Battery Load Tester

Instruction Manual

Simplied Check Program for Charging Systems

The SB-3 is a variable load battery tester that provides a simplied check

for the alternator and starter.

CONGRATULATIONS

The automotive electrical system consists of a battery, starter, solenoid

(usually mounted on the starter), ignition switch, alternator with connecting

cables and wires. All parts of the electrical system must be operating

properly for a vehicle to provide dependable transportation. Whenever a

component fails, the whole system should be checked to insure that the

failure was not caused by another part of the system.

The SB-3 model is a simplied approach to test the battery and simplied

check of the system. This insures that you will be making only the

necessary repairs, resulting in satised customers and increased business.

To gain a complete understanding of how this tester works, and to derive

the maximum benets from this unit, we recommend reading through the

entire instruction before testing.
