Electric Trailer Brake Question
I am new to RVs and recently took possession of a new Montana 3790RD fifth wheel RV. The 3790RD is rated at 13K pounds dry and the CAT scales gave me a trailer axle weight of just under 11,000 pounds....

I really appreciate the information you've provided. It blows my mind that the Chrysler engineers are having any difficulty at all in understanding the problem here as it's a really basic circuit. I think the big issue is how they came to the conclusion that an arbitrary duty cycle of 60 to 70 percent is mind blowing. If they can't figure out how this will affect the overall current flow through the brake solenoids they shouldn't be employed.
As for the dealers, I've found they don't have mechanics that understand theory, or can troubleshoot anymore. They rely heavily on test equipment, onboard computers, and factory troubleshooting tree's. The days when we invested in training and educating folks as to how it works so they could solve the tougher problems seem to have passed.
Boshog, Let me know if you need any data collected from a second source. I've got a portable scope, albeit a somewhat cheap one. I also have a clamp on DC ammeter etc. and a lot of experience in the troubleshooting and repair of simple control circuits like this, albeit from an aviation rather than automotive background.
