We have an L3130 that is having an issue with the seat safety switch. I have been desperately trying to locate a schematic that shows the wiring on this tractor. I have not been able to locate the relay (if there is one) that is tripped by the safety switch. Currently the tractor starts with no problem but even when someone is sitting in the seat it clicks and shuts off like the seat is not occupied. When you put the seat forward and push the lever down, it clicks and then it does a second click and all shuts off. I am wondering if it is a defective safety switch or what is clicking under the hood.
