I am in need of some help on my 420. I recently received it from my father. When I brought it home it ran great, very strong. I parked it in the garage but when I went to move it to the barn for short term storage it would not start. I removed the starter and tested it on the bench with no luck. I had the starter rebuilt and tested it on the bench with it working properly. I replaced the starter. It still will not start. I took a jumper lead and jumped power to the starter relay and the starter turns over. Next, I unplugged the key switch and when I jump power to the red/green wire (two wires on the same connector) the started turns over. I have three 420’s so I took the key switch out of one that runs and tried that, still no luck. My key switch has six connectors. Four connectors are arranged in a square block formation with a fifth one centered above the block of four like a roof on a house. The sixth one is off by itself. The bottom two connections are empty (not used). The upper left has the red/green wire. The upper right has a purple/purple wire. The center top (roof) has a single purple wire. And the sixth connector off to the outside has a red/pink wire connected to it. Can anyone tell me what these different wires are for? What circuits are made in the switch when the key is on the off/run/start positions? Where can I purchase a new “PED14” terminal block for behind the key switch? Mine does not hold the wires very well after I removed some of them. I am guessing I may have a bad safety switch somewhere. I would really appreciate any assistance you can offer!
