Re: turn signal problem 93 yj
Bill,
I'm not sure I follow. The rear turn signal never comes on. Nor do the
front two ever flash. What does the electrical circuit of the right turn
signals have to do with the circuit for the brake? Thanks.

Re: turn signal problem 93 yj
Hi Ben,
The brake and the turn signal use the filament, therefore the column
switch must able to turn off the power to the side it is signaling.

The power for the brake lights runs from the brake light switch to the
turn signal switch, where it is divided and goes to two wires, one of
which runs to each brake light. when you turn the right turn signal
on, the switch disables the brake light for the right side and powers
it through the flasher instead of the brake light switch.
I'd say that if you are getting power to the brake light switch, and
power through it up into the column, then the turn signal switch has
gone bad.

turn signal switch, where it is divided and goes to two wires, one of
which runs to each brake light. when you turn the right turn signal
on, the switch disables the brake light for the right side and powers
it through the flasher instead of the brake light switch.
I'd say that if you are getting power to the brake light switch, and
power through it up into the column, then the turn signal switch has
gone bad.

Re: turn signal problem 93 yj
Gotcha now....
The brake and signal light element uses the fixture for the ground
connection. The running lights use a wire in the harness that screws
into the body for a ground.
You very likely have dirty/rusty bolts holding that one light fixture in
place.
I test them with a long booster cable. I tag the battery negative and
the fixture or the outside case of the bulb if I can get the cable clamp
on it or just use it as the source for the ground when testing the
power.
Folks also lose a brake or signal sometimes when they put brush guards
on the tail lights. This moves the bolts out to rusty spots.
