Hey, Warren! I’ve had to replace a diode once so far, so of course I still have the rest of the pack of 20. I’d probably have just soldered into that wire a diode and called it good instead of spending the money on a replacement magneto. Did a replacement actually fix the issue? I’m guessing that part of the harness is not original and someone sourced the wrong one. Sorry, no idea whether the right magneto was actually defective and had a failed internal diode. I wonder how many years that machine was running on one cylinder!
The new coil isn’t here yet. The wire harness is original and hasn’t been tampered with. I never thought that the coils may have an internal diode. That’s something I need to look into. If it was my mower I would just install the diode and be done with it but on customer’s equipment I like to repair them so they are like they were originally.
@@wcjcnc Understood. I’m guessing about an internal, but given what you’ve just said I can’t think of any other possibility. I definitely would appreciate a followup video with whatever you figure out.
@@mattbaker6818 The part number was superseded but it should perform the same. Maybe they upgraded the newer one and that’s causing a problem with the old one? Maybe? Hell, I’m still waiting for the freaking coil. It’s on back order at partstree.com.
Swap coils from one side to the other. If problem swaps side, its the coil. If problem stays the same its in the wiring.
Maybe the rust on the coil has changed it. It now has more impedance.

Different part number coils are internally wired Different
@@mattbaker6818 I ordered the coil it supposed to have. You think a superseded part number could make a difference? I don’t know?
Both coils must be the same part number
