I rebuilt the heater motor several years ago.B  This fall, it stopped
working.B  Taking it apart tonight (Man, I LOVE a garage!), I found
corrision.B  Not debilitating, but nasty nonetheless.B 



Now, I'm going down the road of sanding the copper parts and this time putting
dialetric on them to keep the rust from coming back insofar as possible.B  And
I'm going to replace the brush springs and coat them with dialectric to keep
them from softening with corrosion over the years too.



But just for curiosity's sake, ISTR that electrical contact cleaner is not a
good idea for these old motors, as it eats the whatchmacallit stuff that holds
the wiring together?B  Is there a spray that might work on these old things
that can make the corrosion deposits a bit easier to clean up?B 



Doubt it, but thought to ask.B  This, despite the fact that that my wife
thinks men do not ask directions....
