Hi!!
Your best bet is to remove the battery or the negative battery cable, charge it and drive your vehicle to an AutoZone, Checkers or similar Autoparts store to have your charging system checked. If the engine is running, even if you disconnect the negative battery cable it should stay running, if it dies, the alternator is not working, probably the voltage regulator. If you just bought the alternator, try to take the vehicle to that place so they can check it. If you don't think the car would make it to the auto parts store. Remove the alternator and the battery to have them tested. It is not unusual that an alternator fails when just out of the box. Good Luck!!

First get a volt meter and put on the battery positive to postive negetive to negetive. Start the car you should get a reading of around 14.5 volts then shut the car off wait 15 mins and with the car turned off see what the reading is. It should be around 13.5-13.2 volts if this is the case check for a weak fusable link it will be located between the altenator and the battery on the postive cable. Just follow the postive cable off the battery to the altenator some where in between you will see the link that will most likely need changed. Hope this helps.

Transmission or altenator?


I would say change the alternator out. Start with the simplest and cheapest factor first. Without the alternator keeping the engine running its hard to put it any gear.

2003 taurus lights dimed &suddenly died as if there was no battery. I tried to jump start it but i got nothing but clicking from curcuit breakers by the battery compartment


Yes... Your battery died. But why?

First, leave the cables on longer, a good 10 or 15 minutes. When you hear that clicking noise, it's because there is not enough power available to turn the starter. It means you need more power. Leave the jumper cables on for a few more minutes and you will have the power you need to start the car.

Once the car is started, remove the jumper cables and pull the positive (Red) cable off the terminal on your battery. If the car stays running, get a new battery. If the car dies immediately after pulling the positive battery cable off, then your altenator has gone out. The altenator is the electrical generator that provides electricity to your lights, engine, stereo, AC, etc. It should be putting out about 14.2 volts. Since your car is a 12 volt system, there are a couple of extra volts to spare, which are used to recharge the battery. It takes a lot of power from a battery to start the vehicle. That's why the alternator is there to takeover after startup, plus recharge your battery in the process.

Broken altenator belt peugeot partner 2002


Once your belt snapped all of your cars power was running off of the battery (lights, radio, spark plugs, etc.), then your battery died. Therefore you have no power to turn your starter and apply a spark. Get someone to jump your car, once your car is started allow it to run for a little while to charger your battery back up. Batteries don't allways charge up properly either so you may end up needing a battery, depending on its age.

Car only starts when jumped, quits when brake pedal is pressed


disconnect all the connections to the battery and clean them , also clean all the grounds, check the alternator to engine ground, and engine to body grounds, what you describe is indication of a bad connection and applying the brake is enough to to lower the voltage needed to power the ignition circuit, brake light use a lot of juice

My xr6 wont go!!!!


Hi
It sounds like you need a new battery, the battery may work the radio but wont have enough power to keep the car going,

Alternatively the altenator may not be charging the battery so that could be the fault.

Lastly check the battery connection from the battery to the car body and the wire leading to the altenator and ensure they all have good tight contact.

A loose earth/ground wire can cause this

I was driving down the road, car started acting like it wasnt getting any power so i pulled into a parking lot, put car in park, it idled rough for about a minute, then the battery light popped on and car...


sounds like your altenator is bad. it will bring down your battery. your serpintine belt could also be bad and slipping. my bet is the altenator went bad and your batteru is now bad also. replace both and you should be good to go

05 ford escape wont start. jump started it and it started fine but only runned for a few minutes and the engine started to stall and went off. tried to start it again and it wont turn with the same...


okay try this....talk to your parts store and get a battery load tester, and find out if the battery is indeed dead. My guess is it sounds like the Altenator is dying. they are around 50-100 and can be install by a pro in minutes.
