Hello Everyone,
My name is Colin Livingston and I live in Darrington, Wa. I recently just started working at a sand and gravel company working on their Mack trucks and their trailers. They have three Mack CXN613's (years 2005-2007) and two Mack CV713's (years 2007 and 2008). Friday I was told that one of the Vision's (CXN613) has a problem where the stop lights don't work on the truck or trailer. I have tried jumping the stop light switch, looked at all the fuses that I know about, and swapped out the relays for good ones all to no avail. My question is is where are the ground or grounds located? Also does anyone know where to find a wiring diagram for the stop light circuit? Thanks in advance for any clues of where the problem could be
