Re: Sixth terminal on key switch
How does that matter. I googled the above title and got some images, but no description of that terminal. Itís just a standard indak key for a magneto type B&S. Iíve got a dozen in my spares box, but none with sixth terminal. Alright, itís from a Walker T-something (only one with 26hp EFI engine). I looked at the parts and operator manual but neither show the wiring circuit, just wire harness connection. It appears to be a ground as itís daisy-chained to other devices (and itís not for illumination); which also means the key has two ground terminals. I know (at least on other magneto tractors) the ground is used for safety circuit. If safety goes to ground they wonít run. Most of my tractors are 30-40 years old and donít have too much safety stuff.
My local auto parts stores carry 2 mower ignition switches- a 5 term and a 6 term.
They are pretty common.
