Brake Controller Issues

Hello, Glad to have found iRV2. I am having Prodigy brake controller issues. Started with an nc then intermittent 5H. Found the breakaway pin out, and unit melted, also the wires insulation also had been melted. pin.Didn't get any voltage from the trailer connector output pin. Can't find anyone who will let me connect to their trailer. Any suggestions other than to take it to a dealer. WHY the post say I posted this @2:20am BY THE WAY HAPPY FOURTH !!!

Use Voltmeter and check for 12V between pin1 (ground) and pin 2 (brake) when MANUAL Lever on Prodigy is full on. No 12V output then you will need to locate 'trailer brake' fuse on tow vehicle and check if blown (look in tow vehicle manual for fuse location....should be in engine compartment)

Replace Emergency Brake Away and redo the Blue Wiring to/from it

Prodigy Error Codes
n.c. ----Not connected/connected but OPEN circuit
SH ----Brake wire sees SHORT

I'm a bit confused about the mention of the breakaway pin when you say you don't have access to a trailer to try. The breakaway is on the trailer side and not part of the 7-pin trailer connector. Were you connected to a trailer previously and the breakaway burned out? That shouldn't harm the Prodigy, but a melted breakaway and wiring will cause the Prodigy to see connection errors on that trailer.

If your own trailer has the melted breakaway, have you fixed the damaged breakaway switch and wiring? That is basically a direct wiring of the trailer brakes to the trailer battery and could trigger a variety of faults.
