Typical Questions & Answers:
Q. Why do I need the BSU?
A. While the IDS diagnostic system is in use on a vehicle there
can be a substantial drain on the vehicles battery, which can
cause the battery to loose charge very quickly and stop the
diagnostic process. In the worst case this can irreversibly
damage the vehicles electronic modules
Q. Can I use a battery booster pack
to support the battery?
A. A booster pack can only provide support to the battery for
a very limited period of time before it starts to loose charge.
The type of batteries used in booster packs are designed to
provide high output over very short periods of time (30 seconds)
not the length of time required to carry out diagnostic routines,
re-programme modules or bleed ABS brake systems. The use of
an ordinary battery linked to the vehicle with ‘jump leads’
is not a safe option as there is a risk of arcing which could
cause damage to electronics or an explosion. The BSU is fitted
with a number of safety devices to prevent damage to the operator
and vehicle.
Q. How does the BSU work?
A. The BSU matches the draw on the battery from the vehicle
to maintain the battery voltage.
Q. What happens if the power draw on
the battery is greater than the output of the BSU?
A. There are occasions where the power drawn from the battery
is greater than the BSU can supply, these instances are for
very short periods of time. The BSU will supply up to its maximum
output and the vehicles battery will provide the balance.
Q. Is the BSU a battery charger?
A. No the BSU only supplies power that the battery needs, it
will not charge the battery.
Q. Can I use a battery charger to do
the same job?
A. The BSU provides a ‘clean’ regulated voltage, which will
not have an impact during a diagnostic procedure.This cannot
be guaranteed using a standard battery charger.
