e-bike: re-wiring part 1

Feeling that it's time to get back to work on my e-bike project, I've started work on rebuilding the electrics.  This will involve two sub-projects; re-building the battery pack and stripping and re-building the wiring harness.

I've disassembled the battery and will be ordering a few bits and pieces to put it all back together again as sort of a cylinder. I'm considering putting in a fan to help with cooling and maybe a heating element for when it's cold. Like today was.. nearly froze my fingers off riding home on my motorcycle. >.<

I've stripped the wiring harness back to just the wiring necessary to make the motor work. Here's what it's trimmed back to:



[Edit:  Oops.. made a mistake on that diagram.  I'll upload a fixed version shortly.]



(The light grey parts are what I've chopped out.)

I've a bit of soldering to do and then I'll hook everything back up to test if it still works.  It'll be very stripped back functionality wise; just a twist throttle and that's about it.  Once the battery is connected it's ready to go, no key, no safety switches that detect if the brakes a pressed, no brake lights, no turn signals, no horn, no anti-theft system.  Phew.

Once I'm sure I've not killed it, I'll start building my own on/off, lighting, control panel, etc. systems based on 5 volts.

I'm also planning to rebuild the motor wheel, replace the front one and do some hack and slash on the frame.  This project is going to keep me busy for a while. ^_^
