Title: Need Help 99 U270 Popping brake lite breaker
Post by: Green99 on April 04, 2019, 06:42:55 pm
I just noticed when I apply the brakes it is popping the brake light circuit breaker.  I am looking for most likely place to look.  Does anyone know where the plug is located near the rear, so maybe I can unplug to see if the problem is behind or in front of it.
About a year ago I had FT do headlight and tail light mod.  I noticed on last trip rt back up light inop.  Today I noticed rt brake light dim, so I have swapped both bulbs problem remains on rt. Side.
Thanks in advance.  Trying to get ready for trip on Saturday

If not a bad breaker, most likely not, I would look for a loose wire on the circuit, posibly at the breaker, causing a higher amp draw, tripping the breaker.  I believe my breaker is in a drivers side mid bay behind a fiberglass cover, is that where yours is located?

Thanks Jack.  I am hoping someone can help me save some time locating the plug location closer to the rear so I can unplug it thus letting me know the problem is either in front or in back of that location.  No, my breaker is in the panel by the front door.

I don't think that there is a plug there to unplug. If the right side is dim that might be the place to start.

Jerry,

Take the trailer/toad wiring plug apart and see if some of the wires are frayed causing it to short out.  You also need to check the trailer  light converter magic box to see if it has gave up the ghost. Either one can cause some of your symptoms.

Mike,
I question the magic box.  I don't have a print but I cut the red wire hoping to remove power but it made no difference.  I will take the toad plug apart in the AM and look at that. 
Ron,  I agree on looking at the right side, was wondering is the wiring to rt. brake light ran from front or do they separate at the rear of coach.
I know the brake switches under the dash is not the problem.  I checked those.
Thanks again for all the help.
Also is that magic box something that is readily available?

Rt dim could be a bad ground.

Check the ground strap at the suspect light area.

Mike gets the prize!! I have a saying, Look at the last thing worked on!!  Wed. evening I replaced the trailer/toad plug HOUSING.  I had a problem with the lights not staying on and found that the housing had a small amount of wear - enough to allow for a bad connection.  I didn't have the center part so I changed only the housing.  Turns out they are not all exactly the same.  I pulled the center wiring part out of the housing and my problem was gone.
I want to thank everyone for their help.  Never seen a better forum period.  This is a good group always respectful and helpful.
