Tow electrical connection not working, must burnt out fuses. Looking for the fuses box

[donritam]

I have a 2015 FR Legacy's RB 340 looking for the fuses boxes to check out fuses. If anyone have any idea. Thanks

On the Berkshires, there is a 4" x 6" black box in the rear cabinet that holds the fuses for the tow lights fuses and the Legacy might be the same. Skip

On my ‘14 Legacy they were in the front outside drivers side bay as formerFR states. There are three small fuse blocks there under plastic covers.

From the varied responses looks like you are in for a day of hunt and seek. good luck let the forum know where you find the fuses.

I checked all the fuse no luck yet, Driver side front all works. The inverter compartment no luck. Wondering if a relay, I have no way to check them out. Any idea...

[formerFR]

how about the fuse in the TOAD itself?

Which box, check fuses all good

Do not know that much about motor homes but pickups have separate fuses for the trailer plug .

Good Luck !!!

Toad is good, no problem

You may want to call Freightliner at
800-385-4357. They should be able to point you in the right direction since they built the chassis. Have your VIN handy when calling.

I don't know if this will help but I had a similar problem and after checking everything else I noticed some fraying on the umbilical connection from my TV and the TT. The vibration of travel had shorted out two of the internal wires in the umbilical. Once I had repaired the umbilical everything worked again. The flaw had no effect other than power to trailer was compromised until I fixed the problem.

You appear to be speaking in plural. Specifically, what is not working. If it is multiple; tail lights (running lights), brake lights, turn signals as a groups, you may well have a bad ground. It is unlikely all of the fuses went at the same time. If it has been sitting over the winter corrosion may have set in.

Try spraying WD-40 into the 7-pin connectors and at the wire terminals

I ground the live end to a ground by mistake. So where can I find the fuses.

Did you try owners manual? On my motorhome , 2017 FR3 there are two black fuse boxes behind the front grill and above the engine. I guess you would call it the firewall. Your owner's manual or fuse diagram on the box cover will tell you which fuse. Probably be a 30 or 40 amp. I did the same as you, accidentally shorted wire and blew fuse. Also had to search around but it will be about a 4x6 black box and likely there will be two, one for smaller fuses and one for larger fuses.
