I wouldn't be surprised if you could buy them on Amazon.
And speaking of surprised. Today I took another stab at figuring out why the Winter SEE hasn't started for well over a year...as in won't even make a click when hitting the starter button.
Had already verified that it most likely was an issue with positive, not ground. Had a varying voltage of around 12-14 when checking the starter switch lead and at the solenoid. Looked in the trouble shooting section yesterday evening, made some notes, and decided that since I checked the fuse last year, lets start from the back of the many pages.
Put a basic rocker switch on the starter button wires (had used those as a measuring point), pushed in the clutch as I put the test light on the starter connection to get a reading from the last point in the long chain - and it fired right up.
Put the connectors back on the original starter switch, anticipating having to change it out, and it started again. And again. This was so encouraging that I decided to check other stuff.
Found that the right rear blinker/brake light doesn't work. Doesn't matter to me. But the front LED work lights didn't, and that is not good. That the rear LED work light also doesn't work is okay, but now I'm enthused enough to spend a bit of time to make it all function. Just because.
