i started my s-10 and letting it warm-up when i was ready leave i hit the headlight switch and the truck stopped running immediately and will not start now but will turn over. i found that the headlight switch hot side was shorted as well as the hot side. i have traced short back where wiring harness goes thru firwall. with the connector disconnected i have 12.5v on engine side the pins that connect to the 12.5v pins at firewall are shorted to ground. where do i look now.
