hicrop10 Posted 2 hours ago Author Share Posted 2 hours ago I’m wiring up the truck now. Using 2 12 volt batteries,not 4 6 volts ones.Here’s the diagram I’m using,is this correct?I am pretty sure the truck is positive ground.Anything I should be doing since it has been about 15 years since I last wired up a Mack. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73175-mack-b873sx-restoration/page/12/#findComment-592430 Share on other sites More sharing options...
mechohaulic Posted 1 hour ago Share Posted 1 hour ago that diagram should do you just fine since only change you are making is the 2 -12's VS 4-6's. difference in dia with 4 -6's would have two 6 volt batteries tied in series on each side. 6's in series = a strong 12 also give a longer lasting cranking power. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73175-mack-b873sx-restoration/page/12/#findComment-592433 Share on other sites More sharing options...
