At one time or another, everyone may have problems starting their MINI.

The first place to look for trouble in your starting system is your battery. The battery is perhaps the most important electrical component on the car, and due to its Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement and nature, is perhaps one of the most troublesome. Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement doing anything drastic like replacing your starter or looking at your fuel injection ECU, you should make sure that your battery is in good condition.

Begin by checking the voltage on the battery posts Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement a voltmeter. Place the meter's probes on the posts of the battery, not the clamps. This will give the most accurate indication of the voltage in the battery. A normal battery should read a voltage slightly above 12 volts with the car sitting still, and no electrical devices on. Don't worry about the door lights, they hardly make a dent.

A typical reading would be in the If the reading is 12 volts or less, then Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement battery needs charging or needs to be replaced with a new one. To be certain, you Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement take your battery to your local auto parts store for testing. When the car is running, the alternator should be outputting anywhere from about If you don't see any significant change in the voltage after you start up the car, then your alternator could be faulty.

The engine and transmission are mounted to the chassis using rubber mounts. While great for the suspension, the rubber mounts make lousy electrical conductors. To compensate for this, there is an engine ground strap that electrically Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement the transmission and engine assembly to the chassis, located inside the Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement compartment.

Check the strap to make sure it's not corroded or damaged. Make sure that you clean both ends of the strap and the areas that it mounts to on the chassis. With all electrical connections, it's a good idea to clean the area that you are mounting to with rubbing alcohol, and also to sand the area lightly with Mini Cooper R50 R53 R52 2001-2007 Banner Power Bull 50Ah Battery Replacement fine-grit sandpaper or a wire brush.

Doing so will remove any dirt, grime, surface rust, or other corrosion that may interfere with creating a good electrical connection. While you're at it, clean up the battery terminals as well in a similar manner.
