superdog405 Posted March 25, 2011 Share Posted March 25, 2011 1995 CL 700 e7 454 with v mac 1, engine just shuts down once or twice a day. starts right back up with no problem. electronic malfunction light comes on, but all power stays to dash. Local mack dealer repinned the plug at the pump but this did not fix it. Any ideas would be a big help.

smorse54 Posted April 10, 2011 Share Posted April 10, 2011 hI,with some of our first CH models with V Mack 1 we had problems with the wiring harness where it went behind the windshield washer bottle. The wires would rub bare and short out. This is the harness that goes from the cab to the pump harness.Just a thought, might want to check. thanks, Steve Quote Link to comment https://www.bigmacktrucks.com/topic/18473-e7-454-with-v-mac-1-shuts-down/#findComment-75884 Share on other sites More sharing options...
