Ahrfox1745 Posted June 23, 2014 Share Posted June 23, 2014 My voltage gauge on my 1987 Mack CF 600 was working fine while driving . I drafted / pumped at a show, then while driving home, the gauge was below ten / stopped working. Any ideas? Thanks. Quote Link to comment Share on other sites More sharing options...
j hancock Posted June 23, 2014 Share Posted June 23, 2014 1. The gauge may be broken. Could run some leads to a know electrical source and see what happens.2. Alt. is dying and your are running off of battery reserve. Take a multi meter and see what the output is off the alt.3. Check health of batteries and for loose connections/corrosion while you are messing with everything. 1 Quote JimIt doesn't cost anything to pay attention.
