An automotive or auto battery charger rarely goes incorrect. A battery charger doesn't contain whatsoever moving parts and is simply a device that transforms mains alternating electric current (Air-conditioning) into direct current (DC) at a much reduced voltage (usually 12 volts). The internal wire windings that transform the electrical electric current from Ac to DC are not DIY serviceable components and, unless you lot are a qualified electrician, it's not advisable to tamper inside the auto bombardment charger. However, if yous detect that your charger refuses to charge your car battery y'all can hands repair the fuse in the mains plug and the fuse on the battery charger, as information technology'southward highly likely to be i of the fuses that take blown.

Check Battery Charger Output

Step 1

Check that your bombardment charger is definitely non producing electricity. It's oft the bombardment that won't charge and non the battery charger.

Step 2

Plug the charger into the mains electricity socket. Turn on the charger.

Stride iii

Apply a voltmeter to decide if the battery charger is producing electricity. Place the terminate of the red wire from the voltmeter onto the metallic clamp on the end of the red cable from the bombardment charger. Place the terminate of the black wire from the voltmeter onto the metallic clamp on the end of the black cable from the battery charger.

Read the voltmeter brandish. If information technology reads but over 12 volts, the charger is working (and then the outcome is your battery). If in that location'due south no reading, the charger needs repairing (so check the fuses). You may sometimes get a minor reading of perhaps one or 2 volts. This is due to electrical resistance and doesn't mean your charger is producing electricity.

Replace Plug Fuse

Step 1

Remove the plug from the main socket. Remove the cover from the plug using a screwdriver. Before changing the fuse, bank check the three wires are securely connected to the terminals. If any are loose or asunder, it explains why your charger doesn't piece of work. Tighten whatever loose connections using a screwdriver.

Step 4

Replace the cover on the plug. Tighten using a screwdriver.

Insert the plug in the socket. Turn on the charger. Echo the voltmeter exam. If you get a voltage reading of simply over 12 volts, you've successfully repaired your bombardment charger. If there's no reading, plow off the charger and unplug information technology. Follow the steps in section iii to replace the fuse on the battery charger.

Replace Battery Charger Fuse

Step 1

Locate the fuse on the battery charger. It'south commonly on the front, inside a clear plastic cover. You too unremarkably find i or two spare fuses in the aforementioned location.

Step 2

Open up the fuse encompass using your fingers, or gently insert a screwdriver in the clip and pry it open. Remove the fuse from the fuse holder. Bombardment charger fuses tin can generally be pulled out using your fingers, but if you accept problems only carefully ease it out using the screwdriver then remove it using your fingers.

Step three

Put a replacement fuse into the fuse holder. It pushes into place. Shut the fuse cover. Insert the plug into the mains socket and turn on the battery charger.

Test the output voltage from the charger. If the voltmeter has a reading of merely over 12 volts, the battery is repaired. If there'south no reading on the voltmeter, the battery charger has a problem with the internal wiring and y'all need to become it repaired by a specialist or go a new charger (probably cheaper).
