Got a 2017 z125 KRT edition that someone had previously tried to punch the ignition with a screwdriver. Replaced ignition switch with one from eBay. The bike will crank but will not start. I can’t hear the fuel pump with key on. No spark when cranking. The oe ignition switch had a small gray wire that was connected to a resistor. I’m wondering if the aftermarket switch has the wrong resistor (or none at all). Do I need to buy an oe switch?
