I didn't see any markings on the module itself.
I disconnected the neutral safety switch wires (2 that you can see in the picture) and made sure they were clean connections. I also left them off while trying to start the tractor. I was trying to isolate the issue. With the clip wire still hooked to the grounding stud on the engine block, spark still flew and tractor died. As soon as I pulled wire connector off, it was fine. So it is either the module gone bad or there is another short somewhere else in the wiring. Seems odd that it would suddenly do this so suddenly. Starter switch/key starts motor fine without wire hooked. If the key/switch was the cause, would it still start the motor with wire disconnected? I had Charlie (my neighbor) try to run the tractor with safety wire off. He said it ran fine, shifted and drove fine. He said he engaged blade once and it ran fine. Then shut off blade and back on and then the deck would not engage. Now I don't know if the safety came back to bite on the deck working too or did he just throw the belt? I'm going over this week to check it out. Ultimately I'd prefer to completely fix the safety issue as I'd prefer not to let him run this without safety mechanisms in tact.
