Hey Electrical gurus: Explain this to me. A year or
so ago, I charged the battery on my 20 year old
Snapper LT-11 Lawn Tractor, as I must do several times
a year. This time when I went to start it the starter
spun, but would not engage. I rebuilt it, and it did
the same thing. Tried Boosting, etc and no dice.
Finally realized the starter was turning backwards,
(polarity reversed). All I could figure was that I
charged the battery backwards????
New battery and everything worked fine. So, what I
just read cannot apply to my lawn tractor, can it?
