Please be more exact in how you "jumped" the solenoid, charlie. Could be the solenoid, but let's eliminate things that can be fixed free first.

used screw driver on top of solenoid to touch prongs together and then it turns over

Sounds like you have a problem with the wiring or ignition switch. The Large terminal in back is connected to the battery, and you jumped it to the s terminal which is what the key would supply voltage to. You bypassed the key and not the solenoid. If you put a test light/voltmeter on the S terminal it shoild read 0V unless the key is turned to Start position, the S terminal should go to 12V

thanks wifisher, i just figured out my problem is in the control box.if i turn the key in neutral i got nothing,but if i move the gear shifter forward a little it starts to turn over.if not for this site i would of ran out and bought a new solenoid,thought for sure that was it thanks again,charlie1975

Probably need to adjust your shift cable a little. Put it in neutral and look at your shift linkage at the motor. Your neutral safety switch is probably not in the correct position.
