John Deere 520 Starting Issue

[markerc2015]

Help!! I have a John Deere 520 with a starting issue. I had so recent work done to it. Had the starter rebuild with starter switch. Regulator & generator gone through also. Started right up 3 times over a week period. Now this weekend it just rolls over & fires but quits firing after taking your foot off the starter button. I've replaced the resistor still doesn't run. I've checked all the wiring out, nothing is broke or coroadded. Everything tests out good on a voltage meter. I'm just not sure what to do. Any replies would be appreciated. Thanks!

Somewhere a wire is wrong. Maybe the ignition switch - a short length of wire with 'alligator' clips may be your friend. HTH

The switch is shot

You need a new starting switch that sets on the starter. Its wired so that when you step on starter, 2 poles touch and runs current to the coil so it has 12 volts to start. if switch goes bad it will start,but shut off as soon as you let up on pedal
