Voltmeters usually read RMS on ac volts therefore 120 volts is OK while the indicator is reading peak volts. If unit is operational there is no problem.

I have a 2002 GMC Envoy, Quite frequently my charging light will come on and state that I only have 10 volts coming out and then all the sudden jump to 14 and work perfectly fine


How many mile are on you vehicle ? Have you ever had Alternator replaced before ? You alternator maybe starting to fail , brushes or the voltage regulator .

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

Had my alternator rebuilt, but batteries still go dead.checked alternator shows charging at 11.9 volts then jumps to 15 volts after 2 minutes. is this the alternator


The alternator should be showing at least 15 volts when running! Anything lower would indicate the alternator is at fault, since you say it is showing below 12 volts even for 2 minutes indicates a fault.

there still could be a fault with the battery not holding its charge or something draining the battery like a wire shorting or trunk light staying on that is making the battery go flat!

Code PO401


Exhaust gas recirculation module check:


1. Note the Differential Pressure Feedback Exhaust Gas Recirculation (DPFE) sensor voltage through the scan tool or backprobe the Brown/Light Green (BN/LG) wire of the Exhaust Gas Recirculation System Module (ESM). Voltage should indicate a reading of 0.5-1.2 volts.

2. If the voltage of the DPFE sensor is out of range, low or high, disconnect the ESM and note that the voltage of the DPFE sensor circuit should indicate a reading of 5.0 volts.

3. If the DPFE sensor voltage is out of range connected and the reading shows 5.0 volts with the ESM disconnected, reconnect the ESM and verify that the Brown/White (BN/WH) wire shows a 5.0 volt reading and that the Grey/Red (GY/RD) wire shows to be a good ground, indicating a voltage of less than 0.1 volts. If these circuits check to be ok, replace the ESM due to a faulty DPFE sensor.

4. If the DPFE sensor voltage in step 1 is found to be ok, verify that both vacuum hoses to the ESM have full engine vacuum to them when it's running.

5. With the engine idling, backprobe the Brown/Pink (BN/PK) wire and hold it to ground. This should activate the Exhaust Gas Recirculation Vacuum Regulator (EVR) solenoid of the ESM. The EGR valve should open, the engine should run rough, and the DPFE sensor voltage should climb.

6. Replace the ESM for a faulty EGR valve, EVR solenoid, or DPFE sensor if the DPFE sensor or engine does not respond to ground activation of the BN/PK wire

Ammeter reads 18V with engine running.


I'm assuming you mean the charging voltage indicator. This is an indication of an incorrect charging voltage (too high, should be from 12.5 to 14 volts). This problem is most likely caused by a bad charging voltage regulator. There are two variations of the location of the regulator: 1) regulator is outside of the alternator and located on right side of the engine compartment on the wheel-well, below the starter relay or 2) The regulator is inside the alternator (in which case you'd have to replace the alternator).

Component locator - cannot find the MAP sensor


TESTING-MAP- A vacuum line runs from the sensor mounted high to the intake manifold so it can measure the vacuum in the intake manifold. NOTE: Unusually high or low barometric pressures can generate a false DTC for the MAP sensor. If no driveability symptoms accompany the MAP code, do not replace it.
  1. Connect a MAP/BARO tester to the sensor connector and sensor harness connector. With ignition ON and engine OFF, use DVOM to measure voltage across tester terminals. If the tester's 4-6V indicator is ON, the reference voltage input to the sensor is okay. NOTE: The green light on the tester indicates that the VREF circuit is okay, 4-6 volts. A red light or no light indicates the VREF is either too low or too high.
  2. Measure the reference signal of the MAP sensor. If the DVOM voltage reading is as indicated in the table, the sensor is okay.
    1. Turn the ignition OFF.
    2. Disconnect the vacuum hose from the MAP sensor and connect a vacuum pump in its place.
    3. Apply 18 in. Hg of vacuum to the MAP sensor.
    4. If the MAP sensor holds vacuum, it is okay. If the MAP sensor does not hold vacuum, it must be replaced. Fig. 1: Manifold Absolute Pressure Sensor 84174020.gif

Shop rider sovereign voltage indication. Brand new fully charged


hi Richard,

Does the scooter actually lose power after the 3 leds show ?

If it is losing power then a suggest to try some other batteries to confirm dodgy batteries, check the terminal connections etc.

If it does not lose power then the volt meter is at fault, if you can check the voltage before riding then after it shows only 3 leds , if there is a big drop, check the charger first to make sure the batteries are getting fully charged.

Regards
GeWiz.,
