Hello Herarld , I do not have the serial # at this time. It does have a lightning symbol,I have reversed the leads to the solenoid & it does reverse. With the park brake applied if the direction pedal is pushed ( either direction) the engine will rev slightly as I believe it should. Release the brake and as soon as you move the directional pedal to reverse the engine is shut down or if you release the brake & attempt to plug the wiring to the reverse solenoid it also shuts down the engine. I will get the serial #. Thanks for your time Ted.
