Hi, eveyone. i have a same problem as last time thread posted on 03/08/2010, but this time round it not a broken wire.

Here what happen;
As i put in the CD-card (Card Key) there's nothing, no light, no red and yellow LED light, nothing, like there no supply to the system.
I have the battery fully charge with a reading of 12.3 VDC.
All the fuse have check and it good.
I have a clear voltage reading at card in switch (R/B) same as the battery. When card is out, i believe i should have the same voltage reading at (R/blu) when the card is in, but it not. Believe something maybe wrong with the switch, how can i go about fixing it?

Thank you.
