85er CJ-7 small electric Problem

Hello people,
have a small electrical problem with my '85 CJ-7 I have completely restored it and've found now that if I had not turned on the ignition, you can turn on the light. Only the low beam, not the high beam. Also go all the instrument lights. Does anyone have an idea what I could have clamped wrong? Have the harness actually mounted so again as I have removed it.
Thanks for any tip


Greetings from Germany

The lights (headlights low and high beam, tail lights, instrument panel lights and side marker lights) are not from the ignition switch. You can turn them on at any time.

I attach a diagram of the ignition switch and fuse box which shows the panel lamps being fed from the light switch. Missing from the diagram is the headlight feed that comes from the same switch.

The high beam and low beam are fed from the same supply, it is switched between hi and low by the floor switch (not shown on diagram). You may have a problem with the switch itself, the connections to the switch etc. Can you turn on the high beam with the ignition on??

Power steering takes Dexron ATF.

You only need limited slip stuff if you have one. To check, jack up both rear wheels and turn one by hand. If the wheel on the other side turns the same way, you have a traction device, if the tire turns the opposite way, you have an open diff or worn out traction device.

I have found that the addition of an oil additive for the limited slip would restore that function if the oil had no additive.

I have one rear axle that I though was an open diff until I pulled the cover off and found the limited slip. I added the friction modifier to the oil and it started to work great until I spun the hubs....

So if in doubt, add the stuff I guess eh. It won't hurt anything except your pocketbook.

ok I check tomorrow once the tip with the wheels, because on the case I can not see any more code.
The Dexron ATF is purchased.
is now just the final phase to the CJ to finish, and much is new for me because everything has made my dad before he died is up.
there are now all just have to do little things, but staying ....
I just have problems to adjust the doors .... still has the msd ignition modules install and wire, the axle oil change, transmission oil change, put fuel lines for electric gas pump and the pump (Carter)
then I have to turn the distributor slightly because the vacuum outlet is too close to the V-belt from the power steering pump

thanks for your help !!!

regards miami-boy
