I have installed the 5 inch touch screens into the monitor frames I got from Knight Rider World. I think because my 5 Inch screens were a little different than the ones that KRW uses I had to make a few modifications on how I attached all of the electronics to the back part of the frames. It took me the better part of this morning to figure out a good way to secure the boards to the back of the frames. I didn't have any circuit board spacers on hand so I used some plastic rigid tubing I had that I cut into short lengths and slipped over top of my long bolts that I used to secure the circuit boards to the back plate of the monitor frames. They seem to be pretty solid so unless they break I think they should be OK for now.
After I finished I soldered up the female end of the power connectors and then with fingers crossed I plugged them into my 12 Volt power supply pack. They started up OK so that is good, no shorts in the wiring. Hopefully I have enough separation between the circuit boards to allow for good air flow. I'm not sure how warm the boards will get if the monitors are on for any great deal of time, that is something to test out of the car for sure is a good endurance test of the monitor's electronics. I think they should be OK though. Next will be to test them out with the Knight O.S.
I have been thinking about the possibility of ever needing the dash to be powered without the car's Ignition switch turned on say in the event of a car show or something. My thought is that one of the Lower Console buttons could be rigged to supply power to the dash that would bypass the need for the Ignition to be turned on as that would be very impractical during a car show. So this is what I have come up with in the way of a wiring diagram to do that. Basically in my case the coloured lighted switches on my Lower Console use a Negative or Ground connection so the other side of the magnetic could of a SPST Relay would connect to 12V, this then would activate the Relay switch which would allow the connection to 12V to flow to the dash electronics effectively bypassing the Ignition Switch.
Well it was touch and go there for a while, I thought I was going to have to send my "Dummy" row board back to Knight Rider World for repairs or replacement. But with help from the fine folks over there at Knight Rider World we were able to figure out what was wrong with the board and even with my marginal electronics skills were able to fix the board and get it working. At first they thought it might have been a loose or broken solder joint on either one or a couple of the tiny components on the board. I did try re soldering them and then testing the board again only it still did not want to work in the middle display. So I pulled the board from my dash. Having it out of the dash I noticed that two of the pins on the chip were soldered together or "bridged", this it turns out sure enough was the culprit. Using some flux and a nice clean soldering iron tip I was able to remove the solder from between the two pins. I hooked the board up to my power supply and sure enough it worked like a dream. So thanks to the fine folks at Knight Rider World I was able to do the job myself with their guidance and save the hassle of having to ship the board back and wait for a replacement. Right on, I love when things like that get solved.
