brian1925tourer Posted December 10, 2007 Share Posted December 10, 2007 cooked the starter/genny in my 25, had been rebuilt new brushes, and working fine. then suddenly the wires on armature where they solder into commutator melted, of course motor kept running chewing the insides out. what might have caused this?

nearchoclatetown Posted December 10, 2007 Share Posted December 10, 2007 REBUILT by who? Someone familiar with DBs I hope. Your cutout {voltage regulator} may have stuck. Link to comment Share on other sites More sharing options...
brian1925tourer Posted December 10, 2007 Author Share Posted December 10, 2007 local auto electrician,machined armature on lathe , replaced brushes and front bearing. bench tested ok.not sure what amps were set at. worked fine for about 5 hrs use. you think maybe cutout is faulty,and that would be the cause, there's not much inside genny to go wrong.

nearchoclatetown Posted December 10, 2007 Share Posted December 10, 2007 I'm just guessing, but you had to have a dead short to burn up the s/g, so unless you had a battery cable shift and short out I would suspect the cutout. Can you disect the s/g to see if a brush came loose and short out? BTW, there is a s/g on DBay right now. I bought one from Roy Brister several years ago when mine wouldn't start, only generated. I'm well pleases with it. Link to comment Share on other sites More sharing options...
brian1925tourer Posted December 11, 2007 Author Share Posted December 11, 2007 i have some bits and pieces here to make another, but i used all my best in the first one. where the brushes run looks ok but the wires from the armature have been flapping about and the wire casing has shredded into fluff. checked starter switch and contacts look like they may have stuck sometime but are not stuck now. slight burning there on faces, no other damage.never noticed any smoke either. maybe if can get a photo on here you might see something i can't.

Rusty_OToole Posted December 13, 2007 Share Posted December 13, 2007 The armature can be rewound better than new. They have better wiring now, especially better insulation. Link to comment Share on other sites More sharing options...

brian1925tourer Posted December 17, 2007 Author Share Posted December 17, 2007 you maybe right, possibly has been machined before and with the wear it could have become pretty thin. have machined a spare and ready to put back in, this one measures up a bit more than the other so may make a difference. bit thicker where brushes run too. found out i can also get new commutator fitted. just purchased reco starter switch, old on outside but new on inside.
