Here is what I have. My build (
https://67-72chevytrucks.com/vboard/...d.php?t=798538 ) I am building a 63 C10 and have run into an issue. When I put my gauges fuse in it takes a couple seconds after I turn the key to the on position (engine is off) and then the fuse pops. I have a new wiring harness (22 circuit universal Speedway Motors) that I have put in the truck. I pulled the gauge cluster out of the dash and pulled the gauges that require power (gas, temperature and battery gauge) then put the fuse in and then one by one plugged the gauges in. When I plugged the battery gauge in the fuse popped. I checked the resistance between the two wire connectors on the back of the back of the battery gauge and I had 0 resistance where I had resistance on the fuel and temp. So I figured I had a bad gauge. So I ordered a new gauge went out plugged it in, put a fuse in and then turned the key on. Smoke immediately poured out of my 100$ gauge I just ordered then the fuse popped. The engine is not running so I am confused at how that much power is going to the gauge to do this. The only thing I can possibly think is if the wire size is different and allowing too much to flow or if the old fuse panel some how had some form of resistor in it. Everything worked fine before the new wiring harness.
