TROUBLE DIAGNOSIS WITH BATTERY/STARTING/CHARGING SYSTEM TESTER
Note. To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done as a set from start to finish.
For trouble diagnosis using (J-44373) Model 620 Battery/Starting/Charging System Tester (Scheme 1)- (Scheme 2). After performing trouble diagnosis using battery/starting/charging system tester, use the diagnostic result item chart to perform appropriate test and/or repair. See DIAGNOSTIC RESULT ITEM CHART table.
| Diagnostic Item | Perform Test |
|---|---|
| Charging System Normal | Charging System Is Normal & Will Also Show Diode Ripple Test Result |
| No Charging Voltage | NO CHARGING VOLTAGE OR DIODE RIPPLE NOT DETECTED |
| Low Charging Voltage | LOW CHARGING VOLTAGE |
| High Charging Voltage | HIGH CHARGE VOLTAGE |
| Diode Ripple Normal | Diode Ripple Is Okay & Will Also Show Charging Voltage Test Result |
| Excess Ripple Detected | Replace The Alternator, Perform Diode Ripple Test Again Using Battery/Starting/Charging System Tester To Confirm Repair |
| Diode Ripple Not Detected | NO CHARGING VOLTAGE OR DIODE RIPPLE NOT DETECTED |
