DC volts.

low and high warning zones indicate the normal
operating range. Readings
in the
low warning mne may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since

engine idle. As engine speeds are increased, this
condition should correct itself
as higher engine speeds
allow the charging system to create maximum power.

either warning zone. If you must drive, turn off all
unnecessary accessories.

in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced
as soon as possible.
