Should be a bulge or something in the wire,that's the link,If the wire is hot ahead of it and not behind it ,it's blown.If you have an ohm meter,you can probe ahead and behind it to see if it has continuity.You really need a test light with an "ice pick" type probe and an alligator clip on the wire to catch ground,then you can stick the wire through the coating and see if it's got power with out skinning it or going to the next terminal.They can be bought pretty cheap and you will use it a lot.Little multimeters are also cheap($10or so)and the can check voltage and ohms,just don't put voltage to it when it's set on ohms or you will fry it.You can pick these up at any cheap auto parts or place that sells electrical supplies,and for times like this they are priceless.
Hey greyghost,I don't blame you,electrical problems can be a sob,and without the information and gadgets needed,it can give you a big head ache.The bad thing is that every year it gets worse,more electronics.Now they have vehicles that change cam timing or automatically stop for things or the new Lincoln that lowers its height at high speed,all electronically.Imagine blowing your engine or stopped in the middle of the road and can't move,or dragging on bumpy roads,all because of a short or broken wire.People are always saying "change is good" (mostly political a$$ holes),but 90% of the time for me it just means more grief !
How about the cars that parallel park themselves. Actually, what I am doing, is going simpler....but you cant make an omelet without cracking a few eggs
