I cut the ends off the cables and wired the 8 small wires together using a small terminal block, a temporary measure to see if it would get things working again. It was all a bit small and tricky, but after all 8 wires re-linked, the lcd lit up and a quick test holding the wheel showed it working.
The bike is now all back together as an e-bike, I have kept the temporary connections for a while, wrapped in plastic bag and insulation tape. I don’t intend on keeping it like this for long, and I won’t take out in the rain, but hopefully it will keep together for the 20 miles a day.
A 10 mile test ride showed it working all apart from the speedo and power on the lcd. I didn’t think it would be too bad until I discovered that because the lcd thinks the bike is not moving it then switches off after 5 minutes – which it did a number of times (well, every 5 minutes!). Investigating this online I found that I am not the only one to have a pin corrode on this particular kit although I could not see what people had done to sort it. I did find out however, the Das-Kit lcd takes 8 wires in, other lcds take 5 and this is because the Oxydrive kit takes wires from the brakes into the lcd and not straight into the controller. It keeps things tidy.
The plan, next weekend maybe, is to determine the 5 wires that are needed:
- Red (VCC) – power +
- Blue (K) – switch
- Black (GND) – ground
- Green (RX) – receive
- Yellow (TX) – transmit
This leaves 3 wires extra, the two brakes and ??? My hope is one of the 5 is not quite making a connection and so unable to show the speed and power load. I would think it could be the green wire. If I have no luck, then maybe look for a new/different lcd (5 wire). I assume/hope colours are universal in the world of ebikes…
