CDR Ham-M Controller Wiring for Series 3 Rotor Rotator

This is mainly for my own reference, since different people wire these differently the colors may not match your rotor. It may be that mine is still wired as they came from the factory in 1974, I don’t know. Viewing the manual and checking resistances is the best way to figure this out if you haven’t a clue where your 8 wires are supposed to go.

1. heavy black wire (gnd)
2. heavy red wire (+26v)
3. sm black wire (+21v / direction pot)
4. sm green wire (motor fwd)
5. sm orange wire (motor rev)
6. sm red wire (motor rev)
7. sm white wire (gnd / direction pot)
8. sm blue wire (motor fwd)

Manual available at:

I also blew the meter fuse while working on this, so I strongly recommend using the manual to test the resistances on your own controller before applying power if you’re reading this.
