I installed a Supernova The Plug II+ onto my bike tonight and I thought some others here may be helped by how to install it. The manual for it is really sparse and actually slightly wrong as the II+ is NOT the same as the II.
The II+ includes a cable that has a PAT module for power amplification which helps smartphones charge whereas the II has all the electronics in the cap.
1: On most bikes you'll need a new star nut to install the cables. The cables are routed down the tube and through the fork. I found that the size of the cable on The Plug was big enough that it would have been pinched once I had the new star nut installed so I filed it out a bit to give myself enough room to be able to move the cable when the star nut is installed.
Here's the star nut that nees to be removed:
2. Remove the star nut. I used pliers to remove the star nut. It's MUCH easier to drill it out; however if you drill it out you may lose the star nut in your tube and have to find a way to get it out:
3. Once you have the tabs on the top of the star nut pulled back you can use a bolt and a piece of wood to provide leverage for some pliers to pull out. When pulled out mine looked like this:
Here the star nut has been removed from the tube:
4: The cable on the II+ has a sealed cartridge with electronics in it that needs to go down your tube:
5: Here the cartridge is inserted into the tube. Make sure to insert it with the cable connector pointing up. This gives you the ability to vary the length of cable for the connector.:
6: Put the star nut back in with the cable going through it. If you don't have a specific tool to do it you can use a bolt through the star nut to tap with a hammer to insert it:
7: Get a wheel with a dynohub:
8: Connect the cable and install the Plug's cap. Make sure the loop for the USB cover is under the cap so you don't lose it. I have my The Plug pointing to the side so it doesn't interfere with my phone's mount:
9: Attach the cable to the dynohub. If you have lights do it IN PARALLEL. This means twisting both the wire for the light and the plug together. Do not use the connector on the light because that is normally wired in series which has too much of a voltage drop to start The Plug let alone charge a phone.
10: Spin the wheel and you should see The Plug's LED start:
Hope this helps someone...
