Hi guys...
After reading every post in this thread I think I have something interesting for you.
I have the bbs01 250w mid/crank drive installed on a performer trike.
My display will not power up, unless the battery is plugged into the charger.
Once plugged in everything works great.
The battery is charged, well so says the charger that came with.
(Side note here... Multimeter tests shows current leaving battery while unconnected to charger)
The provider has sent a replacement display thinking that might fix it, does same thing.
We are now waiting for a new motor and harness to arrive (was promised this would arrive 2 days ago and is not forthcoming with a tracking number, so I'm not holding my breath I guess...)
Anyway... You guys seem really good at fixing these things... Anyone got any thoughts as to WTF could be going on. This motor was supposed to make my dads new trike easy to ride... Instead he nearly has a heart attack every time he looks at it.
Thanks in advance for any suggestions
