Cristiano,
I have a question concerning powering the PROGAUGE. I currently have a revburner and while awaiting the new product to arrive I tried wiring up the additional gauges so as to have it ready for the new circuit card. I plan to run a tach plus five additional gauges with lighting. I currently have a 1 amp power adapter and ran in to some problems power problems when I hooked up all the gauges and associated lighting (with the exception of the gauge signals as I dont have the new progauge yet). That many components seemed to put to much of a strain on the input power causing the tach to not function correctly. With a couple lights hooked up it worked fine but as I added more I believe the load became too much. As a work around I have ordered the following power supply which I think should be able to drive all gauges / lights. Did you run in to any power problems during testing? And do you see any problems with the power supply I intend to use? Provided of course I hook it up properly in regards to polarity. I have attached a picture of the 12vdc power supply and my initial schematic draft of the wiring.
