I made a rookie mistake and blew zapped my BBSHD controller, what happened was I did the shunt mod and everything SEEMED fine. I made the mistake of testing the controller outside of the case just hooked to the bike, I only read .5Amp on my display but that could have been because there was no resistance. I decided to put the case over the controller to hook it up fully and try to see if it worked which was my second mistake. I should have pulled the controller off of the bike first but instead I tried to just put it on.
Here is where my question comes in, is there residual power on the controller in the form of a small battery or something like that? When I tried to put the case over the controller, I got a big zap from grounding onto the frame. BUT the battery was disconnected from the controller/motor, the motor was completely disconnected from the bike other than the controller being plugged into the motor. I have no idea other than some small power source on the motor/controller?
If there is a power source, how do I ensure that I kill all that power before I do this to another controller if I do ever decide to try again?
Also, does anyone know if the .5amp with no resistance is normal? I’m curious if my shunt mod actually worked or if I had screwed that up too?
I’m assuming that there is no chance of me figuring out what happened to the controller, but I did order a programming cable to plug in and see if I can do any troubleshooting, I didn’t see any obvious marking on the controller to see what could have blown.
Thanks!
