Hello all, just finished a trip in my 99 F53 Motor Home. Had some trailer wiring to update (new plug) and in the process of testing the lights on the tow I discovered I have no brake lights. Turn signals and running lights are all fine. No 4 way flashers either.
The multi function seems to be working, when I try to engage the flashers it DOES override the turn signals as it is supposed to. My understanding is that the turn signals and the hazard signals use the same flasher relay, correct?
I believe my pedal mounted brake switch is working as it kicks the CC off with just a touch of my foot. I've read lots of posts but most deal with the loss of brake lights AND turn signals and is usually a multi function switch problem.
I read a post on another forum that someone had gotten info from Ford that there is a flasher relay as part of a fuse but I can't locate anything in my manual. DOes anyone know if there IS a separate flasher relay somewhere for the hazards only?
Thanks to all who can respond. Darwin
meporsche,
Well, I hate to say this but, I'm just a tad confused too but, on a different detail. Let me ask you, did all the brake lights, turn signals, and four way flashers work correctly prior to the trip? What was the need to change the plug? The only reason I ask these it because I'm trying to help lead up to what may be the cause of your issue.
If all was well before the trip or, at least before the plug change (even though you say the plug change is irrelevant) then don't you think that:
1. It's possible you did something wrong in the wiring of the plug?
2. In checking the functions of each pin on/in the plug, AFTER the plug change, did, at any time, the brake lights/turn signals/flashers work?
Now, on a second note, If I recall on most cars/trucks/motorhomes etc. there are TWO flashers. One for the turn signals and one for the four way flashers. At least, again if I recall, on our last coach, a '99 Fleetwood Bounder 34V with the F-53 and V-10, it had two flashers. Also, at least in our Bounder anyways, there are a group of fuses, just under the tilt-able dash. That is, you literally can lift up the half-moon dash and it has a prop that you put down, to hold it up, like the hoods on real old cars (for those of you that can remember waaaaaaaay back that far).
Then, down in that maze of looms and wiring, is a block of fuses. The ones for the turn signals and other lighting reside there.
So, at this point, I'm assuming you've hunted for and found, where your turn signal fuses are and, have checked them for operation.
One more thing. On many, if not all, Freightliner chassis coaches, there is a completely separate set of fuses, for the trailer plug that has nothing to do with the coach tail lights. Now, does your coach have a separate set of fuses for your trailer plug? Well, not a clue. I'm by far, no expert so I can't say if it does or not.
May I ask one more question. Maybe I'm clueless but, what is the "Multi-function" switch you're speaking of?
