Battery light came on this AM on my way to work....2004 F350 6.0

since the radio is resetting, i would first check the battery terminals. the radio has to power inputs, so if its resetting then your losing both at the same time. one wire more or less comes directly from battery, its the memory wire to get a presets and times.

DID YOU CHECK OR REPLACE YOUR BATTERY SENSOR, LOCATED UNDER NEATH THE BATTERY HOLDER, GOOD LUCK

Sounds like you have a weak battery. It doesn't take much power to make all the lights work but you need a lot of current to start the engine. You can test the battery by looking at voltage across the terminals when you try to start the car, if it's less than 12 volts your battery needs to be replaced. If your battery is more than 5 years old it should be replaced anyway. Good luck, let us know how it goes.

It sounds like a bad alternator. Put a voltmeter on both the negative lead and positive lead of the battery and it should read above 13volts

Sounds like you have a bad battery. Check the date on the battery, if it is original it is probably time to replace it. Often times the radio and lights will still work when the battery is low because they take less power than the starter. If the battery is less than about 4 years old you may be looking at a starter on its way out. But it sounds more likely that it is a bad battery.

Voltage is too low. It should not be less than 12. Re-charge and load test the battery then check to make sure it's charging properly.

batterys can look great on a guage and have no juice try getting a boost and also check the master and assessory fuses under the hood in the fuse pannel
sounds like you blew a master fuse

That means it is not alternator, it was battery discharged. Have both checked for free at autozone store. Maybe you need to clean/replace heavy power cables coming out/to battery and out /to alternator, as the deposition reduces the current
Also check the alternator belt for tension by twisting (less when 90 deg) or pressing (1/4 inch freedom)
Hope that helps
Good Luck

sounds like your alternator. if you have a multimeter then turn on your car and turn your headlights on/ac and heater fan on high/wipers on and blinkers on. once they are all on hook the meter to the battery and if it reads less then 14 volts then the alt is bad. or you can just take it to a shop and have it tested.

your alternator is not charging correctly and your battery voltage got low thats why all the other lights came on .you need to replace the alternator please rate this answer thank for choosing fixya.
