Question about 1992 Volkswagen Jetta

My 1992 Jetta is discharging when not in use. It has a new battery and the alternator puts out 13+ volts when tested at the battery. What is the most likely short and how do I check for it?

the most common cause for discharging like that, is a faulty switch on either the glovebox light, or the boot light. interior lights are easy to spot if they remain on, but boot and glovebox lights can stay on without being seen. try taking the bulbs out of the bootlight and the glovebox for a few days and see if it helps. if it does, replace one bulb to find out which is the problem.

other possible power drains include alarm systems, radios, and various alternator faults.

check the lights first, and if you need more help to find the problem, feel free to ask

71 c10 not staying charged... new battery alternator fuses good and new voltage regulator

Maybe it wasn't running long enough to charge up the battery?
Stop trying to jump it, when you are having problems with it dying, take the battery off and have it charged. And/or buy a $20 voltmeter to see what the battery shows. If it says less than 12 volts, it is discharged, and needs charging. A good battery that is not run down should have at least 12.5 volts. A new battery that is charged should have very close to 13 volts, maybe 12.8 volts.
When you have the truck running, check the alternator for charging. You put the voltmeter right on the battery and check it again. This time, with truck running, battery should show at least 13.5 volts. That shows the alternator is working. A good alternator will put out about 13 or 14 volts-the regulator will keep it from going any higher to prevent problems, like a melting battery or electrical parts burning out.
I would say get the charging system working right, then address the problem of dying at stop lights. That could be a carburetor problem, if the alternator is working.

What happens when battery light keeps coming on 2003chev trailblazer

Voltage low usually alternator/regulator not working and battery is discharging. Put voltmeter on battery when running should be 13 to 14.8 volt if not replace alternator and 13 is low should be about 13.8. A fully charged battery is 12.6 not 12.5or lower

We have replaced battery in car while driving and then comming to a stop it shuts off. Put in park then restart it runs stop again it stops again. What could this be? Car was running fine before.

Check your alternator. Get a Voltmeter and test voltage at the battery with the vehicle running. It should be about 13 or 13.5 volts. Then check it at the alternator. It will be the red cable at the back of the alternator (the side not by the belt) It should be 13 or 13.5 volts. If the battery reads less than 13 then check the alternator. If both readings are low but close i.e. battery=11.4 and alternator=12.5 then the alternator needs replacement. However if your readings are alternator 13.3 and battery 11.5 then you need a battery cable between the alternator and battery. Hope this helps.

Battery light is on.

I would say it would be the alternator. Most local parts stores can test the alternator. But when the battery light is on, it's usually the alternator. I would check the fuses for a blown one.

When the Jeep was new the volt meter read 14 the volt meter reads 13 volts with a one year old battery. Since the battery is a 12 volt battery should there be any concern that the volt meter...

It needs to be looked at,hook a volt meter to the battery,and start the engine,turn the ac on high blower,and the head lights on,the alternator should be putting out 13.65 volts to 14.25 volts,if it is any lower than this,replace the alternator,now,if the reading is not the same as in the vehicles volt meter,then the cables,positive and negative need to be replaced,the cables get old,and corrode on the inside and break down,they do not carry the current as they should.Shuold you decide to replace them,go with a larger diameter cable,both positive,and negative.
