Flat battery

If your car engine is sluggish when you turn the ignition key,or there is just a clicking sound, there is a good chance that you have a flat battery (not literally! Simply discharged ...). The way to check is to switch on your headlights - if they are dim, or fail to work, the battery is flat.

You can 'bump' or tow start the car using the method explained below, however, you must be aware that this method can shorten the life of your catalytic converter, therefore, if you care doesn't start more or less straight away, abandon the attempt (also, don't use this method repeatedly - get the car fixed!)

With the ignition switched on and the handbrake released, select 2nd or 3rd gear and hold the clutch down. Tow, push, or allow the car to roll down a hill until you are doing 8/10 mph and then engage the clutch - the car should start. You can do this with a 'bump' by engaging the clutch and then immediately disengaging it to allow you to 'rev' the engine.

Perhaps a better method of starting is to use 'jumper leads'. However, before trying this, check the handbook to make sure that it is OK for your model - some engine management systems could be damaged using this method. Also ensure that the other vehicle operates at the same voltage (most cars use a 12v system, trucks use 24v).

Jump leads are simply heavy duty cables with large clips that are used to connect your battery to that of another vehicle ...

First, turn all the accessory switches off on your car (radio, wipers, lights etc.)

 

Then connect the black leads. This lead connects to the negative pole of the battery or to a bare metal part of the engine (min. 18 inches from the battery for safety). If you have an old vehicle check that it is not 'positive earth' before doing this.

Next connect the red lead to the positive battery terminals.

Start the engine of the car with the good battery and allow it to run for a few minutes - your car should then start.

When your car is running, disconnect the red lead first, being careful not to touch it off either the black lead or any part of the car. Finally disconnect the black lead.

If you are unsure what any of this means, do not attempt a jump start - call a breakdown mechanic.

Another method, similar to using jump leads is to use a special jumper battery pack or mains 'quick charger' such as the product shown here.

Stay calm - stay safe!
