Hi all!

I converted my CGT-88 from analog to digital recently. I followed kvquattros instructions along with a lot of wiring diagram reading. It works perfect now but I have a problems with the light control of the display. It always goes on full light no mater how I have the rheostat and the surrounding light. It is something wrong with the electrical circuits. Is there anyone that have the diagram for the panel itself? It it anyone that have some ideas from where I can get it?

Here is a picture of the result:

I followed kvquattros lovely page and I have some corrections that I'll email to him later. I also have the digi dash service manual and it is really helpful. However what I'm looking for is a circuit diagram of the circuit board itself. I have a problem with the background light. It always lights on full effect. It don't follow the rheostat or the surrounding light so some circuit is damaged. I can't see witch of them it is without a real circuit diagram of the PCB. I checked all of the cables and connections but the problem isn't there to be found.

OK interesting, did you have the same problem?

Corrections? Go on then, what did I get wrong????
I've yet to see an internal circuit diagram for the dash, the only diagrams that I've seen are for the connections to the dash
