Surge in Fan Speed-Lights Get Dim and Bright


New Member
Have a 1990 Wagon that has as intermittent problem with the fan speed surging as well as the headlights (really all lights that are on) getting dim and bright. Just want to verify that this is an alternator problem and not something else. Sometimes the battery light will flicker as well while this is going on. Thanks for your input!

I think you're on the right track.
Get the alternator tested and go from there.

Readings are anywhere from high 14’s to mid 17’s. Seems to be all over the place when it’s acting up. I’ll be replacing the alternator soon. Thanks for the input!
