I still havent returned with the mower to the lawn that needs cutting, the covids got in the way. Hopefully soon! Be Safe1

New blade on. Port installed. Just waiting on the discharge chute.

After some PB Blaster on the rust I was able to get the blade off the mower, and then the blade holder off the blade. New blades got delivered, was sharp but not sharp enough, and naturally I couldnt find my grind stone for the drill, so that'll get handled tomorrow. The old blade is imbalanced...

Laying on a cold garage floor trying to whack a 3/8" socket wrench with a small sledge gets old real fast!

Couldnt get the blade off (needed a breaker bar which I didnt have with me). Next step is replace the fuel filter (not sure where that is, it isnt listed in the shop manual at all) and mount the SAE charge/jump port. Possibly an oil change. EDIT: didnt replace the key switch since the old one...

It lives! Replaced the combo relay and the rectifier and she started right up.

Havent forgotten about ya'll, I just picked up the mower and brought it back to my garage to start repairs. I plan on: replacing the combo relay replacing the rectifier replacing the key switch replacing the fuel filter installing an SAE charge/jump port on the body, so I can leave the battery...

So the magneto spinning on the motor creates an ac current, which the rectifier converts back to dc to be used to run things like the buzzer and circuit continuity and charge the battery back in through the 5a fuse once the engine is running

This just hit me as I was walking back to my office, it provides limited 12v power for the buzzer and continuity circuits and to move the relays. I did not know about the return path thank you.

Ok I assume starting the motor takes more than 5 amps which would blow the fuse, but then why have a 5 amp fuse at all off the battery? What else is the battery doing besides starting the engine and there is a bypass around the fuse, so then why have a fuse..

Can you tell me what is Bl here? It looks like a wire that completely bypasses the fuse from the battery to the starter..

Agreed, I will test as many of the switches as I can. My Fluke has a tone for continuity thankfully

Thank you for the diagram, it is about the same quality as I have in the owners manual sooo I managed to find a higher quality one, and am attaching it here

I watched some videos on bypassing the combo relay using an external switch, but I know that also bypasses the safety features. The terrain is rocky and hilly and frankly falling out of the seat is an actual possibility, I would rather not be run over by my own mower. If replacing the combo...

The mower is in great shape as are the accessories (mulch kit, bagger). The only reason I am spending this much time on travel and diags is because the mower is a champ when it works. I wish I had pics of the mower to share, I have pics of every other damn thing lol. Regarding the cranking...
