[QUOTE="redbloke1956, post: 46413, member: 2299"] Thanks for the reply mate, Yeah OK that makes sense, but on gens, motors and alternators the patina is the grey/black film created by the carbon/graphite in the brushes and is essential for brush life and efficient operation, on all machines I have worked on if the patina was disturbed or removed (by skimming in lathe) we spent considerable time bedding the brushes and ensuring an even patina before putting them back into service. So while I agree about the miniscule voltage drop experienced in the magneto I am not so sure about the lubrication aspect as I have seen many brushes wear out rapidly due to not spending the time to produce the initial patina.........Now as I have said this all applies to the slip rings and commutators in motors and gens but I still don't see why the same wouldn't apply to a mag........thoughts??
