Ok , so how many have had a break controller go bad? Backround, my TT breaks show low power when driving at like 25 mph. In park , reads a ok. For the last 2 weeks, ive tested wires, looked for bad conections, replaced and cleaned all grounds on the TV and TT. Tested the alternator and battery. Ran addotional ground straps, checked continiuity of wires , etc. I can not find any thing wrong, last ditch effort is i ordered a new break controller. ( test on break controller while parked checked out ok.) If this dose not solve the problem, i will re wire the breakes in the TT. ( they work just under 25 mph). I cant find much on break controllers gone bad, just people saying they sometimes do. Any thoughts or advice or just a hang in there. Lol. Was looking at new TV the other day, I've about had it. I cant even narrow the problem to the TV or the camper at this point. The trailor was just taken to have the breakes and electeical to the breaks checked.
