Test Ch-5, Checking For Intermittent Problems
NOTE:
Perform TEST CH-4, CHARGING SYSTEM VOLTAGE HIGH (CODE 46)
before proceeding.
- Actuate alternator field. Put DRB-II in voltmeter mode. Probe Dark Green wire at back of alternator. Voltage should cycle from zero to battery voltage every 1.4 seconds.
- While watching DRB-II, wiggle wires between alternator and PCM. If any interruption in the voltage cycle, repair wire at point at which cycle was interrupted. If there is no interruption of voltage cycle, test is complete. Perform CHARGING VERIFICATION (CH-VER) test.
