SOURCE: Alternator may be overcharging?

Yes It sounds like the voltage regulator inside the alternator has gone wide open .It can also ruin your battery and explode the battery.I would have it hooked up to a alternator tester and just to make sure it's not just your gauge.hope this helps

SOURCE: Alternator may be overcharging?

Well, 18 volts is an issue. And can cook your battery. Proper voltage range is 13.6 to 14.2 volts
The lower the voltage, the higher the amperage so 18 volts is doing nothing as far as charging but is doing alot towards ruining the battery. Have both checked. The battery could have wasted the alternator. good luck. I bet your battery needs lots of water. If so, it may already be trash.

High voltage will shorten the lives of all the lite bulbs in the truck. Lower the brightness of the dash bulbs until you get the alternator fixed so you won't have to take out the instrument panel to get to all of those too.

My A/C system is overcharged on my 2007 Chevy Silverado. How can I fix it?


Take to a repair shop that does A/C

Most likely got issues other than just over charged,
if you played with it yourself, trying to add to the system

Alternator over charging


The alternator is vital part of your car or truck's electrical system. When the vehicle is running, the alternator provides a constant charge to the battery, as well as to other accessories. Without the alternator, the battery will eventually discharge. However, if the alternator isn't working correctly, it may send too great of a charge to the battery, which is known as overcharging. This condition is dangerous to your car's battery and electrical system. You can test to see if the alternator is overcharging, using a simple voltmeter. Start your vehicle and open the hood. Be aware of the moving parts within the engine compartment, as you do not want to get your hands or tools anywhere near them.

  • 2 Locate the vehicle's battery. It may be obscured by protective shields, the air filtration or intake system or a fuse box. Whatever the case, you need to remove everything that covers the battery. You must have access to both the negative and positive terminals of the battery.
  • 3 Turn the digital voltmeter on and adjust it to the proper settings, if necessary. The voltmeter must be set to "DC" and 12 volts.
  • 4 Connect the clamps or leads of the voltmeter to the battery. You must connect positive to positive and negative to negative. The positive lead is usually red or yellow, while the positive terminal on the battery will be marked with a plus sign. The negative lead on your voltmeter is black, while the negative battery terminal is marked with a minus sign.
  • 5 Examine the voltmeter. If you've hooked it up properly, you should see a reading somewhere between 13.6 volts and 14.3 volts. A reading higher than 14.4 volts warrants further testing by a professional. If your alternator is found to be overcharging, you will need to have it replaced.

    Air conditioner compressor runs - freon is up to proper level....not cooling??


    BOTH High and low readings should be checked to have a better idea of what is going on with an AC system but based on the limited information… the compressor is not engaged or is not pumping. Below are some things I would check;

    1. Check the high and low gauge readings with the AC on & set on MAX/Recirculate, middle vents with the engine at 2,000 RPM’s, blower speed on high.

    2. Check the vent temperatures with a thermometer from the middle vents, far right & far left vents?

    3. What is the outside temperature at the time the readings were taken?
    4. Check to see if the condenser fan blowing strong?

    5. Notice if compressor clutch is cylcling excessively.
    Could be overcharged, not enough air going across condenser fins, compressor not pumping sufficiently… BOTH gauge readings are really needed to get a better idea.
    Below are normal car AC pressure readings with 134A.

    Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

    Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

    Normal high side reading ranges from 200-350 PSI

    Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor

    Thank you for using fixya and good luck, keep me posted. Be glad to help you get your A/C running again soon.
