......seems easy enought to test nuetral safety switch...find where the nuetral safety switch plug is by the steering column where it comes up from shift lever on the tranny. Start the truck and then unplug the switch and see if it does it......sounds like it is shorting the hot side of the coil, which I could see might happen if it was '75 or earlier with points, '77 should be electronic, right?
