Elkhart RV brake light diagnosising

[WDW]

In short, having problems blowing fuses on brake light circuit. We've got it narrowed to a scenario where when applying the parking brake while regular brake peddle down it burns the fuse. Why? That's where I need someone good. We've had our RV dealer add some inside outlets for GPS / dash camera and two extra stop lights that can be seen when we're towing our Jeep. They added a charge line for the Jeep .

Funny thing - might be unrelated, but if we turn on four way flashers, Jeep brake lights don't override .... But RV brake lights power up.

We're up by Saginaw, MI looking to cancel our trip to Yellowstone. We can go south to Elkhart or home to Buffalo / Western NY.

Any thoughts?

Been trying to get to Yellowstone for a couple of seasons now. Hate to see somebody else loosing out as well.

No clue what you have going on for lights, but wondering if there are certain lights that should come on only when the combo leading to a blown fuse is used? In other words, do ALL of the lights work when they are supposed to? A set not working may give a hint as to what your malfunction might be.

Does the problem occur with and without the Jeep hooked up? If no problem without the Jeep, safe bet the problem is in the Jeep, or the wiring leading to it.

Baring any success there, my first stop would be at the lights that have been added on the back of the MH. I'd disconnect them completely, right at the point where they were wired into the circuit.

Best of luck...

WDW-

Which fuse is blowing?

Did this occur before the dealer made the modifications?

Did it start right after the modifications, or has it taken a while to show up?

Although for a different coach and year, the attached PDF diagrams probably apply. Ford hasn't changed much about these F-53 chassis circuits from year to year.

so does this vehicle have air brakes and to apply the emergency brake is just a air switch... or does this vehicle have hydraulic brakes and you push a pedal to apply the emergency brake...

We've narrowed down to an issues with the parking brake use. Not using it does not cause an problems. However you need to apply it for the levelers. We came home and it's going to. Ford truck dealer that works on MHs, busses, etc.
