New seat kills motor.

[keithmadd]

I have a Cub CADET ULTIMA ZT1 42 inch. I got a new seat this morning. After putting the new seat on, then when I start the lawnmower it starts with no problem, but when I close the arm bars it shuts off. I put the original seat back on no issues. I put the new seat back on it shuts off again when I close the arm bars.

Seat safety switch?

Is this a new OEM Cub seat? Or Chinese replacement?

This is my favorite kind of problem: cut two wires, crimp.

OEM Cub seat

This is my favorite kind of problem: cut two wires, crimp.

There's one plug 4 wire into the one plug so which two to cut?

 

[Richard Milhous]

That's a lot of wires for a seat switch. Use a tester to figure out which need to be shorted. If it's not evident, you might want to consider reinstalling the original seat, or returning the new seat.

Can you use the seat safety switch from the original seat?

Another route beside the multitester route is googling the wiring diagram

Good luck finding a wiring diagram... what I don't get is why it starts at all, it's more forgiving than the Crapsman I just paid too much for. Anyway: just test the switch on the original seat to see what state the circuits should be in.
