power surge??

[tigertank]

every once inawhile ill get a surge the alt gauge goes from green all way to red at highest point, and if the fan is on its will blow harder. then it will just quit and go back to normal. is this a voltage issue??

Your alternator is bad probably. Just had the exact issue and fried everything in my truck by continuing to drive it. Lights, alternator, starting box... all toast. I would check that and not drive it so you don't end up with a more expensive fix than just a alternator

Old style fan controller box is also known to give trouble. Is the epoxy gooey and melted on it?

Same thing was happening to mine. I have the 60 amp alternator and just replaced the voltage regulator board in the back of the alternator and it fixed the problem.

Save yourself a bunch of money and headaches. Put a delco on it.

Whets the delco part# for reference

I installed a 21si single wire 24v. I ordered it online/with a 2 groove 7/8 bore pulley. You will have to do a little fab work ,but nothing hard. It wont overvolt and fry your electronics. 74m35a2 sells them also-- he's a member.
