Where abe the fusible links in a 2002 f350

Reprogram what ? Basic electrical problem , not computer . Viewing electrical distribution diagrams an using a DMM - digital multi-meter to test electrical power flow is the way to diagnose . I would start at the main fusible links , fusible link holder . Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine . Under system click on electrical distribution ,then under subsystem click on power distribution . Click the search button ,then the blue link. Looking at the first diagram , i see the main fusible links . I would bet one of these is blown .

Bad cable or connection? Clean posts of battery and reseat connectors, follow power cable checking voltage along the way

Did you check power an grounds at the alternator ? The heavy gage wire on the back of the alternator should have B+ voltage , if not fusible link is blown . The connector ,pin's 1 & 3 should have B+ voltage also . There are videos on youtube on checking charging systems . Do you know how to do automotive electrical testing ? How to use a DVOM - digital volt ohm meter ?
How to Test an Alternator Diagnose Charging Issues

It's a fusible link , do you know what it is ? Here is a youtube video showing location of fusible link . On the video he talks at the vehicle starting , alternator gets power the same way. How to Replace Fusible Link Car won Start If you pull on it an the insulation stretches it's brunt inside .
Fusible Link
In line to the generator, near the positive battery cable
Did you check for B+ voltage at the heavier gage wire on the back of the alternator ? The turn on signal comes from the PCM - engine computer .

How long since a tune-up? Any applicable trouble codes?
Are you saying it went into limp home mode, not much power, or you lost all electricals and it died?
If it is the latter, make sure battery has a full charge and battery connections all good. Check your charging system. Follow one of the positive battery cables, see if it goes to junction block, if so, check fusible links.
Any electrical component that doesn't work, if fuse protected, check that fuse circuit for voltage. Some fuses are hot all the time, some go hot with the key on. Use a test lite.

When electrical stuff doesn't work it is a switch, fuse or fusible link. When you have multiple circuit failures it is likely a bad fusible link. Get out your shop manual for the car and check which fusible link feeds power to these devices; then, test it. If the fusible links all check good, it may be a major connector plug in the electrical harness that is loosing contact. Good luck.

Check the connections on both ends of both battery cables (particularly the main negative cable to engine and body grounds) - clean and reinstall. Could also be connection going bad on the fusible link in the battery + cable, or a faulty fusible link.

You probably have a fusible link that is burned out.

omi n opa, I have never heard of a fusible link that controls everything but in the engine compartment there is a fuse box usually called a power distribution box. Look for a 100 amp fuse that is connected by a large wire on each side. Check the fuse as this will cause all power to be lost in the vehicle. Replace fuse if blown, if not then please, with my apologies, resubmit your question. Good luck with this.

fusible link usually orange blk wire to a black round ten on te wire it will be burnt internally ir right after it .
