Interesting problem trying to extend ATX switch
Ive had a working setup for about a month now. The only catch is that I have to goto the trunk and touch the two wires connected to the mobo atx on pins (I actually just cut the connector itself from an old case I wasnt using, and just plugged it into the carputers mobo ATX on pins). The reason I have been doing this is because of a weird problem I encountered when I first installed the carputer. I used 24g speaker wire to extend the wires up to the front and connected them to a momentary pushbutton I bought from rshack. Here's the weird part. I could successfully turn on the computer if the ignition was set to ACC only, ie the engine wasnt on. Now if I turn the engine on, I cant turn on the computer with this extension. If I uncrimp the speaker wire from the two wires connected straight to the mobo (these wires are about 3 inches long, the speaker wire was about 10 ft long), it will turn regardless of whether or not the engine is on. I gave up on it for about a month, so Ive been popping the trunk to start the computer everytime I turn on the car, which is obviously annoying.
Today I decided to try this again. I figured this could be some type of interferance, and speaker wire isnt exactly shielded or anything. So I cut up about 10-12ft of some old CAT3 cable I had lying around. I followed the same procedure. Basically I crimped two of the CAT3 wires to the two wires coming out of the mobo. Touching the two wires successfully turns on the computer while the ignition is on ACC. As soon as I start the engine, same deal, it wont turn on the computer. I dont think this is interference of any kind because I had the CAT3 cable coming out of the trunk directly away from the car. I hadnt run it up to the front yet.
So anyone have any ideas? Popping the trunk everytime to start the computer is a pain in the rear!
