'85 CJ7 Signal Problem

I just got an '85 Jeep CJ7 and the lights and brakes work fine but the turn signals won't work. When I bought it, they didn't work until the guy went to his truck and got a "signal relay" and plugged it in somewhere under the dash. Then they worked. When I picked the Jeep up the next day, they didn't work so I'm assuming maybe he took his part back. I never thought to ask him where/what he connected and he's out of town now ...maybe you guys can help me.

Also, the hazards sometimes work, sometimes don't. I'm not sure if this is related? Also, when I turn a signal on one way and press the brakes, the opposite brake light comes on but the one on the same side as the signal doesn't. I'm assuming this is normal for older vehicles but maybe not?

I tried replacing the little round 2-prong flasher lamp thing that goes into the fuse box and that didn't help.

Thanks for any help!

Hi Griffin, I there must be a short in the turn signal wiring and the seller removed the flasher to save you a dead battery, as you said you, replace the flasher, like there was only one, there are two, one for the hazards, and one for your directional as in schematic:

It may help you to find theshort put ohm meter on the red trace wire going to the turn signalswitch, then start up plugging wires coming out of that switch, untilthe short is removed. It is normal for the switch to disconnect the rear tail stop lightsto the side the flashers will be using.

Yup, that's exactly what the problem is. Thanks for the schematic too! However, I have a problem with your solution. The flasher part for the turn signals has no metal connector pins inside. I even jammed a connection tester rod in as far as I could and got no signal. Does this require a very special flasher unit or are there supposed to be pins (the hazard one has the two pins)? Is there an easy way to fix this without having to replace the whole fuse box? Any help is appreciated! Thanks!

You 'must' have the wires for the flasher under there because it was shown to work for the seller.

The normal problem with the lights is a broken bulb or a dead ground for the rear lights.

The brake and signal lights use the bolts on the light fixture as a ground. The running lights use a wire inside the harness for a ground.

When a brake or signal light fails (the glass comes loose from the brass base) or loses it's ground, it will steal a ground from the running lights. This makes it look like the other side is lighting up and all kind of strange things happen.

There are two flashers in the fuse panel by the by.

Heh! Success! There ended up being a wire that had a 90 degree connector on it and I plugged the flasher unit into that and badabing! She works! Thank you for all of your help and thanks alot for the wiring schematic! That will likely come in handy again. I appreciate your help immensely!

Mike Romain, nice to see you are still around. I haven't been here in about

3 years since I sold my '88 YJ but you helped me alot with that old beast back then and when I re-subscribed to this list I was hoping you'd still be kickin around on here!

Cheers guys! Now I'm off to buy some tops for this baby.

Yup. Even tho this thing has half the engine the YJ had and it's primary color is "rust red", it is a helluva lot funner Jeep already than the YJ. Way easier to fix, alot easier to modify, and it's not my daily driver so I don't have to baby it. Not to mention, it's almost all metal - no plastic dash crap, etc. Can't wait for some better tires and some accessories.

Yup, I am still kicking more or less. A little more than less anyway. I was a passenger in a passenger side T-bone hit in a car last year and recovery has been long, painful and slow.... :-(

The Haynes manual has a perfect wiring schematic for the 85 CJ and only costs twenty bucks or so. It also is accurate for anything mechanical I have tackled so far.

Wow, sorry to hear that Mike :( T-Bones are such terrible accidents. I'm glad your alive and I hope this won't impact your offroading fun too much. Thanks for the advice ...I'll go pick up a Haynes and tinker around with a few other things that I'm trying to fix.

Don't go anywhere tho! I'm sure I'll have lots more questions for ya :))
