96 ford exployer wont stay running new battery but not new and new alternator really new jump start run but will die in 5-10 mins

Sounds like your alternator . Charge the battery , so it will start without a jump. you can check voltage while it's running . Voltage should be 13.5 volts or more

Check the alternator! It may be bad!

Alternator!!! Boost the car, if starts let it run for a few min. Once the car has stayed running for a couple of min, unhook the negative terminal on the battery, if it stays running, the battery is junk. If it dies, the alternator is junk. But this is just my past experience, and it worked.

Never know.

Replace your alternator

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

i might be a bad altinator but i would double check your battery. a bad battery will kill a new altinator. does the battery light stay on? if the battery light on the dash is not on you may have another problem...

Bad Alternator.
After Starting or Jumping your vehicle: Remove the Negative Cable from the Battery.
If the Engine dies or runs really rough it is a bad Alternator.
The Battery Starts the Engine and runs nominal operations. The Alternator runs the Engine after it is Started by the Battery.
If the Engine does not die or runs really rough after removing the Negative Cable, then you have a malfunctioning Battery.

Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

HI there
Try checking a few things first like jump start again and then take off the earth lead only{black} and let it run for 6 minute on idle then turn on the head lights main beam ,,if the engine dies in about 2 minutes then the Alternator isent working full power as it should be pumping out 13.5 volts min and the lights should be bright and stay on... if not you have a Alt problem still like a bad feed to alternator or a bad connection on the battery post or a loose wire from engine to body {earth wire } also check out the relay to Alt ..
Let me know how you get on . RON

keep in mind, your engine use both source of power to run, one from the battery and one form alternator. If the alternator is good, your engine should stay running regardless if the battery is good or bad, the alternator should keep the engine running. It sound like to me the alternator is faulty not charging your battery or keeping your engine running, even though the alternator is brand new does not mean is good. My guess I would take the alternator back and get another one. the reason why your car ran for 25 min and die it has no source of power to keep the sparks going although the alternator should keep the engine running and at the same time charging the battery but is not.

if u cant find any info about the diode try a used alternator should b cheap fix
