Bought my JK, used a couple of months ago. Hella 500 comets were already installed and have worked fine until last week. I tried to replace 25amp fuse but they keep blowing as their being installed. I traced the wiring which appears to be a clean professional install. All connections are good, no exposed wires as their all routed using plastic flexible conduit. Wth?!? Any ideas would be greatly appreciated! Thank you.
