1 Battery completely dead. check and replace if bad.
2. Check all battery cables at both ends. Clean and tighten.
3 Check all fuses and circuit breakers
4 Check alternator output. not over 13 volts replace check alt belt tighten
B4 buying a batt or alt make all the checks and test after each one for power/start
Battery light on ! alternator isn't charging . Test the alternator electrical circuits .Main cable on the back of the alt. should have B+ voltage .Pin # 3 at the connector on the alt. should have B + voltage - fuse F10 10amp under hood fuse box supply's B+ to pin #3 . Pin's 1 & 2 at the connector go to the PCM - engine computer . This is a computer controlled charging system . Ford PCM controlled alternator testing
Yes, If you have a volt meter, jump and start engine, with engine running you should have approx 13.5 to 14.2volts that would tell me that batt is getting charged when engine is running. you said new batt would not hold a charge, I would be thinking about a parasitic draw(small amount of power) that in time will drain batt. things to look for are glove box lights, under hood lights that dont turn off. one easy way too see if you have a draw is to disconnect one batt cable, now use a regular (12volt non-self powered) test light and touch one end to batt cable and the other to empty batt terminal, with no light switches on and doors closed, this test light should not light and if it does then you have a drain on batt that will kill it say overnight.
sounds like you either have a loose wire that is preventing the alternator from charging the battery and keeping you going or the alternator has a bad diode. Take it to an auto parts store and have them test both battery and alt while the car is running.
if when you jump it starts its your batt if if keeps dying it your alternator the clicking sound is your statrer which means thats good try the batt when you buy a new one it will have a warranty soo if it dies because the alt you will get a new one batt for free (the alt charges the batt)
your charging system is not working,so your car is working only on batt. power,when batt.gets weak car will cut off! good chance alter nator is defective! check alt.elect. connections at alt,if con.are good its alt.
