High Voltage Surge

[CFR__AND_SONS]

Reviving this thread!

My truck is the Limited trim (not sure if it matters) so I've found out that everytime I need parts, they are more expensive than the other trims.

Anyways, I held off on replacing the alternator but it just started raining and sure enough the high voltage came back. I'm 98% sure that my truck takes the other high amp alternator (will double check with dealership) but I dont have TV, fridge, or microwave or anything but a amplifier and subwoofer. Do I HAVE to replace the alternator with the high amp one?

When I started this topic, my voltmeter always read 14.7-14.9. I got it checked and the electric said it was fine even though I really feel like its too high.

I'm hoping that when replaced, the surging will go away.
