I have had some stator problems in the past and going off of the good thread that DEcosse put out, not only did I need to put a new stator in, I needed to put a new regulator in. I went with the Compufire 55402 regulator. I figure I would pass on what I know and see about giving back to the community.
The first thing to know is as far as of this post (Sept, 5th, 2010). No one seemed to have the regulator so I needed to get it from the factory itself. I did ask the sales person why no one seemed to have it. He told me that it is going to eventually be available through all of the normal retail channels, it is just taking a while. The part itself is not new, it is just new having it as a separate component. In the past it was always available as part of a kit.
So bottom line, check Dennis Kirk, if it says available soon, just call the compufire factory and get it directly from them.
Here is a picture of the new regulator next to the original.
As you can see the Compufire is a little smaller than the original, it is a little higher but there is plenty of vertical room so that is not an issue. As luck would have it, the holes even matched up pretty close. I had enough slop in the mounting holes on the bike that no modification was necessary. Here is a picture of the new regulator on top of the old one. The pic isn't the best but the idea is conveyed.
The Compufire comes with weather pack connections for the stator and an empty female weather pack connection.
The nice part with this is you can go down to your local NAPA store and get the missing coponents. They should give you 3 male connectors. (Male metal pieces go in the female plastic part). They should give you something that looks like this.
The other nice thing is the power connection comes with a female spade, but also an inline fuse connection so the spade can plug into it and then the other end of the inline fuse has a connection to go on the bolt on the battery. It gives a little more flexibility that way. The 40 amp fuse is because the regulator is a 40 amp model.
I put the spade into the fuse and hooked it directly to the battery. The original regulator connection has 7 wires coming out of it and the Compufire has 5. 3 of the wires are for the stator and the other ones are ground and power. The original regulator has 2 power wires and 2 ground wires. If you trace the wires you will find they merge and are in the midway between the battery and the rest of the electronics.
What happens is if you don't use the 4 prong connector and just hook the power and ground to the battery is you have a 40 amp fuse from the regulator to the battery and from the battery to the other electronics you have a 30 amp fuse. (It's fuse 11 in the fuse box.) Leaving the 4 prong unconnected doesn't have any effect because there is still the normal wire that goes from the battery to the fuse box. I would have a pic but didn't want to get in trouble taking a pic of the service manual. The short version is think of a 3 way connection, one goes to the battery, one to the fuse box and one to the original regulator. Having the regulator not connected doesn't bother the battery and fuse box. If this isn't clear feel free to add a question to the post.
Have fun adding a Compufire 55402 series regulator to your machine.
