This wire gets pretty hot while driving, not hot to the point that its smoking or anything but just hot enough that its unconfortable to touch.

its only getting hot on the side that connects to the ignition switch, and ive never had a fuse blow.

This wire has been hacked into by a previous owner along with a couple others from the ignition switch (im assuming turbo timer or alarm) The reason i found this wire was because where it had been hacked it seperated and caused my car not to start.

 

The fuse wouldn't blow if the patch is before it. The wir is getting too hot because too much current is being pulled through it. You are running the risk of possible electrical fire.

 

^Agreed. You have an exposed wire partially grounding out/misdirected somewhere along that portion of the line. You need to repair it before it tries to weld your ignition switch or starts an electrical fire.

 

Hey XSTransam...I just PM'd you about a different matter.

 

if a wire isnt large enough gauge for what's being drawn through it......it can get hot.

 

You said "its only getting hot on the side that connects to the ignition switch". If you mean it only gets hot at the end that connects to the ignition switch, then it might be a problem with the ignition switch itself. Wires are uniform in resistance (except at a poorly made joint) so a wire that is carrying too much current will be uniformly hot along its length.

That wire carries current to a lot more places than shown in the diagram you posted. Look at other pages of the circuit diagram for the same wire and note all the things it's connected to.

Make sure the wire is the correct (factory) gauge or larger. Make sure the hacked separation is joined solidly (solder it if necessary). If the gauge is right and the joint is good, and it still gets hot, then something it's connected to is drawing more current than it should, or there's a short somewhere.

Tracking down excessive current can be difficult. Once you understand all the places that wire fans out too, you might be able to locate the problem by disconnecting portions of the circuit one at a time.

Good luck!

 

well ive been keeping an eye on it since i repaird the wire, its not getting hot to the touch anymore, just a little warm. Its def the stock wire, i guess it was getting hot cause the connection was fubar'd

thanks anyways guys.
