OK, no sweat. If it fails often enough, the best and quickest way to test it is to have someone try to crank it while you keep a test light on the crank wire (small wire) on the starter solenoid. If you have power there but no cranking, it's the starter or solenoid, usually I recommend just replacing the whole starter assm with solenoid. If there is no power there, then it's a switch or related wiring problem......Gilly
