Re: wiring in a circuit (piggyback)
When I originally read the lead post, I thought that he's wanted to hook up a charger or something that provided power to the bike. In that case a battery connection is the way to go. But I then realized that he wants to draw power from the bike. In that case there are considerations like how much. The O/G and O/W leads are fuse protected so there's minimal risk of melting wires. But the fuses might start blowing depending on how much additional load is being added and the OP was vague about just what he's up to. If necessary, you can increase the fuse size by 5 amps with minimal risk. But you need to be careful and it's best not to do so. Another consideration is that the charging system is sized for the bike as delivered with some, but not a lot of, additional capacity. Significant additional load can lead to stator and/or rectifier/regulator problems, which are well known here.
