This one is a little bigger than a Razor.
Mice had been nibbling on some of the wire insulation. I only saw one wire eaten straight through. I just stripped the two ends of that and twisted them together.
The scooter uses 2 x 12V / 12AH sealed lead-acid batteries. I pulled both out and tested them. Do you think 0.58V qualifies as dead on a 12V battery?
Even hooking them up in parallel to a Yellow Top, I was only able to get them as high as 7 volts.
