Re: Asteriods losing voltage

Dean, your edge connector on either the board, the card edge connector, or
BOTH is/are toasted. The Vcc or Vdd (common) contacts are burnt and not
passing enough current to bring the 5VDC on the MPU up to snuff. I suspect
the edge connector is getting hot to the touch....

What we used to do is to jumper the burnt out wires to the MPU directly
using a interconnect plug (like a car trailer plug set) so the board could
be removed for service. Purists add a very short extension card to the MPU
and replace the card edge connector.
