Also you don't need power to test hub motors, you just short any 2 of the leads together and spin the wheel, if it hard to turn, thats good. Do the same with either one of the leads you already did and the one you didn't, again, it should be hard to spin.
It has a cheap controller on it already with a single 7-pin plug. The only external function on the harness is an on-off button on a strap of Velcro.
The new brushless controller from Amazon (stock pic below) was $10.69 (it fluctuates between that and $25.64 depending on who's selling it), so I'm not particularly upset at the cost
. I just hope it works with the Bafang/8FUN hub.
I hope it'll run with just the
hall assist sensor and brake lever cutouts hooked up - which reminds me, it looks as if the brake levers are going to get swapped out on this bike...again.
I'll remember that trick for the hub, but it really wasn't difficult to take a G-scale model railroad controller, set the polarity right, and run 24V directly to the motor controller. That way, I know the original stock system is working as well.
I'm crossing my fingers there's enough wire in the stock harness that I can just re-use it for through-the-frame cable routing. Have yet to find a source for 3-conductor wire that seems to be correct. Not to mention that I'd like to find a better plug to solder into the hub and wiring harness - this one is huge and has no obvious weather seal.
