DoBro Jesus Posted December 30, 2015 Share Posted December 30, 2015 Hey bros, long story short, alternator packed up in my telstar, whipped it out, brushes were fucked so jammed some new ones in, everything always worked fine now its charging again with new brushes but power is fluctuating between 14.5 and 15ish volts so when any dash lights or headlights are on it pulses.checked power to reg and theres power there, it could be the reg but just seems odd that it was working perfect before now its playing up. Any ideas? Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 30, 2015 Share Posted December 30, 2015 Sounds like a poor connection somewhere and is most probably related to the work you have done so the first place to start is in the alt. Here's a couple of possibles. Dirty contact patches between the commutator and brushes, clean up with some fine sandpaper and re radius the edges with a ball point pen, they should be bright copper in color and smooth not brown with lines. Check the connections for the brushes to the diode pack, there may be some corrosion. Poor earth for the diode pack. Oil between the mounts and the engine or loose bolts can also cause a bad earth. Damaged wiring or components in the alt, When brushes wear out they can spark quite heavily and damage insulation and internal connections. Could be the reg if it's the old type with points so check them for pits and burnt contacts. Quote Link to comment Share on other sites More sharing options...
