Electrical Problem - Share Info

Thanks to KStyer, Lumberjack, MKapp, Orangeman, and Owen, for the help on the electrical problem I have experienced. Lots of good advice. Now I am half way home. I posted a message that my interior lights were out, along with the headlamps and horn.
I was re-wiring the T-Top wiring with new units that go at the back post. I did not unhook the battery.
All lights went out inside, and the horn. I finally decided to check the fuses. 20 amp fuse out at the panel. Took care of all inside lights and horn.
Now all that is left, is to find where headlamps are not working at. Every light front, side, back, inside, etc., is working.
Thanks for help all, now back to it.

The easiest place to start is the dimmer switch. You can see if you have power to the dimmer from the headlight switch. There are a total of three wires to the dimmer. One from the headlight switch, one to the low beams, one to the high beams. From the dimmer you can go under the hood if it's okay there. If not it could be the switch. If there is no power there it is either the headlight switch or a power feed to the switch. The power to the headlight switch is not fused per say. It is from a fusable link off of the starter. The headlight switch also has a self resetting circuit breaker built in.
