I have 2 separate dash clusters that I need to test the gauges on. One cluster has the actual gauges for temp, battery, oil and gas and the other has the fuel and idiot lights only. I have tried to find (via the web) if there is an easy way to test these off the vehicle w/o blowing them up. I realize that the oil gauge will have to have actual pressure on it, but will all the rest test with the same procedure...whatever that is? I hope I don't sound like an idiot myself here, but I am new to his "hobby". Thanks! Janine
