So I ordered up some 30" led light bars, (one front one rear, mounted on my roof rack in a protected position from tree branches and such) and I love them. I ran a power supply (block with 12 terminals and a 40A fuse) on the firewall, both with relays, and both have a 20A inline fuse as well. Went out about a month ago and had them both on, and the headlights, heater and stereo all running. After a few min I smelled something cooking (sadly, many of us know what cooking wire sheath smells like) and then the charge light came on and the batt gauge dropped. Luckily I was on my buddy's property and a couple minutes from his house. Popped the hood to find the fusible link smoked like a doobie at a dead show. Got a new link in there, and all is well. I know the old one was work pretty bad, and here's my question. I have the power supply hooked up after the fusible link where the bolt/nut connection is. With the fuses I'm running, it's ok (seems perfectly logical in my mind) to hook it up directly to the post terminal for the supply, as to not cook another one again, correct? I believe that's where the problem occurred, and that the F/L can't handle the added amperage if the light bars? Feel free to chime in, I know electrical about as much as a valve job on a Fiat.
