Bigdogtrucker Posted April 16, 2012 Share Posted April 16, 2012 My B-75 was charging last fall,but after sitting over the winter it's not at this time.It's been converted to negative dround,and the generator was rebuilt a cpl. years ago.What should i look at first to find the problem?

other dog Posted April 16, 2012 Share Posted April 16, 2012 I would take the cover off the voltage regulator first, the points might be stuck from sitting.

fauthpk Posted April 16, 2012 Share Posted April 16, 2012 Also, clean all ground points to the frame. Quote Link to comment https://www.bigmacktrucks.com/topic/24542-truck-not-charging/#findComment-114637 Share on other sites More sharing options...
randyp Posted April 16, 2012 Share Posted April 16, 2012 I take the back generator cover off mine, spray lectra clean in it, blow it out, and while its running, hold a stick of commutator cleaner on it and clean rust off commutator. It usually perks up and goes to charging. Also check all other stuff they mentioned above. randyp (the cover I mentioned above is to the brushes) Quote Link to comment https://www.bigmacktrucks.com/topic/24542-truck-not-charging/#findComment-114645 Share on other sites More sharing options...
Bigdogtrucker Posted April 16, 2012 Author Share Posted April 16, 2012 I pulled the cover and poked around a bit...After that the guage was moving in the charge direction when the RPM's are up.Also noticed my generator belts are a bit loose,and squeal some when reved.How should the points in these regulators be adjusted?Here's a pic of the inside.
