Re: Four Little Motors
This sounds familiar. I'll guess that you are using PWMs to command the speed controls, correct?
It is possible to drive a couple speed controls via PWM w/o powering the DSC. But, once you get more than a couple PWMs going out of the DSC w/o powering it, you begin to have trouble.
Make sure you have +12vdc going the the DSC from the PDB. Then also verify that you have 3 green lights lit up on the DSC. That should do it.
