That would make sense, because the symptoms are all pointing to a fuse type situation - especially because everything started at the same time. The 30 amp fuse blew and when I went to activate the PTO for first time - it initially, very briefly, engaged the clutch  and then died. After that no power.  The diode was definitely fried - when I pulled back the shrink wrap - it disintegrated into powder.



I have my manual and a copy of the schematic.  I see the diode on there, just not sure if it's required or not.  I don't understand how I am able to just provide 12v direct to the clutch and it works, but not through the hot lead that contained the diode.

Eric, the  model number is 917.276022 on this unit. Not sure best way to reply to your questions since there is no reply button.



I also read someplace it could be the clutch itself which may be blowing the diode?  Don't really use the mower that much (1x/week) on 1 acre.  I also did confirm that when I installed another pto switch - it did indeed kill the pto switch which engages the blade (2 down now).  Not going to proceed until I have clearer direction :-)

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
