Arcing - short question
I recently bought a used X-treme Baja 36 V bike. Spent the last week or so, cleaning, servicing the fork, general stuff. When I bought the bike, the PO turned it on, the motor spun, display worked.
This is a folding bike. When I went to reinstall the battery today, when the bike's terminals came into contact with the battery terminals the negative terminal arced. Do I suddenly have a short somewhere. Could the on/off switch
have broken when I worked on the bike and could it be broken in the on position? Could I have shorted the motor when I cleaned the gears? I have no idea how to even begin to look into where the fault might be.
Any suggestions welcome.
