Alright custom #ebike dudes. I need help. I have no idea what's wrong, but my Ebike #battery will not turn on. As far as I can tell, it's fully charged, and I don't think any of the cells have failed.

My GUESS is maybe the #BMS has failed?

How do I go about testing and solving this. I have basic tech skills, as I'm a computer repair technician, but I don't normally do board repairs and diagnosis.

Symptoms:
Plug charger in, charger will charge for a few minutes, then change to green, as if the batter is fully charged.

Turning on the main switch under the battery does nothing. Not even the power level LED'S on the battery light up.

Not knowing what to test, I can get multiple -5v readings out of various locations. No idea why it's minus, as the neg probe is connected to the main neg output.

Out for another test ride on the electrified #cargobike. I reattached the brake cutoff sensors, did some cable cleanup, and added some rubber pieces to shore up the platform under the battery. Lovely but chilly day for a ride around #Provincetown. #BikeTooter #ebikeConversion

Finally got the battery for the #Tongsheng #ebike motor mounted where I want it. The cargo platform flexes a bit under the battery so I need to add some kind of additional support. Took the front box off for repainting. #CargoBike #ebikeConversion #BikeTooter

Nice read about turning a regular bike into an e-bike using the swytch.

Here's what the #Tongsheng #TSDZ2 install ends up looking like on my #Cetma #Margo #CargoBike. I haven't cleaned up the zip ties yet because the battery is only temporary (I'm going to get a smaller one that fits better).

Instead of the standard anchor bracket, I screwed a chain tensioner into that anchor bolt hole (https://cycles.eco/collections/tsdz2-accessories-parts/products/chain-guide-for-tsdz2?variant=) because eccentric bottom bracket + chainstay. There's some foam protecting the frame in case the motor moves.
