Unit Troubleshooting (Con't).MALFUNCTIONTEST OR INSPECTIONCORRECTIVE ACTIONStep 4.With engine running, test stator assembly (alternator) output by disconnecting engine wiringharness connector from regulator (see paragraph 4-129). Using a multimeter set to DC voltage,measure stator assembly output.If stator assembly output is within 12 V dc ± 1 V dc, replace damaged regulator (seeparagraph 4-129).20. BATTERY OVERCHARGES.l Remove all jewelry such as I.D. tags, rings, bracelets, etc. If jewelry contacts batteryterminal, a direct short will result causing instant heating of jewelry which will resultin serious injury or death to personnel.l Battery acid (electrolyte) is extremely dangerous.

Battery gases may explode, causing serous injury or death topersonnel.NOTERefer to engine wiring diagram for assistance (see paragraph 4-135).With engine running, test stator assembly (alternator) output by disconnecting engine wiring harness connec-tor from regulator (see paragraph 4-129). Using a multimeter set to DC voltage, measure stator assemblyoutput.If stator assembly output is within 12 V dc ± 1 V dc, replace damaged regulator (seeparagraph 4-129).If stator assembly output is not 12 V dc ± 1 V dc, replace damaged stator assembly (seeparagraph 4-116).4-42
