This morning I replaced the starting battery in my generator as the old one wasn't holding a charge for very long.
I absent mindedly attached the positive cable to the negative battery node and the negative to the positive. I didn't have the generator switched on or try to use it, and immediately swapped them to the right way. But when I tried the generator - zippo, zilch, nada - no generator no happy.
Have I screwed up the electronics doing this? Does this do damage to the electrical system?
Perhaps pulled out a wire. (I wanted to try out the battery outside of the generator before having it bolted down inside and I pulled the cables gently outside the generator.)
