Need a Serial Number first in order to get the correct electrical schematic
20z03055
For some reason I'm not finding a schematic for the wiring on this machine. Looked on SIS in a few of the normal places and the only thing I can see is a list of symbols used in a diagram but no diagram itself. In the parts section there is a list of harnesses but not much to indicate what goes where.
Thats what I have been running into also
Ken, I think we've come across this before. If you look in the parts manual for the lowest possible S/N range of 20Z machine IIRC a wiring schematic is there. As regards the ignition switch wiring I would imagine that all 20Z machines are the same.
On older machines, wiring information is in Troubleshooting......... View attachment techdoc_print_page.pdf
It would appear that my infallible memory proved to be, well, fallible....... However in my defence I will point out that I was correct in saying that a kind of schematic existed somewhere.
I recall a few older machines that had the wiring schematic in the operation and maintenance manual. It took up all of 1 page.

Cmark, Thanks now if I can remember that for next time! I had actually taken a quick look at the "Troubleshooting" page but did not see anything that looked to be about the electrical system. Now I see there is a "Troubleshooting" link inside of the "Troubleshooting" main heading where the simplified schematics are located. I knew that some of the older machines had the schematics as a page in the back of a parts book or in the operation and maintenance manuals.
