When I connect my (once fully working) Asteroids PCB to an AR-II and power it up, the +5V LED only lights up very dimly on the PCB. The +5V is drawn down to only about 2,3 V and R5 on the AR-II starts to overheat very quickly (so I disconnect it quickly).
I have a feeling there is a short somewhere, but about each and every chip is connected to the +5V....where the heck so I start ??
This is a sense modded AR-II, yes I'm normally against it but this is my test-unit.
