Well today I wanted to see if my computer would work with the opus 120. I have the VIA EPIA MII12000 Mini-ITX motherboard, 40gb hd and DVD rom. I wanted to see if everything was working before I perminitly put it in to my car so I went to the battery, connected the 2 black wires to the neg terminal and the 2 yellow to the pos terminal. The OPUS was flashing once which I know means that its being underpowered, I still put the ACC onto the pos terminal and the power light went on and the opus was now fashing 2 times. When the power light went on nothing happened nothing was moving. After this I put back the power for my house and everything is fine. Does anyone have any advice for me on this one?
