    Guys,
    I can't tell you how excited I am right now. Last night I hooked-up the battery for the first time since completely re-wiring the entire jeep in order to run an electrical check. Everything works beautifully except one item...which is why I post "with an issue". My headlights do not illuminate...nothing, zilch. All other lights work except the headlights; high or low beam. When I press the switch between high & low beam, my "high beam" light in the guage cluster illuminates accordingly. So, what do you think? When I get home from work I'm going to disconnect the headlight bulbs and check for power at the connector. What else should be checked? Below I include some celebration shots of some of the lights:

    Make sure the grounds are good for the head lights. Bad grounds account for about 80% of electrical problems.

    With problems like this, you just have to divide and conquer. Start at the switch and see if you get power to the right wires with the switch on. Then trace the wire to the high/low beam switch, and see where the power goes from there. Keep tracing the wires until you get to the lights. If you get power to the bulbs, check the grounds, the sockets, the bulbs themselves, etc. Note that the bulbs have 3 connections: one ground that connects to both filaments, and one each to the high and low beam filaments.

    With the high beam indicator light working, that tells me you have power to the dimmer sw. Even if the dimmer switch is incorrectly wired, you should still have one part of the headlights working ( hi or low) so with neither head light beams working is a very good indicator that you have no ground (as stated above).

    Success!!! Thanks guys, it ended up being one lonely ground wire that just wasn't making a good enough ground. Lights work great. Thanks again for all the help.
