Forgive my ignorance, but how do you actually connect the voltage regulator. I have a single-wire regulator, and see the wire I am supposed to connect it to, but how do I actually make the connection? Just make a cut in the wire, thread the end of the regulator through, then wrap it up? The one wire design is confusing me. If the end of the regulator is just inserted into a cut in the wire, wouldn't voltage just slip past it? I am sure this is a dumb question, but it haven't been able to find an exact explanation. Thanks everyone!

No such thing as a dumb question my friend. None of us knows everything and the worse thing you can do is not ask - Heaven knows, I've asked enough questions here! Mako has an expression for this, but I'm blowed if I can remember it!

Ideally you should get a supply of new male and female motorcycle bullet connectors, together with the clear protective covers that goes over each of them (long for female, short for male). DEET here on the forum supplies them, I believe, if you want to be sure of getting the correct items.

A wire stripper and crimper would be best for removing the necessary length of plastic cover off the wire that you are going to feed into and then connect the bullet connectors to. However, I have used scissors, a strong fingernail and pliers in the past!

In terms of practical demonstrations of how to attach the bullet connectors to the wire, demos on youtube are far better than anything that I can ramble on about here! Probably get yourself some old wire to practice on first if you can.

Finally, if you haven't seen it already, I am attaching Yamaha's own instructions on where to wire in the regulator.

Please note that you will need to find a location on your bike to attach the regulator to. I haven't done mine yet, but I shall make up a small bracket and put it under one of the bottom yoke (triple tree) clamp bolts. The nearer the headlight it is, the shorter the length of wire that you'll need.

Good luck, take your time and don't be worried about requesting any more help or info.

Ah, ok that makes sense. Thank you so much, this is exactly the explanation I was looking for! I'm nearly done with my wiring, and this was the last piece of the puzzle.

Voltage in wires is similar to pressure in pipes. So think of the one-wire voltage regulator as a "pressure relief valve" that bleeds off the excess pressure (voltage) in the pipes (wires) and brings the pressure (voltage) in the system down to a safe level.

(Note that the metal housing of the regulator needs to be grounded for it to work.)

Thanks, that's a helpful metaphor. The electrical component is slowly seeming less daunting.
