Holiday Rambler trailer brakes
Hoping someone can help me with this problem. I have a 2001 holiday rambler ambassador. It has a 5.9 Cummins diesel.
I have found with the engine brake activation the brake lights turn on. As has been mentioned in many posts here this creates problems went towing a heavy trailer. My trailer is 7000 pounds and has electric brakes. If I turn the engine brake on the trailer brakes go to full.
First solution is I have ordered a proportional brake controller which I will install in a few weeks.
However this doesnít solve the overall problem of the brake lights being on whenever the engine brake is on. This is definitely not my preference.
I checked some other threads on this and found references to fuses and relays however could not find anything labeled as they advised. I have taken the switch apart it has eight leads into it and several jumpers, I doubt I will be able to figure out how to disconnect the lights from the switch. And Iím a little nervous about messing with it. I do not want to blow something out of the engine computer.
Anyone solve this problem on this particular coach? If I canít figure it out, and no one can tell me how to do it, I will likely put a momentary switch on the dash which will allow me to disconnect the brake light feed to the trailer brake controller.
Thanks in advance for any advice
