Did you know that more than 60% of car breakdowns are related to the Car Battery, Starter or Alternator?
Assembly of two or more cells for storing electricity. Necessary for starting a car because the generator produces current only when the engine is running.
Faulty Car Battery
If your engine doesn’t crank or cranks slowly,
Put your car in neutral, switch the headlights on and then turn the starter. If the engine does not crank or cranks slowly and the headlights dim noticeably, this could mean corroded battery terminals, a loose battery terminal connection or a defective battery.
First, check and tighten the battery cable connections. Try forcing a screwdriver head between each battery post and terminal whilst someone turns the starter. If this does not help in getting the car started, then you will need to “jump” start your vehicle with jumper cables.
Jump-Starting Your Car Battery
You will need jumper cables and a second car or a battery pack to jump-start your car. Ideally, you want both cars to face each other head-on at about 60 centimetres apart. Depending on where the breakdown happens, this might not be possible. Do your best to get as close to head-on as possible, but do not let the vehicles touch each other. Make sure the car doors will not touch the other car when the doors are opened if the vehicles cannot park head-on.
Make sure both cars are switched off – remove the keys to make certain. Open the hoods of both cars and find the battery terminals. Usually, the terminals on the battery are red or black and you will see a + (red) and – (black) sign on the top. Make sure you can clearly see these signs because it’s essential if you’re going to jump the battery. If the terminals are dirty, use a rag or brush to clean off any dirt or debris until they’re clean and you can see the negative and positive symbols.
Attach the red, positive cable clamp to the positive terminal of the dead battery. Make sure this connection is secure so wiggle around the clamp to get a tight grip if it feels loose. Next attach the opposite end of the red, positive cable to the working vehicle’s positive battery terminal.
Stay over by the working car and attach the black, negative clamp to the working car’s negative battery terminal. Now, walk back over to the dead battery, but do not attach the negative clamp to the negative battery terminal. Instead, attach it to an unpainted metal part of the car like a bolt or the engine block. (Dead batteries can produce hydrogen gas – if there’s a spark you want it away from the battery.)
Start the engine of the working car and let it run a minute or two before trying to start the dead car. If the car won’t turn over at first, wait a few more minutes and give it another try. Revving the car for a minute can sometimes help.
If the car still doesn’t start, then you may need to call for roadside assistance. It could be a number of problems like battery corrosion, fuses or the starter. A professional can diagnose the problem and recommend a repair.
Disconnect the cables in the correct order as disconnecting the cables incorrectly can also damage the vehicle’s electronics. Remove the black, negative clamps and do not let them touch while the other cables are attached to the car. Next remove the red, positive clamps. Do not let the red and black cables touch. You can now close the hoods and pack away your jumpers.
Before attempting to jump-start your vehicle, read your owner’s manual as modern cars have electronic components that can be damaged if not correctly jump-started. This could cause extensive damage and void your warranty.
If the Engine’s ECU (computer box) is damaged your car will be undrivable and the repairs will be costly. If you are in any doubt, rather call a mechanic or roadside assist before jump-starting your car yourself.
If any dash lights come on after jump-starting your car, get your vehicle checked immediately as this could mean that you have damaged an electronic component. A Diagnostic Scan will be able to Diagnose whether it is a serious issue or just the result of a change in electrical supply that needs a reset.Clean your battery terminals with a solution of bicarbonate of soda and a wire brush.

If in doubt, give us a call and we will be happy to come out and assist. If your battery has gone flat on more than one occasion and not the result of an obvious reason like leaving the lights on it may be time to buy a new battery.
