Interesting!... without diagnosing it myself, I'd say it's the voltage regulator in the alternator... .that is, if YOU ARE SURE the voltage.. 'sure enough it drops and keeps droping'... That's a SURE sign.

Battery is charged and alternator is good but the ignition switch doesnt work unless you boost the car


Hello, you need to go to a shop and have a mechanic test your battery and the alternator, something isn't working right or you wouldn't have to give it a boost in order to start the car.

I hav a 2002 hyndai accent replaced battery and aternator worked fine for 1 day same problem all over is it another bad alternator nw battery also


What exactly is the problem? Is it not charging? Does the battery/alternator light stay on when engine is running? Poor connections can cause no charging, so check all battery, alternator, and starter connections. Make sure all are clean and tight. If still no help, have the alternator tested while on the car and running.

2001 hyundai accent possible alternator or wiring issue


the alternator is not charging
that can be from problem alternator , wiring ,fuse , voltage regulator, incorrectly adjusted alternator drive belt or dead battery
best have an accredited auto electrician check it out by bench testing the alternator and voltage regulator and load testing the battery
loose or dirty /corroded battery terminals will also be a part of the problem
if the voltage regulator is integrated with the ECM , you will need a replacement ECM
BUt get the proper diagnosis done first as that will save cash

Detemined I had a bad alternator on a 2002 Hyundai Accent. After I changed it and got a jump the car would still not run. Should I put a battery charger on the battery to charge it fully?


You should have a qualified shop perform a charging system diagnostic on your car before buying any more parts. With a good alternator and jumper cables connected to a running vehicle, your car should stay running.

Hi. I have an '02 Hyundai Accent. It has shut off 3 times while I'm driving, with no electrical response. I wait it out and it eventually starts up. For the past few months the instrument panel lights go...


Different areas worth checking in order of seriousness are:

  • loose battery cables/terminals - if they are loose, a bump could temporarily disrupt your connection
  • loose battery - the battery itself may be moving around in it's compartment when you hit a bump or jump on the brakes
  • defective alternator - the alternator gives off several symptoms when it's on it's way out. interference when the radio is on, very slow windshield wipers, dim headlights.
Bring the car to any of the bigger chain autoparts stores that feature a free electrical test. They could rule out a bad alternator or possibly narrow down what you should do next.

Replaced battery 4 times


Hello,

there are two things involved. Its either you didn't buy an original battery or the alternator of your car is not very active.

The alternator is suppose to charge the battery, but if the alternator is not supplying full current, it won't charge the battery very well and this will make the battery run down.

I had this problem of recent and I had to change my alternator.

But note that you cannot just change the alternator. Have your alternator tested by a re-wire to confirm if its effective or not. So this will determine whether the battery is not original or if it ran down because it was not charged fully by the alternator.

Good luck.

1991 honda accord will not charge alternator test good


1st check and make sure you have a good ground on the battery. Check the battery. Make sure it passes a load test. It is possible that the battery is not holding a charge. Make sure all alternator connections are connected.
