I have a 05 yfz 450 that I tore down running to paint the frame. Put it back together and it's not getting any spark. I started going through it with a multimeter and found diode #1 was reading 1 on the meter both directions. The start switch wiring runs to this diode. Is this the reason behind my no spark issue? I'm going to replace regardless but just don't want to get my hopes up and it not be the problem.
