Default RPC pony motor getting hot?

Grant Erwin wrote:
Normally a pony motor is only used to spin up the idler motor, then it
is mechanically disconnected and shut off. This is often done by a
hinge/belt/lever arrangement, whereby the user tilts the pony motor away
from the idler motor until it's almost far enough, then slips on the V
belt, then tilts the pony motor away a bit farther until the belt is
tight, then, holding tension, switches on the pony motor with his free
hand, then switches on the idler motor, then switches off the pony motor
then relaxes the lever and lets the belt flop off. I had never heard of
keeping it electrically powered throughout. I'd just try reconfiguring
your converter a little so you can shut off the pony motor.


His pony motor is NOT electrically powered after the spin-up, at least
that's what he says. It is mechanically connected so it keeps spinning
when the RPC is on. But, that shouldn't make it get hot.
