Driving home on Sunday with the van in tow,happen to look down at the Prodigy2 Brake Controller and it was Flashing with the display reading N.C. I checked when I got home the Trouble shooting chart says .1 Trailer connected with open circit on brake line ,2 Trailer connector disconnected or corroded,3 loss of Trailer break magnet ground, I proceeded to have a look under the van this morning and guess what a broken Magnet Wire on one of 4wheels, wich I repaired I haven't tested the van again yet ,the question is would that be my problem? Hoping it is.
I have had the same n.c. lit on my vehicle brake controller as well, but I found by wriggling the trailer plug the fault went away. I put my problem down to a bad connection on the van/car plugs. I have since replaced the plug and it hasn't happened again. It looks like any bad or missing connection in the van brake circuit might cause the fault.
The prodigy 2 is a great controller. Remember though that you can get a nc message which starts the heart to flutter but can be as simple as the plug connection not being right. A simple fix with a small knife to widen the pin will most probably solve the problem.. Has happened to me before.
Cheers
