I think the real intent was not so much installing a second motor, but actually
powering the PF motor, or even a second PF motor from the 9V rail. Using the 9V
truck to pick up power from the track and using the 8886 extension wire to
convert the connection and supply power to the PF motor. I am hoping one of our
engineering inclined AFOL(s) will either determine that this can’t work based on
some violation of EE principals or they are inspired to accept the challenge and
show us how this can work. I have a few motors that are candidates for such an
experiment.
We ran three windmills off a 9V transformer at the B & O Show without a problem.
Both of my windmills based on the VESTAS contained PF motors. I am not sure
about Bob’s windmill, but the three were connected to the 9V transformer and ran
without a problem.

| (...) The "new 8866 motor" is just the same motor as found in 9v RC trains that have been out for a year or so. It SHOULD be capable of being powered as you suggest, 9v jumper wire to a 9v track powered motor (but I haven't tried so no promises). I (...) (15 years ago, 13-Jun-09, to lugnet.trains, FTX)
