voltmeter surging
I've got a 93 Cummins that surges when I start it. I know its supposed to do this when its cold out, but its 55 here. Anyways it goes like this: When I start the truck and turn the lights on the volts crank up and then there is an audible "click", at which point the lights dim and the voltmeter goes back down to say 8. It does this a few times and eventually stops surging but the voltmeter is pinned up at 14. Any suggestions? I have had a external voltage regulator put in a few years back because the truck was doing the same thing. Could it be a faulty voltage reg? Thanks fellas.

Im having the same problem with my truck
volt meter goes to 18v and it pins and the lights in the truck get super bright, sometimes like that for 5 10 15 min. Measured the volts at the batt when it happen, 17.6 ish volts to the batt.
If the grid heaters are not hooked up will it still cycle or can i unplug this temp sensor and see if it stops?
