I don't think there is one- the wiring diagram doesn't show one. But if there is one in that line somewhere, it's easy to check. Just take a test light or a voltmeter and, with the engine off, test for voltage at the big red wire on the back of the alt. You should have batt voltage there even when the engine is off. If you have nothing there, that wire is open somewhere on its way to the battery.

Since the headlights aren't going out during starting, I'd say there's something else going on there. There's a big junction box behind the battery. I think I'd start by going around in there and whacking each of those relays one with a screwdriver handle. There are some fairly major relays in there, and if one is stuck, it may be the reason the alt light stays on and the heads don't go out for starting. We're safe in assuming those two problems are being caused by the same thing. That's almost always the way it works...

it's in the wire between the starter and alternator. looks almost like a splice. about 1 1/2" long and will have a flat side to it.
if it's bad, be prepared... ford only sells the positive cable as a set with the negative. through the dealer it's 75 bucks for the set.
oh, and the link is rated at 175 amps.

well I have ran into the same problem with my 01 and what happened was the battery light came on i checked the wire and ended up pulling out the wire from the connector that goes to the alternator. I will try this and hope that it works I just hate screwing with that big black thing that hooks up to the starter. Thanks for the info

Did this help any for you? I just replaced the pigtail and it ended not being the problem. Battery light still comes on and lights stay on when it dies after excessively low idle.

Before you changed the fusible link did you have these issues: while driving the battery light comes on then comes off after a while (usually no longer than 5 mins); when at a stop the idle drops really low and the battery light turns on and sometimes idles so low the car dies but starts back up very easily; when car turns off all accessories such lights, blower fan, dash lights, etc., still have power; sometimes, though very very rarely, a clicking noise is heard under the dash. Again, I changed the pigtail, since for most people it seems as though this fixes the problem, but with my luck I happen to be the exception. I doubt it is the alternator because this has been going on for months; I'm sure it would have fully crapped out by now. Plus, I have had it checked and the battery is fine. I hope it is the fusible link. How much did it cost? I hate electrical issues!
