The generator on my C-85 is dead (according to a local shop). Unfortunately,
our shop used to be helpful in pointing out the problem, but has now
succumbed to liability fears. We don't know if it's the brushes or the
armature. We'll try replacing the brushes first.

first, verify that the brushes are in good spring contact
w/commutater; that all commutater segments are in place & no burnt
segments. Next, remove belt. disconnect field wire(s) & connect to gen
housing. Apply 6v or 12v (as appropriate for gen) to the output
(armature) lead or connection. If generator motors in same direction
as it normally operates, then it will generate (& you have
successfully restored residual magnetism to armature).

To isolate (& elimanate the voltage reg), reinstall belt, hook up
armature (big lead to regulator) normally but leave field(s) grounded
to generator (and engine and airframe). Fire up & put voltmeter across
battery. As you speed up RPM you should 7-8+ volts (6v sys); 14.5 or
better (12v sys).

If this passes test then we will talk about adjusting regulator after
you reinstall field(s) normally.

good luck & watch out for the prop!!


Does any one know a good place for ordering replacement parts or a rebuilt
replacement? Any helpful tips or suggestions would be appreciated.
