I got in my car after work today and it had no electrical power, no dash lights, no warning buzzers, did nothing when Iturned the key to start. Tried getting a boost, would barely turn starter. I replaced the battery it started right up. Drove half a mile and the same thing no electrical power. Finally got it started with a booster, pulled out of parking lot and it stopped cold while engine was running, with no electrical power. All of this was within 7 minutes of repalceing the battery. Had the vehicle towed home. Cleaned all terminals, had to boost to start, ran for 30 minutes at idle, turned off and again. No power to any of the electrical systems at all.
It seems like it may be the Alternator, but it is acting slightly funny for that to be the problem.
Is it the alternator or is there something else causing this to happen.?
There are no lights or AUXillary drains on the vehicle. Is there something that causes it to shut completelydown if the voltage in the battery falls below a certain level? Is there a relay or fuse that Idont know about that may be failing?
Help please, I depend on this vehicle for work and family.
