Mine was doing this also and stalling bad. I found a broken vacuum line going to the DPFE sensor. The problem came back several weeks later. I cleaned the connections to the DPFE and MAF sensors with contact cleaner. Replaced the DPFE sensor, and found I had a broken clip on the MAF sensor connector (probably the actual problem. If you aren't getting enough air flow, or the computer thinks you aren't from bad sensors or connections, it adjusts the mixture leaner.
The alternator must be removed and replaced from the bottom, as with raising the vehicle high enough to work from underneath "safely".
depends on what way you are testing it but you either have a bad connection between the alternator and the battery or your battery is bad and cant hold the charge what voltage are you getting
I just had my alternator replaced (at a shop). They told me the mechanic had to "rip the entire front end off" to get to it.
The Alternator is not putting out enough voltage. If you recently replaced the alternator with a "new" remanufactured alternator that one could be bad to your truck somewhere to get it tested.
$550 at the dealership. The motor has to be raised up to gain enough clearance to get it out of the engine bay.
I always replace the battery when replacing a alternator. They seem to fail hand in hand. Next check the battery cables and alternator connections. Also check to make sure the belt is tight enough. If it is slipping then the alternator wont be charging the batttery correctly. It has to be one of these things. Good luck.
It may be the result of a malfunctioning alternator, or simply a loose alternator belt. When the car is idling, the rpm's of the engine are decreased. This means that the battery is putting out energy, but the engine is not moving the alternator fast enough to refill the charge. When the car is moving, the alternator is getting enough power to keep the lights from dimming.
i had this happen once on an 03 dodge minivan. the alternator went bad and the battery was going dead but had enough power to get the engine started. once i replaced the alternator and charged the battery the gauges worked again. good luck!
Your alternator has either stopped working or is putting out less than 14 volts, therefore not enough charge is getting to your battery.
The show wasn't getting enough ratings, and so they replaced it with a different show
If the bearings in the alternator get bad enough it can lock up.
Same thing happened to me. Replaced the battery & the light went out for a couple weeks; after which it was back on again. This time I took it to the shop & they said the alternator was about to go. I didn't want to "fix" something that was "about to go" so I drove it for about 10 more days before the alternator stopped putting out enough juice to keep the car running or battery charged. Took the car back in & paid to have the alternator replaced. Guess they were right b/c it has worked just fine since. Good luck. It sounds like your alternator is about to go.
