Another "no lights thread" 55 2nd 3100

[hb32]

I installed a new factory style harness from Classic in my 55 2nd with an alternator. I have no head lights, tail lights, park lights or brake lights. Suspected the switch so took it out and apart twice but appears good. Filed the breaker points and cleaned the internal contact points. Fuse is blown on the resistor for dash lights but should not effect the rest according to the schematic. Read somewhere that a bad dimmer would affect the head lights but does not explain the rest of the lights. signal lights work and all the bulbs appear serviceable. Horn is also not working but does work when connected directly to battery. No clicking noise at relay. Checked amp meter connections and swapped in a different one, still no joy. Have bat voltage on both terminals of amp meter. Truck will start. Trying to figure out what is common to all in circuit. is my second rewire on one of these trucks and no issues with the first. Any thoughts?
