Bafang BBSHD won't power on.
I have a BBSHD 1000 watt on a Specialized Fat Boy (4000 miles and no issues) and I have a light kit which I added last summer. The headlight stopped working so I purchased another kit to replace the headlight. Long story short the connector was different so I figured I would just cut the wires and splice in the new light. The problem is that the wires were not the same color so I had to guess. I tried a few different times and in the process I think I zapped something and now I can't turn on the display. I have 2 batteries so I tried the other one in case I blew the fuse in the battery. That didn't work. I then disconnected the light assembly completely to rule that out. Is there a fuse somewhere that could have blown in the controller? Should I try replacing the display? Replace the controller? I guess I will just keep trying things until I can get the bike to work again. I was hoping someone has experienced similar and may have an idea what happened. Thank you.

UPDATE: It's working again!!
I decided to take the controller apart again last night and check the connections. When I put it back together I heard the motor try to move but then gave an error on the display 08 H. I looked it up online and it said to check the white connector with 6 pins. I found one pin was bent so I carefully bent it back and then got the motor to work. However, it stopped working if I tightened the housing on the controller. I took it apart again and arranged the wires so they were not crowded together and causing plugs to disconnect. I was then able to tighten everything up and take it for a ride around the block.
Thanks for all your help and your videos were my inspiration for building this bike. I'm in the process of buying some things from your site now and will definitely look to you for any upgrades needed.
Thanks!
