Question:
I have a P3 2012 that wont even power up. Just got a different camper. It worked on the previous camper which it worked fine a couple weeks before. I tested the devise input and there was power. Yet the devise doesn’t power up with or with out the camper connected. Any ideas? Butch

Hey Butch, since you're getting power to the device and it still won't power on, that would tell me that the brake controller itself is defective and would need to be replaced.
Since you already have all the Tekonsha wiring in place, I'd just replace it with the exact same thing # 90195.
I know it's not an ideal situation, but if you have anything else I can help you with please feel free to drop a comment and let me know.
