Over charging alt

I have a 2001 hyundia elantra, my battery started bubbling over, checked with voltmeter and its charging at 17.5 volts, replaced the alternator twice and still reading 17.5 while idling. is there any other electrical device that might be interfering with the charging system?

You really need a test drive by a tech. Any shop should be able to do that and give you a firm (written) estimate. It might not be a big deal. Shop around if you need a rebuild, If you need one, ask about their warranty. Believe it or not, a good reference for a tranny shop is the Used Car Manager at the Hyundai dealership. Go in to ask him, not over the phone, and be nice. You're asking for a favor after all. Many dealers do a lot of their work outside the store for reasons of cost. It all depends on the dealership. One will, one won't. Ask.

SOURCE: 2001 Hyundia 300 charging problem.

The 12.2 volt reading to me would indicate a battery voltage only which is fine. However the 11.9 voltage would indicate to me how much voltage the starting system actually used from the battery supply voltage being the differance between the two amounts.I would do the following fully charge the battery one more time and take the same two readings over again and after taking the second reading turn on all the acessorries and if what i am thinking is correct the 11.9 volt reading will drop a consideral amount and possibly stall the engine. If this happens the voltage regulator in the alternator is not working.Take the alternator back, and trade it for a differant one. An alternator needs to be putting out at least 13 to 14.5 volts when under load to compensate for the load.Good Luck and have a good Xmass.

2002 mitsubishi eclipse alternator doesn't charge when cold replaced battery replaced alt had new alt tested checked grounds all good dose this paticular car have a alt relay?


No, cars do not have alternator relays. You say it doesn't charge but checks tested ok, and obviously that can't be true. Test it again. You put a voltmeter across the 2 batter terminals. With engine off, you should get 12.5 volts. While cranking, it should drop to 10 volts. When running, it should be over 14 volts. Cold or hot should make no difference at all, unless the belt slips or something? Why do you think it does not charge when cold? You have not told us everything.

I have a 03 saturn ion won't start. I replace battery and alt and starter and the car want say nothing unless I jump it off what's wrong


You may have a bad or loose connection or bad battery cable. Is the battery still charged up? If you have a voltmeter, check for 12.5 volts or more, then check for at least 9.6 volts when trying to start. If less, charge up the battery, or get a jump and run it for about half hour to recharge the battery.

Replace coil pack


if you mean it will only spin over and run with a jumper check battery & cables--if it shuts off once jumper disconnected shorted battery or bad alternator---if battery more than 3 years old recommend replacement than have reputable shop check charging system (not school kid working at autozone)--or buy yourself a digital voltmeter--12.5VOLTS fully charged battery engine off 13.5 to 14.8 VOLTS engine running alt. good

My 2001 Audi A4 Quattro recently started having trouble starting, sounds like it tries and then finally turns over. Also having issues with my windows power...could this be a batter issue?


I would check alternator charge first....if you have voltmeter, check the charge rate by placing the voltmeter on the positive and negative respectively....it should be 13.8-14.2 volts whilst the engine is running........if it is...then replace the battery as it is not holding enough charge.......if it isnt, then i would suspect a faulty alternator which is not charging the battery enough.......I would also lubricate the window rubbers with with spray silicone, as dry rubbers can also increase the load on the window lifter motors.....as an extra point

I hope this helps....goods luck\
