Quick check is to remove a battery cable while the motor's running. If the motor stays running when you pull off the battery cable, the charging system is functioning properly, if it dies then there is a problem with the charging system. Don't leave it off long, as this test is stressful to the circuit. You can test the voltage regulator by putting a volt meter across the battery posts to verify voltage. A fully charged 12 Volt battery should show slightly above 12 volts DC. With the engine running and the volt meter hooked to the battery, the charging system should be showing around 13.8 volts DC.

I have a 2003 C180 Kompressor - 4matic. Im getting a replace alternator sign but its seems to work fine but im geting also increase in electricity in the car and even disconects and reconects while im


The voltage regulator in the alternator has probably failed. The AH rating of the battery has nothing to do with it. This is why I would never own a MB, too many gadgets that cost a fortune to fix when they fail.

The low beams on my pilot are blowing, if that makes sense. My high beams will work fine, Ive had to replace the bulbs more frequently than I know I should have to. Do I need a specific bulb or a higher...


This was a fairly common problem for older cars. It was usually caused by a bad voltage regulator, that allowed the voltage to get too high. I recently fixed the same problem on a 1986 Dodge.
I haven't heard of this on newer cars. The newer cars have electronics can be very sensitive to voltage spikes.

Anyway, I still suspect that the high voltage is the problem. You can have the voltage checked, but it may be intermitent. Most modern charging systems have the voltage regulator integrated in the alternator. An alternator can be pretty expensive to replace, just to try it out. You could have the alternator checked at an auto parts store. Or you may have to have it checked by a auto tech/dealer.

Another possibility is the type of bulb you are using. I replaced the bulbs on my Escape with Sylvania Silverstars. I blow them pretty regular; every 6mos or so. This is fairly common with high output headlamps.

My battery light is on all time on the dash, why?


There is a fault in your battery or the alternator or voltage regulator. It is most likely the alternator as in this model the voltage regulator should be built into the alternator. You can remove the alternator and have it tested at Auto Zone or Advance auto or Pep Boys, most major auto parts stores offer to test them to make sure that is the problem. Since you would have to trade in the old one as a Core to get the new one it only makes sense to have it tested first anyway.

Alternators not charging changed alternator and battery checked main power wire its good where does the small red and green wire go to off the voltage regulator


the red wire is the power, the grren wire is your signal wire. the green wire sends the signal from the regulator to the ecm to tell it when to cycle the alternator on and off. you could have a faultyy regulator or signal wire causing the malfunction. the wires join the main harness after the regulator.

Where is locotated the voltage regulator in 2004 Toyota Highlander. I want to replace the voltage regulator in my 2005 Toyota highlander and I don't know how I can locate it.


the voltage regulator on this along with most newer vehicles is located inside of the alternator. this is not replaceable as it is internal unless you get an alternator rebuild kit. if helpful please leave positive rating.

If the blower motor is bad ,this would happen ,the setting 5 gives it full voltage,but on the lower speeds lower voltage,and if the blower is bad,it will not run.
