    Alright, I just tried to wire up some LEDs in my truck and I had disconnected the battery and hooked up ring terminals to the positive and ground in the engine bay. Also grounded the switch to a ground in the cab since it is lighted. After all this had been done and I had reconnected the positive terminal and hooked up an led and immediately the wires began to smoke and melt and got within a foot of the switch before it stopped melting (I had already turned the switch off). I used 16 gauge wire. Need some help badly. Nothing got hurt or anything except for my wires. Thanks guys

    Is there a fuse between the wires? Usually you want to run a fuse between the battery and lights to help fix that sort of problem but it sounds like you wired it incorrectly or maybe the manufacture did something wrong like a loop back.

    you probably got the wires wrong for the switch. Some how you connected the power wire coming off your battery to the wire your grounded to light up the switch. So you probably have the wires swapped on the switch....

    if its a lighted switch you hooked up the ground to the wrong terminal. 3 prongs... in out and ground. you were pretty much flipping the switch and making the positive lead connect to the negative lead.

    My switch had a +, a capital A, and a gold pin that had a ground looking symbol

    I wired the positive to the +, the negative to the A, and ground the switch from the gold pin with the ground symbol. I probably screwed this up

    What do you mean by negative to the A. You should not have 2 negatives. Your switch should have your power wire coming into it. Your output wire going to your lights and than the ground for the switch light.

    + goes to the battery. A(accessory)goes to the red wire to your led light. and the ground looking symbol goes to the ground(anything metal on your truck) the black wire on your led light also goes to ground.

    I wired the positive from the battery to the +. Then the negative from the battery to the A pin on the switch. Then I grounded the switch using the ground pin on the switch to a bolt that connected to the frame in the cab.


    What should I have done?

    Why nobody uses fuses for their wiring..what happens if the power wire rubs on a sharp edge and shorts out..or someother common thing like that ...your shit will catch fire, it happens. A simple fuse that costs just a few bucks will prevent all that. Relays are just as important as fuses!!!!!
