Fix

According to the schematic (ACM4532-801-2P), the battery pack negative it’s connected to the power connector ground, which is then routed to the choke. So if the choke is broken the GBC won’t work. Anyway, try putting in batteries and shorting battery pack negative with board ground. The GBC should turn on.
