Measure the voltage across the battery with a simple multimeter. Before starting, a battery in good condition should show better than 9/10 volts approx. Once started the same check should produce a reading of 12.5 - 15 volts, typically 13/14 volts, as the alternator charges the battery by putting a higher voltage in. My 9000 has this basically built into the computer - before starting, it usually shows 9.5+ volts, once started it shows 14+ volts, slowly dropping as the alternator recovers the starting drain on the battery. This assumes no other electrical accessories are switched on. Regards, Danny (a purely hobby site) (UK advert for mobile espresso) (same place, but I can't decide on a name!)
