Hello

I connected the field to a 24 volt source, and I have
pack of 72 volts. But the car takes off, fine, but
then I'll stop, and it won't go up an incline.

Either I'm not exciting the field enough, or perhaps
the field shouldn't be turned off. I have connected it
to a relay on the microswitch on the PB-6...so maybe
that should on the fan relay. That turns on with the
key switch.

I'm also concerned about the curtis controller getting
too hot...of course, that won't be a problem next
month.

Mike, I turn my field winding relay on with the car's
keyswitch, the field stays on until I turn off the
keyswitch. This way, I know the field is at full
magnetic force before ever applying voltage to the
armature. Try it like that, and you should get much
better results. If your inclines are extreme, you
might need to increase to 36vdc on the field, but in
my particular case, 24vdc is enough torque to get over
anything that I've come across so far.
