SOURCE: charging system

The regulator pack on the alternator has given up, some call it the brush pack also, the regulator is about £10, you will need to rmove the alternator to replace the reg pack, easy job, once fitted with the engine running check the voltage, should be 14.2 volts.

SOURCE: My 2003 mercedes kompressor C200 key is not working!

the key's are special order and they are fairly expensive. Test the voltage in your remote batteries. They should be 3 volts. These systems are very voltage senstive and require a good battery to operate properly. I'm assuming you have the original batteries in the remote now and it is 6 plus years old. These batteries generally last 3 years so it is definatly time if you have not replaced them yet!

2003 Ford ka what colour is the wire for the alternator warning light on dash cluster


There isn't one ! This vehicle relies on serial data communication . The PCM sends an message on the data bus to the microprocessor inside the instrument cluster . The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key ON engine OFF, and stall conditions.
Charging System Warning Indicator
The instrument cluster receives the charging system status from the PCM over the SCP or CAN communication network. The PCM controls the charging system and the charging system warning indicator. The PCM is therefore responsible for turning the lamp off once the system is running and illuminating it under fault conditions (including stall conditions).
How to Diagnose Controller Area Network CAN Your best bet would be to take your vehicle to a qualified repair shop .

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.
Visual Inspection Chart Mechanical Electrical
  • Battery case, posts, hold-down clamp, cables and connections
  • Generator drive (serpentine) belt for condition and tension to make sure there is no slip between the belt and the pulley. For additional information, refer to Section 303-05 .
  • Battery charge
  • Generator pulley
  • Battery junction box (BJB)Mega Fuse
  • Battery junction box fuse:
    • 11 (20A)
  • Central junction box (CJB) fuse:

  • Circuitry
  • Charging system warning indicator
  • Cables
  1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
    • With the ignition switch OFF, the charging system warning indicator should be OFF.
    • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
    • With the engine running, the charging system warning indicator light should be off.
  1. Verify the battery condition. Refer to Section 414-01 .

Have a 1993 ford e350 jamboree that the alternator is overcharging, put new voltage reg. unit on alternator and it seem to fix the problem, but when i went to use it again the charging light came back on...


If you have an engine computer that controls the alternator, you will have to check the wiring from the alt. to the PCM. Also check any fusible links and grounds are often overlooked.
Do you have dual alternators?

SECTION 414-00: Charging System - General Information 2002 E-Series Workshop Manual
DESCRIPTION AND OPERATION Charging System The charging system is a negative ground system consisting of the following:
  • generator
  • integral/internal voltage regulator
  • charging system warning indicator
  • storage battery
  • necessary wiring and cables
The generator is belt-driven by the engine accessory drive system. Refer to wiring diagrams for schematics and locations of the components and wiring.
The battery is a 12 volt direct current source connected in a negative ground system. The battery case is sealed and includes two vent holes to release gases. The battery has three major functions:
  • engine cranking power source
  • voltage stabilizer for the electrical system
  • temporary power when electrical loads exceed the generator output current
The optional dual generator package (7.3L diesel engine only) consists of an upper/lower dual generator system. The upper generator is a 6G 50/110 generator with a 2.49:1 pulley ratio. The lower generator is a 6G 50/110 generator with a 2.32:1 pulley ratio. Thus the upper and lower generators are not interchangeable.
This system is also monitored and controlled by the powertrain control module (PCM). The PCM monitors both the upper and lower generator I circuits to determine both generators' output and set possible fault codes (diagnostic trouble codes [DTCs]). The PCM only controls the lower generator by turning it on or off by opening or closing the lower generator off only when the glow plugs are commanded on by the PCM to avoid possible damage (excessive voltage) to the glow plugs.
Both generators are independent of one another and only control themselves (through their own internal voltage regulator). If one generator fails, the other generator can maintain system performance under light load conditions. Under a heavy load, the PCM should detect a problem, set a DTC and illuminate the warning indicator.
The PCM controls the charging system warning indicator and will command the light on if the PCM detects a problem on the monitored circuits.

Battery light went on while driving and radio went off in my 2003 pt cruiser


Check or have checked the alternator. If it is bad the radio is not the only thing that will shut off. When the battery drains enough the engine will shut down.

My c200 kompressor has a problem with the ESP,how can i fix it?


In your car Electronic Stability Program system included many different sensors (yaw-rate sensor, steering angel sensor, body acceleration sensor, some more) if ESP visit Workshop message appear on your instrument display It's very hard to say witch sensor could be the fault without right diagnose most common faults are either steering angel sensor or yaw-rate sensor might be some other sensors if you replace yaw-rate sensor it's need to be calibrate by diagnose computer, if replace steering angle sensor it's need to do right way otherwise when you tern steering wheel fully left or right it will brake at first time then you have to be replace another one so like to advise you to get right diagnose and repair buy Mercedes specialist if do some thing wrong it's be more cost to you if you get right place to do it only you have to pay once.
