Matt- do you have a multimeter?

If so, is your roboteq wired up with the red and black mains wires (the thickest ones) going into an Anderson? I guess so...

If that's right, unplug it, set the multimeter to dc volts and check the supply voltage to the roboteq as a start. ( check the side of the plug that goes to the rest of the wiring.... Not the half connected to the roboteq.

With the link in it should read around 24v. If not your problems easy to solve.
