I have a 74 with a stock 350. It hasn't left the garage for many years. I tried to start it with no luck. The starter bench tested fine. I have 12 volts to the starter and if I short the posative lead on the solenoid to the small lead on the right side(drivers side), it will turn. It would start last year and now not even a click. It seems the neutral safty switch works O.K. It must be an ignition wire but I have no clue how to check. Any suggestions would be appreciated.
