I have a Briggs 8hp I/C Model 196432 Type 917480 Code 062696 that I repowered my snowblower with. There is a white wire that comes from behind the flywheel cover. I tried hooking up a fog lamp from my car by hooking red fog lamp wire to white engine wire. When I touched the blower with the lamp to ground the engine wanted to quit. Is this an alternator wire or another cut-off switch wire? This motor has a switch for on/off which is also the low oil warning light.
