This service guide applies to most portable style
SCR regulated charger designs but not all. This
service guide does not cover railroad or heavy
industrial styles of chargers. Please contact the
factory for assistance if there is doubt regarding the
appropriate service guide for a specific model of
charger.
The battery charger is, at most, one third (1/3) of the
complete system, which includes the equipment, the
batteries, and the wiring to/from and between the
batteries. To locate and correct a problem with
certainty, initial diagnosis and testing must include
all elements of the system. The charger is
constructed so all parts can be tested and replaced
with basic hand tools.
See the appropriate owners manual, the model
number listed on the owners manual should match
the model number on the faceplate of the charger,
for detailed installation, operating procedures and
safety precautions. FOLLOW ALL SAFETY
PRECAUTIONS.
