Charteroak Posted March 13, 2018 Share Posted March 13, 2018 I'm loosing electrical power to the cab while driving, then the truck will not start, after a while the cab power will light up, the starter will turn over then every thing goes dead again, i checked and cleaned all the ground wires from the batteries to the cab replaced the ignition relay, Quote Link to comment https://www.bigmacktrucks.com/topic/52795-96-mr-loosing-electrical-power-to-cab/ Share on other sites More sharing options...

70mackMB Posted March 13, 2018 Share Posted March 13, 2018 Take a set of automotive battery jumper cables, using only one cable. Go from the frame to the cab to check for a bad ground. I drove an Ottawa yard tractor with an air ride cab. All most every time you backed under a trailer, the cab would squat down and lose ground thru the cab hinges. We installed a large ground cable near the cab hinges and it solved the problem. .....Hippy Quote Link to comment https://www.bigmacktrucks.com/topic/52795-96-mr-loosing-electrical-power-to-cab/#findComment-394068 Share on other sites More sharing options...
