Got to check the connections. The connections at the battery as well as at the solenoid/starter. There may also be an ignition switch problem but this would likely cause other problems as well. The connections should clean and tight and if your battery terminals are an after market type the part where the cable goes inside the terminal needs to be checked and cleaned if it can be disassembled. The starter solenoid is usually mounted on a fender close to the battery in the engine compartment and are notorious to cause failure and often times intermittent failures as well (one time it works another time it doesn't).
I have a 1997 ford expedition that the alternator is not charging the battery. Had the alternator tested and it was good the battery is new. Cant find the fuse for the alternator does anyone know where it is?
Check battery connections, check alternator out put. Exc.
more than the alternator diode is bad have the alternator checked
The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
the 20 amp alternator field minifuse is loosley connected below the lower 175 amp alternator megafuse on the firewall next to the battery.
battery and or alternator are shot, check alternator by starting the car, and removing either the positive or negative battery cable,,, if the vehicle continues to run the alternator is good.
battery is dead
Possible bad alternator.
A bad alternator will have the effect of draining the battery, resulting in dim lights, trouble starting the car and the like. It would be best to replace the alternator as soon as possible and possibly obtain a new battery. This may vary depending on how much the bad alternator has drained it. You can get your alternator and battery checked any time at Auto Zone.
check the battery or battery cables or the alternator or starter
