Does anyone have any idea of what the A and Y terminals do inside the switch? I've used an ohm meter and it appears as if neither of them connect to any other terminal in any position. It's a Stens 430-674 aka AYP14031. 7 terminal 4 pos.

 I'm looking to rewire my Case 446 with a Kawasaki engine. The PO put in a switch with no M terminal and I'm replacing it. It currently has a relay off the light lead that grounds the magneto when the key is shut off.

 I'm hoping to avoid having to splice the regulator output, dashboard voltmeter and its light, headlights, and fuel solenoid all to the L terminal.

 Here's a schematic of one in use:
Notice they connect L and A externally? And it looks like there should be +12 placed on Y, I just can't figure out where it comes from.

Thanks, I used Visio and blanked out a lot of the original schematic, then added all my changes. The lights I'm adding to the rear aren't backup lights, but a wigwag setup for when I hit the street while snowblowing/plowing. I figure in bad weather I want to be sure they know I'm there. If I can find a cab I'll add a beacon to the top of that.
The 600 series has a FEL and optional backhoe, but they're pretty rare used. For a job that big I'd be tempted to bite the bullet and rent something larger and get it done fast. People have added FELs to 400's, and even 200's (the small wheel version), but the frame isn't made for that load. It's fine if you don't go overboard (snow or mulch not stones). Case beefed up the frame and created the 600 series just for that.
