After a long break from e-biking I recently got hold of a second hand Kalkhoff Pro-Connect with a 24v Panasonic drive. The bike has so far been working well and I've been making lots of modifications and repairs. I've taken off the motor/housing to reroute some of the brake/gear cables and also check the drive gears for grease and maybe add some more.
I've been following Flecc's excellent Panasonic info site http://www.flecc.co.uk/p/panindex.html and have taken off the motor from the drive. Unfortunately whilst it came off OK,I can't get it back on, or more specifically, on my drive the phase wires are too short to connect, or my fingers are too fat. So it looks like I'm going to have to fix the motor back on from this side and then try to connect the phase wires from the other side. Does anyone have any tips before I open up the six bolts and try to separate the housing into two halves?
I would also like to add a supplementary battery at some point, possibly to the frame bottle mounts ie the 'dolphin' style battery pack or maybe I'll just put something in the panniers. I'd like to wire the extra 24v battery into the main wiring loom under the existing battery and then switch it on when I need it rather than running in parallel. However I notice there's a sense wire in addition to the positive and negative. Does anyone know what this wire does? and will I be able to just wire an extra connection to the positive and negative terminals for the new battery or will the controller not like it?
Some pics of the bike are below, the guy I bought it off had himself got it second hand and didn't know much about it. Anyone know how old it is? It came with an e-bike vision battery which is not the original but works well, and and the Alfine 8 gear hub.
