How do you bypass the safety switches on a murray riding mower 12.5 B&S engine. There are three of them?

Question

Are they grounds or are they just open.

Answer 1

These safety's are in place for good reasons, However if you are trying to see what is wrong;

1 safety is under the seat. When you sit down it  opens, it is 2 small aluminum pieces of 1/4 inch wide. Spread them to always  be open. 1 safety is contacted or pressed when the deck is in its highest position where the blades will be disengaged. A jumper can be placed in the wires to open that circuit. The 3rd is in the clutch/brake pedal, again it can be jumped or adjusted to be depressed when the brake pedal is depressed.

Hope this helps, if more is needed drop an email.

Answer 2

YOU DON"T. They are there for people like you who think they don't need safety switches.

Answer 3

I'm not going to tell you how to bypass a safety feature. But a switch either is normally open or normally closed until operated; at which time it changes state.Do you know what an ohm or multimeter is?
