Ignition switch

[Dholiday56]

Where can I find a ignition switch for a Sears Super 12 Tecumseh engine, I've read that if I use the wrong switch it can fry my coil, this one has the starter generator. I've checked everything and not getting fire.

If you post a picture of it along with a good picture of the back terminal's (there should be letters on the back) I'm sure someone here can help you out..

NAPA has a catalog of ignition switches. Just take yours in and have them match it.

Dose the switch that is installed run the starter current thru the switch if so you may have to installed a starter solenoid as those OEM switch's are very hard to find a new replacement that will work is a Stens 430-538 this switch is for magneto ignition and requires a starter solenoid, well I was wrong here's a new one

Do you know what terminals were being used ?
If I'm seeing it correctly.. Clockwise..
B
A
M
S
R
L ?

L is lights
B is Battery
M is magneto
S is Start
I think A is for Ammeter or the charging circuit.
R- I can't Remember (Race?)

The "R" looks to be ground as there is copper under the terminal that goes to the switch housing. I've never seen an R used for ground. Look The M goes to magneto to ground out ignition and kill it. If the switch still works some, you can test the R to be absolutely certain. Put volt meter on ohms and with key in off position there should be connection between them and when turning key to any other positions there should be an open line between R and M.

The terminal at 7 or 8 o'clock doesn't seem to have a corresponding letter? The ground is at 9 o'clock. You can see the copper going under it to the housing. Just be CERTAIN that any new switch is NOT sending any voltage to M, the magneto circuit as it will fry the coil for good!

Yes that's the switch I thought finding a new one will be a task they have not been used since the 60's early 70's it will be easier to go with the switch I posted and adding a starter solenoid good luck

Yep I'm pretty sure its a ground the later Suburbans had a fiberglass/plastic dash so it needed a ground wire from the tractor to the switch

Those switches are out there it’s just hard finding the right one. Stens use to have a good selection. Like mentioned Napa may be a good place to check out. The problem is finding another model that uses the same pattern.
