I think I am going to make and try out a solid state instrument voltage regulator. Mostly because I fried mine today and don't want to wait for a replacement to get here via UPS. I know after some reading the stock unit isn't a true 5v. It is a pulsed output that is supposed to average around 5v. I have run across lots of threads where people have made these with parts from radio shack that put out a nice constant 5v. I saw a couple of posts that at 5v the fuel gauge reads a little low because the gauges are actually designed to run at 6v. Does anyone know for sure whether it is 5v or 6v?
