Quick 214 Electric PTO Question

Not sure if this is where to post this or not. I have an RX95 rear engine rider. Engine runs fine but if I engage the deck it kills the engine. If I put in gear it kills the engine. I have a new seat switch. I can jump the tranny switch and it will go but if you engage the deck it kills the engine. Not sure if I am missing something simple or what. I have looked around for a wiring diagram with no luck. I have checked the switchs and all seem to work. There is some sort of little relay switch but its unclear to me what it is supposed to do so I realy don't know how to check it. Any help or advice will be appreciated
