Update 2: pulled connector off emergency flasher to get meter box probes in there. Had 10.6, 11.75 w/ eng idling, volts going to swapped in emergency flasher when turn signals engaged. Electrical systems are a weak area for me. I've the FSM and wiring diagrams. Where do I need to start? I'm thinking maybe the headlight switch is bad. Electrical problems frustrate the %$#@ out of me.
