Default Brake wiring on 85 FXWG

Hey guys, I'm finishing the wiring on the 85 FXWG rebuild and I have one question: When the breaks are applied, front and rear, the tail lamp goes out and the rear signal lamps light. Is this correct for this era bike? Thanks

Ride safe!

No. With the BRAKE applied, both the tail and brake light filaments should be illuminated and nothing at all should happen to the turn signal lights. One of them "boxes" is the best guess here.

When you guys say "boxes" or "magic box" what do you mean? Everything plugs into the terminal block.

Ride safe!

An aftermarket brake light/turn signal controller. Later models had one from the factory that goes out and is unobtainium. An earlier model such as your 85 would not have come with one.

Ok, thanks.

So I took one of the turn signal lamps and hooked it up as the tail lamp. Works like a tail lamp should so I'm going to take a look at the tail lamp itself, maybe a bad connection at the bulb or might buy a new unit altogether.

Ride safe!

Boy do I feel stupid and sorry for wasting everyone's time. I didn't have the tail lamp grounded and once I did everything worked like its supposed to work.

Thanks for the responses and pardon my rookie mistake. Gonna finish buttoning this all up and check again. I'm about finished with this restoration so look for my other thread once I get this baby started.

Ride safe!
