Batteries, Starting and Charging Systems
Battery Testing
Conventional load testing
Resistive test (will identify batteries that may fail within a
month)
Check battery connections
Starter Testing
Check starter voltage and amperage draw
Alternator Testing
Check output (idle & 2000 RPM)
Check diodes and pattern
Check voltage ripple (idle & 2000 RPM)
Additional Testing
Draw Testing
Check for a parasitic draw that may drain a battery due to lights or
a module staying on
