Curt,
Never seen the alternator on a motorcycle, but a stator should be a stator.
It's just a stationary winding, connected to the battery (via a
rectifier/diode in your case), that has current induced in it by the
magnetic field produced by the energized (via brushes) rotor. Bad, short,

Wilton, similar symptoms years ago on a 300SD. Crawled under looking for
brake band adjustment screw, and a slow fluid leak led me to right to it,
where I found a (factory-intentional headless) adjustment screw, coupled

Sounds like bad connections at, wiring to, or dirty internal contacts in the
thumbwheel thermostat, which was, last I checked, a replaceable part of the
PBU. I don't remember buying the part at the time, and successfully
repairing the ACC, so it must have cleaned up satisfactorily. As to blower

dry. Pull the motor and see if it runs. But first, try another 12V source
to run the motor with, preferably one that doesn't get bent in a door

I'd bet on plugged fuel filter, air leak at one of the supply hose
connections, or an algae-clogged fuel tank strainer. crack the fuel filler
cap and listen for a whoosh.
