florinauto Posted December 11, 2013 Author Share Posted December 11, 2013 It must be negative-there's nothing hot there or running to anything hot. Note: this truck was at another shop where they hooked up all 4 of the batteries backwards. We fixed the starter and gauges and the engine starts now, but we have no diagrams to refer to.
