Over charging battery
Hi, Iv'e got a1969 F600, dump truck, with a 361 heavy duty motor.
I put a new alternator and voltage regulator in, and I'm still getting over 17 volts to the battery when running.
Doesanyone have any suggestions on what I can check next?
Thanks,John

some of the old regulators had to be polarized, i cant remember which posts you do that with but it could be as simple as that. some of the old timers on here might know how to do it. no harm meant by the old timers thing as im 42 myself.

Thanks, I did a search on the topic after I started the thread, ( alittle backwards), and I read about a good ground. I'm going to run a new ground to the regulator and see if that helps.
Thanks for the replies, John

Do not discount a bad (shorted) cell in the battery, that can make the voltage regulator run high.

It took me awhile to get around to doing it, but I ran a new wire from the neg on bat to the regulator and that solved it. It was charging at 17-19 and now it's down to 13-14.
