jcoll55 Posted August 7, 2009 Share Posted August 7, 2009 Hi I have a 1955 B42 model Mack I am starting to restore. When I bought it. It came with no battery. I looked at the generator to see if it said what the volts were, it did not. So I pulled out a head light and it's a 6 volt light. But the wiring goes through a resitor before the light so it might be lowering the volts. the Battery box is small, only big enough for one battery, And It's hard to believe that one 6 volt battery could not only start a big gas engine but run the whole truck too. I hope some one might know what the deal is thanks. Quote Link to comment Share on other sites More sharing options...
