Voltage Regulator
 

Occasionally my charging system acts up and starts to overcharge,
when it happens it lasts for about 30 seconds then goes back to normal.

I assume I'm having a regulator issue, I have good grounding from the regulator
to the engine block and body.

Should I try the Blue Mopar regulator PN I saw in the sticky
or try the internal regulator conversion in the sticky?

The alternator is a reman unit put on two years ago and the
regulator is a std replacement from Chrysler.

Any thoughts?

I had this problem recently, turns out it was a loose negative battery cable! I'd check as many grounds as possible, but it could be that voltage regulator as well, although I believe the internal ones are more prone to failure than the external ones.

If it comes to it, go with the external, its such a easy hookup. Autozone has them for around $15

yeah but i bought about 3 from autozone and all of them let it overcharge, and blew my headlights. i ended up going to the scrap yard and grabbed about 5 OE ones for 5 bucks a piece. they work like a champ.

i went to napa and gave them a picture of what i needed they gave me one for a ford i believe it works great 14.6 volts at the battery.

it doesnt have to be for our trucks, most any reg close to the same year will work.
