I've been limping along my craftsman mower(model 917.272084) for quite some time and it finally gave up the ghost. When I got the mower several years ago, the 6 pin connector from the motor to the main harness was toast. it was a melted blob of plastic. FYI, this connector connects the ignition, fuel solenoid, and voltage regulator to the main harness. I cut the mess off and rewired but it would keep burning the connectors that traced back to the AC legs on the regulator. Long story short, the mower died a spectacular death last week by melting about 80% of the wiring harness in seconds. Its my fault since I hardwired past the fuse somewhere along the way, but looking back I think the regulator may have had something to do with it. I have replaced it anyway to make sure.
I purchased a new harness and still have to connect the motor electrical, but found something interesting along the way. The AC voltage at the regulator is also directed to the main harness and then to a relay. According to the manual schematic, the relay connects the two AC leads together, I think when the mower is running. However, the new harness, as well as the old, are not wired per the schematic. For example, the schematic says yellow wire to 87a and the other yellow wire to 30. The harnesses have the alternator connected to leg 87 and 87a. At no point in time will they ever be connected.
Does anyone even know why the alternator would be connected to itself through this relay? It makes no sense to me? Perhaps the harness is wrong and that's why it has been having issues all this time? I have been running it for a year without the AC wires connected to the relay. I found some other schematics for craftsman mowers that don't even have this set up. Any ideas?
