Update....with one exception, everything is back and we have life. When I connect the neg at the battery the passenger side turn signal flashes continually. Signal switch position makes no difference. Powered obviously but no changes to the signal switch or instrument panel wiring. Swapped out flasher unit, made no difference. Hazards work on all four corners, left is dead when switched on...followed the wires and did not find anything weird. There is a loose, inch long brass spring that was taken out from under the signal switch. Looks like out if a pen.... Signals did work before.
Appreciate everyone's tolerance for all this, Stovebolt mentors.
