I would like to mount a shimano BT E6001 battery on a different ebike (giant) which has a different motor/controller. The battery holder (rack) has 4 wires coming out. Thick black and red are clearly for power and can connect them, but what about the 2 thin wires orange and blue? If I connect only the black and red the bike doesn’t work, instruments lite up for a sec, after that no voltage on battery. When the battery is in the holder, should the leds light up if I press the power button? They light up only when the battery is disconnected in my case.
