Turn signals, won't work Options

[arkitect]

I'm just about an idiot when it comes to electrical. Is there a simple cure for my lack of turn signals on my 73? And before you say look at the electrical diagram....forget it. Too small for my old eyes to read much less figure out.


They use to work, but over time don't anymore. Is there a ground up front for them, relay went bad, fuse. What is a common thing that I might be able to fix?

Any help would be welcome.

The 3 wires are the ones to the headlight motor. Don't know if suppose to have constant power without the headlight switch on but the green and red wires do, both sides. Normal?

Also, the master cylinder only has one connection for a ground not two like the old one. One is just loose, do both need to be grounded?

Did get partial signals to come on, driver side is brighter while the passenger side is very dim. Any suggested solutions?

Normal. When the headlight switch is off, it sends power to the "put the light down" circuit. There may be power to another circuit as well when the light is actually in the down position; that acts as a "brake" to stop the light in the right position.

Also, the master cylinder only has one connection for a ground not two like the old one. One is just loose, do both need to be grounded?

If it only has one connection, the brown/white wire goes on there. That goes to the "YOUR BRAKES HAVE FAILED" blinking light in the combo gauge. The single-pole sender is grounded through its threads, while the two-pole sender takes a brown ground wire on the other pole.

Tie the plain brown wire up out of the way, in case you ever wind up with a two-pole sender in the car again.

Check the ground path for both lights. Sometimes a bad ground will force one light to ground through the other, making one bright and one dim. I had that problem with my headlights once.
