Test No 2 - Battery Capacity Test
The battery capacity test is per-formed to determine
if the battery is in satisfactory condition. See "Battery"
Section B. If the battery passes this test, continue the
Test No 3 - Voltage Drop Test
Generally, the starting or cranking circuit is a series
circuit from the battery insulated post to the starting
motor solenoid, to the motor, to ground (chassis) and
return to the battery ground post, Fig. 6.
In the cranking circuit we also have a cranking
control circuit, Fig. 6. In this circuit the solenoid is
controlled or operated by closing an ignition switch or
push button starting switch at the instrument panel. In
this cranking control circuit there are frequently some
safety switches such as transmission "neutral safety
switch" and/or vacuum-operated cutout switch.
