# Service bulletin 9100338REV1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin

## NHTSA's summary

"GENERATOR Engine Prior to alternator/generator removal: 1. Inspect \& check all electrical connections to the alternator a. 2\-way connector containing field control circuit \& alternator sense voltage circuit. b. Unplug \& plug\-in the 2\-way connector for field \& sense circuit. Verify the connection is tight \& check for any bent pins in alternator connector or damage to female terminals in connector. c. Check Alternator B\+ Stud connection to be sure nut is securing positive cable terminal properly \(i.e. nut is clamping terminal \& connection is tight\). d. Check fuse between the alternator B\+ stud \& PDC terminal to make sure it is not blown. e. Be sure to follow service manual sections on ALTERNATOR CONTROL CIRCUIT DIAGNOSTIC \& ALTERNATOR SENSE CIRCUIT DIAGNOSTIC looking for any opens \& shorts \(to ground or battery voltage\). 2. Check/verify all grounds in the charging system circuit a. Check tightness of mounting bolts securing alternator to engine block. Alternator is a case ground component. b. Check main ground from engine to chassis; connection must be tight. c. Check battery ground cable connections are tight. d. Potentially, loosen alternator mounting bolts, without removing alternator, and re\-tighten to torque specifications in service manual. e. After all steps above are complete, re\-start engine \& check charging system operation. 3. Verify that the Smart Charging System is not the reason for alternator low voltage \& current output \(Amps\). a. Alternator charging can be suspended during engine idle operation because of the Smart Charge strategy. b. Refer to service manual section ""System Operation \- Smart Charging System"". c. Refer to Star Case S2008000031 Rev A for low charging voltage \& Smart Charge Mode Voltage Range diagram \& mode descriptions. d. The alternator has no internal regulator; thus, has no smart circuitry. All alternator control signals come from ECM. 4. If alternator is faulty, remove alternator \& mounting bolts. Return alternator with bolts for analysis at QEC."
