Mike Fratello Posted March 23, 2016 Share Posted March 23, 2016 Have not yet started my B61 which was transported from Pa. My question is per the build sheet it is a 12 volt system??? Can I run 2 12 volt battery's instead of 4 6 volt battery's?? Thanks Mike Quote Link to comment https://www.bigmacktrucks.com/topic/44427-b61-1957/ Share on other sites More sharing options...
HeavyGunner Posted March 23, 2016 Share Posted March 23, 2016 Don't see why not. Just hook the batteries up properly so you don't end up with 24 volts. 1 Quote The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living.The government can only "give" someone what they first take from another.

hicrop10 Posted March 23, 2016 Share Posted March 23, 2016 Yes, you can run 2 12 volts instead of 4 6volts.One thing you should know your truck may start on 24volts and run on 12volts.You should look under the passenger seat and see if there is a spw this will tell you if it start on 24 and runs on 12.Good Luck. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/44427-b61-1957/#findComment-328209 Share on other sites More sharing options...
Mike Fratello Posted March 23, 2016 Author Share Posted March 23, 2016 I read about the spw it is under the seat with a box covering it what does it actually do?.

41chevy Posted March 23, 2016 Share Posted March 23, 2016 It a switch that allows the truck to start with 24 volts and with the key in run position runs the normal systems (lights etc) on 12 volts. 4 Battery cables from batteries and 2 small gauge wires from starter switch and amp meter. Here is the basic B model wiring schematic link. http://www.bigmacktrucks.com/MusicVid/wiring_diagram.pdf 1 Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/44427-b61-1957/#findComment-328212 Share on other sites More sharing options...
