Can anyone think of a way to test a complete dash panel/ cluster before installing it to make sure it is not shorted anywhere? I’m specifically talking about a 62-3 dash panel. I have built a new dash cluster for my 62 but every time I try to install it I get a short from something. I have tried replacing various gauges thinking they were faulty only to see a short once it’s all installed.. I currently have it ready to try again with a new amp gauge but I would prefer to find out if it is good before I go through the hassle of changing it out. Any way to pretest the panel?
