Upgraded it for better saftey after the short caused by two clips of the battery charger.
I spent nine minutes to install new switch, build a mounting plate. I’ll add a fuse on the circuit soon.
I had removed the front seat and put it back many times just to charge the battery without ever questining alternative way.
After the simple modification I don’t touch the front seat anymore. I open the rear seat, connect terminals of the 1A battery charger to each wire and turn on the swtich.
Positive wire, on/off switch, and battery postive terminal post.
Extra ground wire is connected to the metal piece.
