So other day stop at a store came out truck wouldn't start just click click changed start charged the battery fired right up, starter was bad. then my turn signals stop working dash lights dimed radio cut in and out then it stop working got of the road took it out of gear and truck died. then i replaced the alternator and it started an ran for a few then started cutting out and died. I've fixed the comen splice problem, coil, crankshaft sensor with in the last year. all signs pointed to the alternator even took positive off battery and it died right away. now i have no clue to what the problem might be.

 

Have you checked all of your fuses and relays?

 

Check for burned contacts in e power distribution center. Take a look in the service man and trace your circuits with a test light or logic probe (I recommend a logic probe). You can download the manual in the FAQ.

 

DON'T disconnect the battery to test an alternator if it has a computer; the spike created fould fry a computer; that said any time you haver reason to disconnect battery aways do neg first (or "only") with neg connected if pos only (or first) is undone you will almost always get a spark which is itself a "spike" that can screw somethin up
