what” this part?

Hi all,

I’m new here, and a DIY kind of guy who has no training in mechanics,
but can do basic troubleshooting and repairs.

My (’95) Polaris Magnum 425 had no spark. After reading many post on here,
I unplugged the two black wires which I found in the wad of wire bundles in the left front area of the four wheeler.

One of these came from the kill switch, the other from a square black electronic module with four wires (the black, a red-on-blk, a white, and a red-on-yellow).

The 425 started fine with the kill switch black either connected or disconnected, but not with the black from the module connected.

What is the square black module that I apparently need to replace; the coil, maybe or pulser?

I’m trying to attach a pic

thanks

Thanks guys
