Safety switch problem on Husqvarna Z248F zero-turn mower

[cliffeby]

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.

I posted this some time ago. You need to make sure that the seat and both arm switches are working and aligned. Easy to focus on the wrong part.

I have a Z254 and had a similar problem with the left arm. For over a year, it would cut the engine when it moved just slightly inward. Turned out that the right arm switch was loose. Check it and make sure it is staying closed when the arm is in park. Since I adjusted the right-arm switch, no stalls when unattended in park. I can't recall the cutout functionality, but both switched have to function. It's counterintuitive to have the left arm movement cause a cutout due to a right-arm switch misalignment.

First I am always Leary of any safety bypass. Hopefully you have a Fluke meter or equivalent that you can use to see where you may have an open condition on the safety loop. You may want to study the schematic some more because sometimes things begin to click after several attempts to read a tough schematic.

see if the "brake switch" is not stuck in the brake on position
