Test E: Charge System Indicator Flickers Or Operates Intermittently
- Turn ignition switch to OFF position. Measure voltage between generator terminal "F" and ground. See Figure
. If battery voltage is present, go to next step. If battery voltage is not present, go to step 3
.
- Start engine. Connect jumper wire between generator terminal "A" and battery positive terminal. See Figure
. Observe charge warning indicator. If indicator flickers, replace voltage regulator. See VOLTAGE REGULATOR
under REMOVAL & INSTALLATION. Retest system operation. If indicator does not flicker, repair Black wire or connections between generator and battery. See WIRING DIAGRAMS
. Retest system operation.
- Remove generator. See GENERATOR
under REMOVAL & INSTALLATION. Inspect brush holder screws (generator terminals "A" and "F"). See Figure
. If screws are okay, go to next step. If screws are loose, clean and tighten screws to 26 INCH lbs. (3 N.m). Retest system operation.
- Remove voltage regulator. See VOLTAGE REGULATOR
under REMOVAL & INSTALLATION. Measure resistance between each generator slip ring and ground. See Fig 1
. If resistance is 200 ohms or greater, replace voltage regulator. If resistance is less than 200 ohms, clean accumulated grease or dirt from around slip rings and recheck resistance. If resistance is still less than 200 ohms, replace generator. See GENERATOR
under REMOVAL & INSTALLATION.
