This group has been a big help! Thank you in advance for helping with another question.
I’m working on a Craftsman riding mower (917255741). It had a 12HP engine but someone dropped a 15.5HP Briggs’s and stratton in it (28N707-0635-A1-9705132D). Electrically, it’s a mess. Said it wouldn’t charge. Honestly, I don’t think they even got it running.
I looked up a few models and landed on the Craftsman 15.5HP 917271554 as the example for the wiring. And this seems to be a pretty common schematic across a bunch of different models.
There are several differences between the old 12HP electrical system and the newer 15.5HP system including; two wires from the alternator, AC lights switched on at the ignition switch, fuel shutoff solenoid, 4 pole safety switches, etc. I’m planning strip out all the wiring that came with the 12HP engine and make up a new harness. All of that is pretty straightforward and shows up on the wiring diagram and the picture of the various parts of the harness.
The item that has me stumped is the Protection Wire Loop (Page 33, Key #52, part number 141940). It’s also indicated on page 32 in the drawing of the wiring harness. It shows it connecting to two wires.
However, it does not show up on the wiring diagram on page 31. The diagram shows all the other electrical components but there is no place in the diagram that shows this item, or where it’s connected.
What does this do?
Do I need it?
Where are the wires connected on the other end of that loop?
Thank you!
Dave
