Well decided to start my 1974 IH 574 gas this morning (been sitting idle for 2 months) and no dice. Battery is fully charged and the starter is fine ( jumped the starter and it fired right up). When I shut it off and then try to restart I get nothing. I am thinking either a bad ignition switch or bad clutch relay switch. Any other thoughts or suggestions? Also how could I test the ignition switch to determine if that's the culprit.
