OK, dash lights and park lights appear to be working. I ordered a new turn signal switch and installed it. Also, I added the little light for the heater control. I hooked up the battery and once the ground cable hit the terminal: zzzz-pop....pop. OK, more fuses blown.
So now when hooking up the battery the HAZARD (15a) and the P WINDOWS (30a) fuse are blowing immediately. They are on the same circuit so it makes sense but what would cause these wires to draw too much current?
