My 1990 camry is charging 14 volts but will not turn the charge light out on the dash, allso the headlight indicator and brake light are on, i allready changed the regulator

Get a volt meter, start your car and see how many volts your car is producing while running. Should be around 14 volts. May want to watch the meter for a while since your electric seems to fluctuate. Most voltage regulators are internal of your alternator. If you are getting a lot more or less than 14 volts while running, replace the alternator. If it is not charging, voltage will drop as vehicle runs, until battery is dead.

Not sure I follow your problem.
The alternator puts out 13-14 volts at idle but very few amps. If you turn on the headlights at idle the voltage may drop to 12 until you raise engine speed. The amperage goes up with engine speed.
Is the battery voltage at least 14 when the engine speed is 1500RPM or more ?

check for voltage at the battery with the engine running. You should see 14 plus volts. Now turn on the lights, bower motor, and whatever else you can to put the maximum draw on the battery. If the voltage drops below 13 volts the alternator is bad.

Hi there.
You must have a drain some where.
Make sure the brake light are NOT staying on. if they are, it will drain the battery. this is due to faulty brake light switch.
I think the ESP light is related to the brake light switch.

sounds like an alternator not charging. You should have 12 1/2 volts with engine off and 14 1/2 volts with engine running if alternator is working.

A fully charged battery has about 12.6 volts but the battery voltage will increase to a point that is usually between 13 to 15 volts when the engine is running with a properly operating alternator. I find most charging systems seem to hold the voltage in that 14 to 14.6 volt range depending on how many electrical devices such as a/c, headlights, etc.are on at the time which can pull the voltage down a bit.

Generally if charge light is on, alternator has a bad diode in it. This lets the charged battery lose its power by flowing in the reverse direction. It sounds as the alt., is either not connected right or is swtill bad

With a volt meter and the engine at idle, check the voltage at the battery.It should always be just over 12 up to 14 volts. At idle with no accessorys on (lights, fan, radio ect.) The voltage should stay just over 12 volts. As you turn on all the accessorys the voltage should rise up to between 12-14 volts.
Also, a new battery needs to be fully charge before use. Most new batterys sit on the shelf and lose charge. My last new battery needed 8 hours of chargeing to be fully charged.
I hope this helps.

It is possible that the extra demand placed upon the charging system finally blew the alternator.
You need to have the charging system checked,,or check the output yourself with a volt meter (should be around 14-15 volts) test must be done with the car running.
If the voltage reads up to 14 or 15 volts then it would indicated a short in the dash control circuit.

check the charge rate should be 13-14 volts, if lower check for alternator drive belt condition/tightness if ok replace alternator
