I recently had the mower deck shut off while cutting. I reset the PTO switch and it came back on. But of course it wont work at all mow. I replaced the switch, no change. Traced back the schematic to the purple wire coming out of the ignition switch. I put a meter on it, and it's reading 2.1 volts. But on the hot side Im reading nearly 15 when running. Basic troubleshooting says bad ignition switch. Am I right? .
