With between 600 and 700 different types of starting, lighting, ignition
and battery equipment used in over 1,300 makes and models of cars, no

discharge, motor and generator, test data, etc. The AMBU System supplies
these bewildering details, quickly, easily and accurately. No matter
what is wrong—The AMBU System shoots the trouble and never fails.
