I just tried to power the scooter on and the power button led flashed white then red, went off and didn’t come back on since

 

There is a top bit that goes on top to cover this board which connects the battery to the board.

That might have been a little premature...

No I mean that’s what happened and why I’m trying to fault find I haven’t tried turning it on now.

 

Oh, sorry. Was it working OK previously?

It was working apart from a dead battery cell so I had a full battery rebuild and when I put the battery back on after it was rebuilt that’s what happened.

What is the part # on the dead D2?

What voltage is the battery pack?

Is there any way the battery could have been reversed?

 

It says “1631 UM” and the voltage is 40.2V fully charged also how would I check if it has been reversed. I did check the positive and negative wires in the battery pack and they both go to the correct sides for the positive and negative sides for this connector it sits in.
