my son accidentally shorted out the positive battery cable to ground ,and now the gauges don't work ,unless the headlights are on , and even then after a couple hours they will stop. all fuses are good. It's like it's backfeeding through the cluster. Then a couple months later ,the truck wouldn't start , but tried to off of wd-40. Tried it later on , and it lit right off. I'm suspecting the PCM.
2003 sterling truck mercedes engine, gauges inop , unless headlights are on
