Hi all,
Yesterday I bought a broken Denver SEL 80130 second hand, with the seller claiming it only had a loose wire.
Checked it out: no loose wires, but also no moving scooter.
When I turn on the display, an empty battery indicator flashes. Headlight works fine though.
Any ideas on where to start looking?
Checked: battery voltage is 41 volts. Voltage is properly supplied from the motor controller to the display, also measured at 41 volts.
This scooter has a closed blue block as a battery, with the BMS inside, so I can hardly check it. However, the charger stops properly when the battery is full, resulting in a green light.
What could cause the display (or BMS) to still think the battery is empty?
Edit: I also connected a different new 24 volt battery to see what happens: exactly the same.
I actually bought this scooter to repair my other scooter, that display (same display) doesn't do anything at all, despite receiving 24 volts (it's a 24 volt battery/motor system).
Thanks for any tips in advance!
