Brake and turn signal on toad fail

[Robfike]

Diesel pusher Land Yacht 1999.
My brake and turn signals work on the RV. Center brake light on RV does not work, and hasn’t since we’ve owned it.
My toad lights worked great when we left on our winter trip.
Now I have no brake and turn signals on the toad. Running lights work fine on the toad.
I think there’s a problem in the left rear corner of the RV where everything is wired. I get no voltage at my trailer plug for brake and turn signals.
Anyone else experienced this problem?
Thanks

It sounds like a blown fuse.

Finally figured it out.
Of course no complete wiring diagram to go by.
Power wire from engine batteries to Brake/Turn signal relays dead.
Fuse at batteries good, but crappy connection on fuse spades. So everything worked except toad brake and turn signals.
Cleaned fuse connections and now everything works.
Center brake light on RV is a separate problem it would appear.
