I recently replaced the radiator fan and pigtail going to it on my 98 Mustang Cobra. I then noticed the fuse was blown and when I tried to replace it, it immediately blew the new one. Any ideas of what to do to find the short?

You'll need a fan circuit wiring diagram and either a 12 volt test lamp and/or DVOM.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I do have a volt meter, should I just test the female ends on the pigtail?

Sounds like you may have wired that pigtail wrong.

What would be the best way to verify that?

Matching up the old pigtail correctly in the first place.
Does it blow the fuse in the fan is unplugged?
Did it do this before you wired it?

Just two cents and the question. Did this new pigtail come color matched or some aftermarket deal where all wires the same color? If so you have to pay strict attention,

No, they come with all white wires.

Lost one that was on my kitchen counter by Echlin for a headlight - not the point but all wires are black and OE all other colors? Not installed yet because it looks cheap to me compared to the original still workable,

Well when I first cut off the old pigtail I made sure to install the new one matching the same wires so I dont think thats the problem. Furthermore, I was able to get the fan running after installing yet another fuse which lasted all of about a day before being blown. Still having trouble trying to locate a short.

Will this fan spin and coast - use a stick or something all things off keys out? If it's real tight motor COULD be the trouble drawing too much current?

Now you are describing what simply sounds like a bad motor drawing too much current if it's lasting that long. There could be something else tapped into the circuit also.

Was just a wild thought. May not misbehave and be inconclusive. What happened to the original pigtail? Was it all burned from too much heat? You got a day out of a fuse so if this is going to be intermittent I'm looking for "bread crumb" clues as to why? Motor alone may or may not be available separately if and I repeat IF it's deemed drawing too much current,

What's the location number of the fuse and which box is it in?
