I've been having trouble keeping the battery up on my wife's Puma 150 and I wanted to try the 11 coil stator with the 7 pin rectifier. I got one from John who runs NYC Parts.
I'll post pix of the install later but here is the 12 coil that I am taking out of the PUMA. It's never really performed like I wanted:
You'll notice no magneto coil for an AC feed to the CDI, this system is pure DC in that the CDI gets it's juice from the battery via the black wire into the two port. Of course all stators are AC, it's the CDI that gets the system called AC or DC depending on how it's energized.
I wanted to do a little preinstall metering so I knew exactly what the system is like. I was planning by this VERY simple diagram of what I thought the system would be:
That will be the new system with John's stator and R/R. You'll notice a red/black hanging off of the stator unconnected. That's because this stator has a magneto coil which can supply AC to a CDI if you choose to use it. We will let it float and not put it to use. Instead we will use it as a DC system and let the three phase aspect of the stator power the battery which will energize the black wire with the key. The black will also be the voltage monitor and control the charging via the R/R. John, I know what you're going to say but I'm 90% certain this will work. But go ahead and comment if you want to.
But first I wanted to be sure the bike is wired like I think it is. So I was pretty certain the red wire is hot all of the time off of the battery. This is essentially like the Fashion's wiring so I'm very familiar with it. So, I should get 12v DC off of the red anywhere I test because it is hooked directly to the battery. Tadaaaa:
It wouldn't matter if the key is on or off, the red is simply an extension of the battery. Now I wanted to make sure the black was indeed enegized from the red with the key. If so, John's R/R should plug right into the system. So black with key off.
And with the key on:
So the pre-existing harness should work with the new R/R. Now while I'm thinking of it I wanted to show y'all something so you don't get fooled. A three phase has continuity between the three yellows because they are connected within the stator. But you should NOT have continuity from ground to any yellow. If you do you have a short and the stator is bad. So I test yellow to ground and OMG I have continuity!!
Unplug your auto-choke if it's energized by a yellow and all is right with the world:
The auto-choke needs a ground so the yellow will show a ground through the choke. So unplug the auto-choke to test continuity anywhere in the system, it will throw you a curve ball. I'm going to use the white auxillary power feed when I wire things back up so the yellow will no longer power the auto-choke.
Chapter two coming up!
