Hello,
I have used and wired SP dynamo hubs with twin wires before but I am having trouble wiring my SON SL hub using coaxial for the reason highlighted below.
For those not aware SON do a hub that does not require plugs and makes contact with an insert embedded in the fork strut. This system is called the SON self connecting systems or SL for short. One end of the hub is live and the other end is the earth. So there is actually only one connector on the fork, not the hub on the live side.
I have the following:
- Tout Terrain Silk Road with SL fork
- SON SL front hub
- SON front light
- SON rear light
- All cable is coaxial.
My question is this. What do I do with the earth part of the coaxial cable that comes down from the front light as this is surplus to requirements (I think)? Do I just protect it by heat shrinking it up and ignore it? I did get it working temporally by connecting the earth part of the coaxial cable to the mudguard strut but this seems fiddly and in contrast to what the system is about (simplicity). And it would not work if I decided to run without mudguards, if I decided to put bigger tyres on etc. Plus it has stopped working altogether now, but I know that is probably down to loose connections.
I have tried and tried to find documentation on the SON site or Youtube videos which are normally very useful, but with this being a very rare set up I cant find s single thing on the subject. Peter White cycles touch on it, but not in as much detail as to the wiring.
Your help will be very much appreciated.
