One Last Electrical Problem

You can always hook up a temporary ground during troubleshooting.

These are tough, but it's good to eliminate the easy stuff (like wiggling the bulb). Just work your way back to the switch.

Wish I could be there to help...It's always nice to have a helping hand.

 

It seems like nobody uses a test light. It's very easy to solve most issues like this with one. It's all I've ever used.

 

In this case you should have been able to remove the bulb and verify both contacts in the socket were working.

 

Yeah, but then sometimes that little light in the brain comes on and......well then we smack ourselves upside the head.

 

Awesome!

 

It's good that you enjoy working on your Jeep. I like figuring out problems like you mentioned, kinda fun and a learning experience too. If you have the time and patience making your own wiring harness would be easy enough. Not a lot to the wiring on our Jeeps.

 

Just makes it easy to see. I'm not sure why someone went to all the trouble to color it, but used different colors?

You might consider pulling the dash so you can lay everything out and secure the wires better.

As for the wire colors and connectors...Here's what my '71 has working from the passenger turn signal back to the terminal block (TB) next to the horn on the driver's side fender:

Passenger side turn signal light has one Blue wire and one Yellow wire (flashing circuit) running directly from a rubber boot out of the light's housing. From the rubber boot the wires are about 10" long and go into a black plug. There is also a short Blue wire going into the black plug for the side marker light. From the black plug there are 2 heavier gauged wires, one Black (flashing circuit) and one Blue (Running lights). These wires run up over the grill and towards the TB. The heavier Black wire goes to another black plug near the TB and converts to a smaller gauge Black wire. This is your flashing circuit for the passenger side indicator, it runs to the flasher and the turn signal switch. The heavy Blue wire screws to the TB post for running lights.

Driver side turn signal light is identical from the rubber boot, but the other end of the wires go into a black plug that connects to a brown plug. The brown plug has a Light Blue wire and a Yellow wire (see my pic). The Light Blue wire connects to the TB where the heavy Blue wire from the passenger side connects. It share the post with another Light Blue wire coming from the wire loom. This wire supplies power for the running lights. The Yellow wire runs directly into the wire loom. This is your flashing circuit for the driver side indicator, it runs to the flasher and the turn signal switch.

Here's a picture of my terminal block before my relay upgrade.


To convert the Jeep's wires to the V6 diagram:
- The Jeep's Light Blue wire is represented by the Orange color. This runs directly to the light switch.
- The Jeep's passenger side Black wire is represented by the Green color. This runs to the flasher and turn signal switch.
- The Jeep's driver side Yellow wire is represented by the Blue color. This also runs to the flasher and the turn signal switch.

I would put everything as I described and concentrate on the switch side of things. Also just to share how touchy these connections are. While I was tracing the wires out, my passenger side indicator stopped flashing. I had to wiggle the wire loom until it started again. I have clean wires and a great ground, but it looks like I have a mini problem to solve.
