Hey guys, since the 1960 deal fell through, i decided to go to a slightly more modern truck, and got myself into an '85 GMC sierra classic with a 350 and a 700R4 transmission. This was a great buy until it stopped starting, and im not totally sure why. I took my starter and alternator out and had them checked at advanced auto (both tested fine), and i got my battery tested as well, and it was fully charged and in good condition. Would this be an ignition switch? When i put everything back in, i heard the starter try, and it cut out immidiately, and i lost power to the cab. Any ideas?
