no but did wires traced out, it will start with help of starting fluid if solenoid post are crossed with jumper wire. with the key it will engage starter but will not turn over engine, did voltage check and not getting any voltage on the starter post of solenoid when using key, so now need to find the bad safety switch, replaced seat switch and pto switch no change so will look at the other switches

Are you getting voltage to the small trigger wire when the key is turned to the crank position? If so, it is not it is not a safety switch issue, it is a solenoid problem.

Do you have a multi-meter or a single bulb 12V test light. Just randomly changing parts is not diagnostics, it's a lesson in futility.

Hello ACF,

StarTech sent you diagrams, apparently the second one is a match to your machine. Print off and study the diagram. Use it like a "road map" to steer you to where the problem is.

You also mentioned in an earlier reply that the key will engage the starter, but the starter does not turn the motor.

Has the battery been removed and tested by a parts store? Your meter can read 12 volts, but the battery can still be bad.

Voltage is only a potential to do work. It takes amperage to conduct the work. Your meter cannot test amperage that high.

used them to do trace the wires to check for any breaks in wiring, tested the battery with load tester comes up just in the good range. yes when the key is turned to start position the starter will engage fly wheel but not turn engine, but when i cross the two post on solenoid with jumper wire the engine turns over good.

Are you familiar with using a meter to do voltage drop testing?
