Troubleshooting Car Battery

These section covers all possible battery related problem in your vehicle.

Its a useful Car battery troubleshooting guide which you can refer to solve battery related problem with your vehicle.

Battery problem in your car is sometimes very easy to identify,but on some cases you just ignore the battery issue,when its actually the problem with your vehicles battery..At our Autogarage Repair center,we have seen new batteries coming faulty.

Sometimes the battery shows same voltage(12volt),but still its faulty.This is because battery getting old.A basic life of car battery is approx 2 to 4 years.Its not that it will not perform after 4 years but mostly these batteries are to be replaced,to make your vehicles electrical system upto mark.

Regarding replacing car batteries i will say.Always buy branded batteries if possible.Why because local aftermarket batteries are made up of weak internal cells.Cells are inside the battery,which actually hold the charge.If the cells are weak,then battery will not remain charged or loose its charge in few hours.

A branded battery is bit costly,but you will really enjoy its performance.Also if in case a new brand original battery gets faulty,you have warranty on it.So there is no risk of investing in original genuine battery product.
As compared to aftermaket local batteries,they don't come with warranty and there is just few months guaranty provided.
Some times these aftermarket low cost batteries don't get completely faulty,but there performance will be very weak or it will not support your vehicles system.

Here in these section, we have mentioned types of Auto battery related problems with there respective solutions to troubleshoot the car battery problem.

Also details are provided to maintain your vehicles battery,for more battery life.

Charging system problem on Chrysler LHS car?

Troubleshooting Chrysler LHS car.
Battery not holding charge.Car headlights flickering or getting dim.
Starter not engaging or alternator not charging car battery.
In this cases the car charging system needs to be tested.
On that basis the troubleshooting procedure is as follows :-----


It should read low 14 or high 13 volts when it work right.

The main components of the alternator are the rotor, stator, rectifier, end shields and drive pulley. Direct current is available at the output "B+" terminal.

Alternator output is controlled by voltage regulator circuitry contained within the power and logic modules of the Engine Controller.

CIRCUIT OPERATION 
The charging system is an integral part of the battery and starter systems. Since these systems work together, any diagnosis and testing should be done in conjunction.

The charging system is protected by a 12 gauge fusible link located in the A11 circuit. The A11 circuit is connected to the battery feed BUS bar of the power distribution center.

The generator is case-grounded through its attaching bracket. This generator uses a voltage regulator internal to the Powertrain Control module (PCM) .

When the vehicle is running battery voltage is applied to the generator field terminal through the A142 circuit, on all engine applications. This circuit is controlled by the contact side of the Automatic Shut Down (ASD) relay. The ground, or voltage regulated side, of the generator field is controlled by the K20 circuit. Circuit K2O connects to cavity 4 of the PCM.

When there is current present in the field, and the rotor is turning, the stator in the generator produces a B+ voltage that is supplied to the battery through the A11 circuit. The A11 circuit is connected to the output terminal of the generator and to the BUS bar in the PDC .

Grounding for the system is accomplished at the battery negative terminal. These grounds go to the engine and body

Here some test for you.

graphic
  • Complete test connections as shown.

  • Remove air hose between engine controller and air cleaner.

  • On non-turbocharged models, connect a suitable jumper wire from green (R3) terminal to ground. Do not connect blue J2 circuit to ground.

  • On turbocharged models, connect a suitable jumper wire from green R3 leadwire on dash side of black 8 -way connector to ground. Do not connect blue J2 lead of 8 -way wiring connector to ground.

  • On all models, connect battery ground cable, then start engine and operate at idle.

  • Adjust engine speed and carbon pile rheostat to obtain 20 amps in circuit, then check voltmeter reading. Reading should not exceed .5 volts. If a higher voltage drop is indicated, inspect, clean and tighten all connections in circuit. A voltage drop test at each connection can be performed to isolate problem

    • Ensure battery is fully charged

    graphic

    Ensure battery is fully charged.
    Start engine and allow it to reach operating temperature.
    Clean all dirt and corrosion from a small spot on alternator housing.
    Turn on the following:

    Headlamps on high beam.
    A/C system.
    A/C heater blower switch to high.
    Radio.
    Rear window defogger.
    Connect the positive lead of a voltmeter with a millivolt scale to alternator housing attach negative lead of voltmeter to battery negative post.
    Voltage drop should not exceed 0.2 volts. If voltage drop exceeds 0.2 volts, remove alternator and thoroughly clean surfaces between alternator and mounting bracket
    Ensure battery is fully charged.
    Check generator ground path using an ohmmeter. Resistance should not exceed .3 Mega ohms.
    Connect positive lead of an 18 volt voltmeter to positive lead for generator (B+) output terminal.
    Connect negative lead to positive battery post.
    Connect an engine tachometer.
    Place transaxle in park position and apply parking brake.
    Start engine and allow to idle for ten minutes.
    Operate blower motor on high speed and turn headlamps on high beam.
    Increase engine speed to 2400 RPM and observe voltmeter. Voltmeter should not exceed 0.8 volts.
    If a higher voltage drop is indicated, clean and tighten all connections between generator and battery.
    If voltage drop is as specified, system is operating correctly.

    This details will help.
    Thanks.
