I have a problem with a Husqvarna Z248F zero-turn mower. It's a 2015 model. When I move the steering levers inward with the seat occupied, the motor stops. It seems logical that the problem is probably with the safety switch under the seat. I've removed the seat switch and by using a c-clamp, I am able to depress the switch to close the electric circuit and keep it closed while I move the steering levers inward. The motor still stops after doing that with the seat sensor circuit closed. Can someone suggest where I should look next to fix this problem? BTW, I put a piece of PVC pipe between the steering levers so I can start the motor and keep it running while the seat is not occupied. I have the electric wiring schematic for this mower but it is the worst schematic I have ever seen and of little help. May I hear your suggestions and comments, please. Thank you.
