truck wiring (Prodigy brake controller)
my trailer brake (prodigy) lights up with 0.00 when I step on the brakes. I can't find a break in the line anywhere so is there a fuse I am missing. Just wondering if anyone else has seen this problem. I have checked my wiring diagram three times, uninstalled and reinstalled the unit. The only thing I can think of is that the brake signal is cut either befor or after the prodigy unit. Any ideas on where to check next. thanks

Just to make it clear, is it doing this with a trailer connected and the tandem vehicles in motion?
Does the Prodigy display show anything when you operate the manual lever with the tandem vehicles at a stop?

Hehe simple answer: you have the power set to zero 
Use the roller-**** on the left to turn it up. Swing the lever underneith all the way and gradually turn up the power until you have enough power to slow the rig when you are driving 10-20mph.

Have you checked the pin connectors in your plug to make sure your getting good contact? Also check to make sure you're properly grounded. You can check your plug output with a simple voltmeter. If all is good there it's probably a connection or ground issue.
