Your alternator should putting out 14-14.6 volts with engine running.If you only have 10 volts with engine running then your alternator is not charging take alternator back for a replacement.

what you need to do is check the altenator for voltage it should be between 13 and 15 volts this is easily done with a standard volt meter check it at the altenator witch is located right on top of the engine on the back of the altenator there is a thick red wire that is where you want to put the positive and just put the black wire of the volt meter on the case of the altenator and check the reading it sounds like the altenator is bad there is also a fuse you should check your owners manual for location of the fuse also have your battary checked this should help ant questions just ask me

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.

Jaguar 1999 XJ8L battery won't start unless I


This problem could be a number of things. Let's start buy checking for light bulbs that are not going out when car is shut off, such as under hood lid, under trunk lid, inside of car that are hard to see, such as lights that usually stay on till you leave car but normally go of after a few seconds. You can tell buy waiting a while, they will be hot to touch. If this is so this is your problem.
Next check alternator, get an ohm meter, start car, set ohm meter to about 20 volts, and with car running put ohm meter cables red to positive of battery and black to negative of battery. This test should let you know if alternator is working and good if reading is between 13- 14.50 volts, if you do your alternator is good,if not alternator is problem.
Next check the battery with ohm meter. With ohm meter set the same way to 20 volts, and car off , put red lead to positive post and black lead to negative post . Your reading should be 12-12.50 volts. If reading is low 9-10 volts then the final test would be a load test. You may have to go to your mechanic, or a battery dealer for this one because not everyone has a load tester. This test will tell you if you need a new battery. They will know right away. Your problem could be a bad battery. All the above tests are for DIY. If you are not able to perform these tests yourself then go to a battery dealer they will do tests for you. GOOD LUCK.

I have a 99 Pontiac grand am gt that has a good alternator that isn't charging the battery. The wires are connected correctly and the connections are clean and the battery terminals are clean as well....


Have you taken the battery to autozone or someplace and had the battery tested? I would find if you know the alternator is good it must be the battery itself. Might want to try that if you havent already. Good Luck Bro~

The first question for you is, What is the charging output for the altenator at idle?? If less than 12.3 volts, replace altenator. Typically, the altenator gets tested at 2500-3000 rpm on a bench tester. Your problem may be in the low rpm output range.

Low volts light stays on


new altenator or junkyard one.if new return it, if junkyard just ignore light as its odds on they will not change it .the red light is caused by the difference in the voltage between input and output voltages .Quick test --start engine and run at 1500rpm disconnect battery and turn everything electrical on and if engine stops then change altenator if it stays running then altenator is OK
