I've done some searches of Tech and Archives on "short(s)", "electical" and "multimeters", but still have some questions ... I'm really a Noob with electrical systems <img src="/forums/images/graemlins/shiner.gif" alt="" />

My ECU keeps throwing a CEL; code 0440 Evaporative Emmissions System. Truck runs fine (or seems to <img src="/forums/images/graemlins/rolleyes.gif" alt="" />) but that CEL is damned annoying.

In any event, I took my rig to the stealer to see what they could tell me about the code. After plucking $45 from my wallet they told me there was a short in the wiring and that the harness would have to be replaced ... $300 <img src="/forums/images/graemlins/ignore.gif" alt="" /> <img src="/forums/images/graemlins/shame.gif" alt="" />

With a "short" I guess I'm looking for chafed, melted or burnt wires?

Is there a way to find a short with a multimeter? I bought one and am currently reading the manual to try to figure it out <img src="/forums/images/graemlins/drunk.gif" alt="" />.

How do you fix a short? Assuming it is a simple chafe of the wire - would I just put electrical tape around it and call it good or is there a better way / product.

I read in one thread about soldering the wires together and heat shrink wrapping the joint. Is this the preferred method?

What tool do you use for soldering and what material to you use as solder (not sure if my terminology is correct here)?

Any insights you could give me would be greatly appreciated.

Thanks! <img src="/forums/images/graemlins/kewl.gif" alt="" />
