Right Turn Signal does not work when lights are on?

[The Bandit]

New bulb, new fuse, right front turn signal works fine except it makes the radio/clock display blink along with the signal for some unknown reason.

When you turn the headlights/parking lights on, the right front turn signal ceases to work.

New bulb, fuse, and flasher. Same problem. I'm stumped.

Bandit, that sounds like a classic bad ground problem. When the ground for a certain light opens up, all sorts of crazy-looking things can happen as the current finds alternative paths to ground.
Trace where your common wire goes and make sure it gets to ground. You may have to remove bulbs to make sure you're not reading false paths. You should have zero ohms to the chassis from the common terminal.

HTH,

Steve

Thanks. I guess I'll start looking for the bad ground.

This is exactly what mine is doing only on the left side. I was wondering if you ever found what the problem was.

Thanks.
