Smoked wire, no more running lights?

I installed a nos kit, electric fuel pump, and accessories. all to my fuse block. I think I overloaded it. Anyways I had smoke come out of my dash, and know my night time running lights dont work(in the taillights). I have took the nos and stuff out, and now just want to fix it. Should I just take the dash out and find the wire that goes to the running lights, and go from there, or is there a popular place to start. thanks

Re: Smoked wire, no more running lights?

Fuses protect circuits from overload. I don't suppose your accessories were unfused were they? None of your fuses have been oversized have they?

Take a look at the back side of the fuse block. Disconnect the ground cable from the battery first. Go under the hood and loosen the bolt in the middle of the firewall bulkhead connector. I think it's 3/8" or 7?16". Under the dash remove the two screws in the corners of the fuse block. You can then pull the fuse block away from the firewall. There are either 2 or 4 plastic spring-tabs that will allow you to separate the fuse block from the dash side of the firewall bulkhead connector. Check there for burned wires.

Bad connections can cause wires to overheat - even at currents below the fuse rating. Bad connections have resistance and when currents flow through a resistance, heat is generated. Not only can the heat melt things, but it accellerates oxidation of the connection making more resistance and more heat.

Check your connectors for signs of overheating. Often times a single terminal in a plug will have melted the plastic around it.

Re: Smoked wire, no more running lights?

ok, I found a burnt wire at the headlight switch, tried to wire it back together and the wire started smoking again. I went ahead and ordered a new switch. I will go ahead and pull the fuse block and check back there to. No accessories were unfussed, or oversized. Im hoping its a short in my headlight switch. Also the plug that plugs the wires to the headlight switch is a little burnt, and I cant find just that connector without getting a new wiring harnes. Can I just wire the wires straight to the pronges on the headlight switch? thanks for the help

Re: Smoked wire, no more running lights?

I checked behind the fuse block and everything looks good as far as i can tell. I ran a jumper wire with a 5 amp fuse straight from the hot wire to the switch and it blew right of the bat. Could it be the switch or is there to much power coming from the hot wire?

Re: Smoked wire, no more running lights?

well, I got the new switch, and it was a little different from my other one. I got my running lights back, and everything else is fine except my dash lights dont work now. The ground is fine. Can I splice into my headlight wire and run it to my dash? This is starting to get on my nerves. thanks

Re: Smoked wire, no more running lights?

dash light wire needs to go thru a dimmer system thats built into the switch. Does the new switch have a wiring diagram and instructions that show which terminal is 'dimmer' ?

Re: Smoked wire, no more running lights?

no, no instructions. the switch has an exta wire, my other one didnt. Maybe i can run a test light to it and turn the dimmer knob intill i find it. Would this make my test light get dimmer just like the dash? thanks

The test light should work as described if thats the right connector.
