Hey guys, i just got a new board for my commando cab. Before I hooked it up, I doubled checked my voltage. At the PS I had 5.06V and the same at the harness. When I plugged in the board and powered up, I had gibberish on the screen. Powered down and back up again and it booted, but the coin mech would reboot the machine when a coin went through. I checked the voltage again with board still hooked up and there were still 5.06 at the power supply and only 4.65 at the harness. I powered down again, tweaked the voltage up a bit and everything worked great. Could the power supply be getting weak or is it normal for it to drop like that from the supply to harness when something is taking a draw from it?
