[hugger6933]

71 one ton been sitting since 15 and now wont crank. engine turns by hand all the way all the plugs were pulled to replace. Gas line is removed at the tank waiting on new sender. I replaced the tank so I thought while waiting on the sender it would be a good time to turn the engine over a couple of times to work out the wd40 I put in the cylinders. I put on the battery and no crank I thought my dad was the problem, and after I talked him into mashing the clutch[but he argued that he was in neutral] until I reminded him of an invention of a neutral safety switch he then pushed in the clutch. Still no crank The headlamps came on so the battery had contact the battery tester show over 12.5 volts in the battery. Guess I'll start by checking for power at the solenoid. Jim
