for the brake resistance - MEASURE it with a mutimeter :)
and yes you're right, i meant to say two 12v bulbs in series.

found teh info on motor
http://www.cncwright.com/E690.html (looks like it
might be 120vac motor w/24vdc safety brake)
but nothing on the solenoid resistance - left a msg w/electrocraft support.
as for the bulbs in series, i assume you meant "two identical 12v bulbs in
series" otherwise i'm confused.
can't help wondering if bypassing the controller & driving with 120ac/24dc
might be better/slimmer especially if building more for motorized lighting
trusses.
ty for teh info

wow, you have done well.
the answer is that it detects the missing wheel because it can't
see its BRAKE electromagnet.
the solution is to connect a resistor to the place where the
other motors' brake coil would connect. it should be a resistor
of a similar value to the brake coil on the motor you do have,
or maybe more ohms so it uses less power when it gets energized.
a lightbulb might work, but it will see 24VDC when energized, so
it would need to be a 24v bulb or two identical 24v bulbs in
series.
as for the anderson connectors on the motor controller, please
don't cut them or mess them up - if you need to connect to them
(for example to connect to the brake contacts for the missing
motor) there should be other anderson terminals in the basket
where the motor was. Thanks for not hacking up the wires on the
motors controller.
and congratulations, you're close! once it works, we can use
the other electronics (this is from an old robot) to automate
the process of sending the screen up and down.

Hey all, I'm trying to build a winch for the 14'
projection screen that going up over the ballroom
stage out of a wheelchair motor assembly. Per Jake's
suggestion,
I hacked 2 server PSUs to get 24v@14a but the
controller is not working and the error code says
the right wheel/motor is missing/not engaged. Anyone
know what I am
missing? Do I need to jump something to get the
controller to engage while it is "incomplete"?
Thank you,
