Diagnosing an Automobile Battery Problem
Article provided by: http://www.powergenixsystems.com/best-car-battery-reviews/
Various vehicle batteries need periodic maintenance as well as require to be serviced on a regular basis
to obtain optimum performance, while others are referred to as [maintenance-free], meaning that they
do not need any repair.
There are several automotive problems that will occur with signs and symptoms that seem similar a
lifeless battery although, with the correct methods and knowledge, these can effortlessly be recognized
ahead of you go out and purchase a new battery pointlessly. For your connivance there is Battery
Tenders obtainable that will preserve your battery in highest condition.
Things You'll Need...
Battery testing meter
Battery load tester
Open end Wrench(s)
Battery terminal washing solution
Battery terminal cleaner [some 100-grit sandpaper works to]
Using a Digital Multimeter to Test Your Cars voltage level. A battery in excellent effective condition
should read 12.66 volts DC between the positive [+] [RED] and negative [-] [BLACK] terminals. This figure
may perhaps be a bit higher or lower based upon its volume and producer, nevertheless should not be
less than twelve volts, in addition to no more than 13 volts. If a battery has altogether charged and
reads a voltage fewer than 12V at rest, you might need to check the battery's water point and top it up if
needed. If the water level in the battery is Good, it may possibly have to be replaced.
NOTE: If you're not certain how to check the water point, have a licensed someone verify it for you.
Now inspect the battery terminals for signs of acid and lose connections. It's very common for corrosion
to arise on the battery terminals. In several cases it is totally evident, however it's yet probable for
decomposition to be obscured between the terminal and the connector. This could lead to not enough
charging, equally a loss of power to the automobile. Take off both terminals and wash them with a
battery terminal washing mixture and a wire brush or [100 grit sandpaper]. Reconnect the battery
terminals and tighten them.
The subsequently step is to check out that ground cable is properly grounded. Follow the negative [-]
[BLACK] wire from the battery terminal to where it grounds to the frame of the automobile. Use the
multi measure to check the resistance between both ends of the cable. A good ground cable will show
zero ohms, or else awfully close to it. Every reading more than 1 ohm indicates a defective ground bond.
Do again this again between the negative terminal and the vehicle's body ground.
Battery load tester
Now we're going to execute a load test. Put the Battery Load Tester between the positive [+] [RED] and
negative [-] [BLACK] terminals. Once this load check is being executed, this gauge will display the
battery's functioning under a actual load. If the battery has been adequately charged and fails the load
test, replacement of the battery is necessary.
Testing the alternator to ascertain if its sending adequate power to the battery. With the multimeter to
test the battery's voltage [as per above] with the vehicle turned off. Now start the vehicle and
investigate the voltage reading again. During the auto is running, the voltage ought to be close to 14.4
VDC. If the voltage is reading the invariable if the vehicle is running as it is while it's turned off, or if the
voltage drops during the automobile is running, the alternator could not be running acceptably and may
perhaps have to be changed. If the alternator is not correctly keeping the battery charged, the
conditions will be vastly like those that come about with a on its last legs battery.
Some Guidelines & Warnings to Be Aware Of!
Filthy or else poorly coupled battery terminals is the most common grounds for battery associated van
troubles. Always cleanse [try a quantity of baking soda and boiling water mixture]and tighten the
battery terminals before going out and purchasing a new battery...Always dispose of lifeless batteries
Make absolutely you wash your palms following handling a battery. [Or better yet dress in gloves].
Vehicle batteries may well be full of sulfuric acid, plus the terminals are generally built of lead. Don't
smoke while servicing a battery. Hydrogen gas may be released from certain kinds of car batteries, and
an explosion may perhaps happen.
It’s an excellent idea to keep your auto and it's battery by the book maintained. There are Battery
Tenders available to guarantee your battery is in best form and will be all set to start your car when you
need it. If you do choose a new battery purchase in a low-cost Battery Tender as well. This will make
sure years of lengthy life from your battery.
