I have been working on this tractor I purchased at auction last spring, it has had issues, miss in engine, leaking radiator, and other items, I finally replace all 4 injectors, tractor sat about a month, went to start, just get a click when pressing button, finally used a screwdriver to short out large upper terminal to small terminal, spins over and starts, figured must need a new solenoid, I installed one today, from reputable auto parts store, no change, still just clicks when pressing starter button, use screwdriver to "weld", spins over and starts, perhaps I do not have wires connected properly?, I hooked them up as they were with old solenoid... looking for suggestions..
