Electrical nightmare, 1968 cluster lights, parking lights, horn, etc.

I'm an idiot and thought the dimmer switch operated clockwise to brighten the dash lights, while it operates counter-clockwise to increase illumination :BangHead: Dash lights work and dim properly, horn works (pressing on right side of horn ring) with improved grounds & cleaned contacts.

Now my ammeter doesn't work at all. Maybe I overtightened a bolt for the large red/black wire, glad I have an extra gauge.


Also, the high beam indicator is very faint (almost no illumination) - I'll be checking the high-beam switch on the floor later today.
