Test Ch-5, Checking For Intermittent Problems

NOTE: Perform TEST CH-4, CHARGING SYSTEM VOLTAGE HIGH before proceeding.

Actuate alternator field. Put DRB-II in voltmeter mode. Probe Dark Green wire at back of alternator.
NOTE: Voltage should cycle from zero to battery voltage every 1.4 seconds.
While watching DRB-II, wiggle wires between alternator and SBEC. If there is any interruption in voltage cycle, repair wire at interruption point in cycle. If there is no interruption of voltage cycle, test is complete. Perform TEST CH-VER, CHARGING VERIFICATION .
