Coil Test - Ignition Coil Application
Peak Amps is the peak current driving
the coil. It is regulated by the module.
A typical Peak Amp reading should be
about from 5 to 10 amps.
Build Time, or ramp time, is the time
it takes the amperage to reach its
maximum.
Drive Time is the time the coil is actively driven.
Analysis of Test Results
If Peak amps is low look for a bad connection between the module
and coil. Long Build Time may be caused by high resistance in
the connection from the ignition module to the coil. Short Build
Time may be caused by a shorted coil. Build Time will be slightly
longer during cranking.
