I can’t see how much is left of these brushes.there seems to be some left.
a multimeter between their terminals reads 3.6 ohms. does that sound ok.
if not I’ll just replace them.
2 wires from the sensor at the end of the commutator reads 180 ohms ?
grateful for any advice. Thanks
sounds about right but you cant check brushes accuratly with a multimeter. take them off and look at the end touching the commutator. if its shiny its making contact. if its dull its arcing
look at the length anything under half an inch is getting low
