...

Scenario:
I'm driving along and whenever I accelerate pretty hard, the battery light comes on. The harder I stamp the gas pedal, the more brighter & intense the battery light illuminates and will stay on.

As soon as I let off the gas pedal, the light goes out.

Anyone experienced this before?

Hoping it's something like voltage regulator, so I'll test alternator output.

thanks all,
Tiny

Hi Tiny,

I did. One or more diode(s) in my alternator was/were shot. I first suspected the voltage regulator also, changed it against a new one, no change.

Eventually I used my multimeter to check the voltage reaching the alt light from the alt, a whopping 17 volts.

A replacement alt did the trick.

HTH
