I'm guessing perhaps this is a 4-5 year old RZ-5424, model 965881301. New solenoid (3 pole), new ignition switch,(7 pole). I must point out that I had previously smoked a first solenoid as I was attaching the last battery terminal. Of course, I had to go buy a second one. was only a 1-2 second contact, yet a wire melted a little, so it was black taping
We have a single large red (only),from one solenoid pole to the starter. The other large red from the + battery side is accompanied by a much smaller red to the other solenoid pole, with a single, small yellow spade clip in the middle. Finally, a small black out of the harness to ground (to the Allen screw mount of the solenoid).
No headlights. The harness connect of the blade engage (safety) switch has 2 of it's 8 holes that are hollow, yet there are pins on the switch itself FOR those wire harness holes. ???. A 7 pin ignition switch is OK in that regard.
It has 1 or 2 of it's own idiosyncrasies. You have to pull the choke all the way up when the key is first turned. But then it's a feel thing to work the choke until it is running.
SO, as I turn the key to start it, it keeps popping the 20-amp fuse under the seat. NEVER the other 7.5 amp. The 20 EACH and EVERY time. That is my stopping point...over and over, without starting.
I've had virtually NO problems for the first 3-5 summers from this machine, but I'm at a loss here. I'm obviously no expert. Ideas?? It's grass cuttin' time y'all, and I SURE AS HECK can't afford any $50 an hour repairman.
