noticed under the seat a set of wires which have a plug on them. I think this is a location for a product called by many names, but its main purpose is to maintain the battery at a level that keeps the spyder ready to ride. If someone could suggest a quality and yet a affordable priced product I would be pleased. I have gone on line and the choice is huge, and so is the price, I thought about this site and all the good info from the bad, nothing like good experience to help out. I am now seeing that there is a great learning curve that a old two wheeler must go through before you can relax and enjoy this ride. Thanks I humble myself to the collective knowledge of this group.
