hicrop10 Posted 6 hours ago Share Posted 6 hours ago I have mentioned this before and got some great response.But I’m still lost.First question will be how do I know if my truck is positive or negative ground?Secord question what the hell m I doing wrong.I have provided some diagrams of how I have my truck wired up.When the truck is running or not the whole thing is hot.By that I mean touching my test light against anything it lights up(steering column,frame,oil filter and so forth).Any help would be greatly appreciated.When it is running it runs great.I have a rebuilt generator for it and a new voltage regulator,I don’t want to damage them.

Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago Looks like it is wired for neg ground, but I can't say for sure. Once again, look to the alternator (if there is one) or the voltage regulator for a generator (they are sometimes marked as to polarity). If not marked, and there are no electronics, then chose one polarity and run with it. Neg ground makes the most sense today.

Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago Connect the chosen polarity battery to the frame of the truck. with the rest of the batteries hooked up, go to the regulator, jump the battery terminal (B) on the regulator to the armature (A) for a second or two, and that is it. You have polarized the generator and it should start charging the correct way for the way the batteries are hooked. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76666-need-some-big-help/#findComment-595913 Share on other sites More sharing options...
