Battery and Charging System Tester
Although very simple, this tester can accurately
detect the condition of your battery as well as
indicating whether your alternator or charging system
is functioning sufficiently to recharge your battery.
However,
you must adhere to the instructions below
to ensure you will get accurate readings.
■
Operation
Note
: For the most accurate readings always allow
your battery to “Rest”* for a minimum of 12 hours,
i.e. without charging or discharging or running your
engine. Further test battery only with engine and all
accessories and lights turned off. Test alternator /
charging system only when engine is running and
without lighting/accessories turned on.
*”RESTED” = a battery that has been as fully charged as possible,
using your vehicle’s alternator or a 3-stage charger. When using a
charger be sure to disconnect unit from the charger and any type
load for a minimum of 12 hours before testing.
