The black cover has been removed to show alternator rectifier/regulator assembly. The alternator contains field coil diodes (low current) (Item 1) [Figure 60-31-2], grounded heat…

Stop the engine. Raise the operator cab. (See Raising The Operator Cab on Page 10-30-1.) Loosen the alternator mounting bolt (Item 1) [Figure 60-31-1]. Loosen…

Reverse the order of disassembly. Do not assemble the rear case half. Place the rotor in soft jaws when tightening the shaft nut. Tighten to…

NOTE: In the diode tests there should be continuity in one direction only. If the diode being tested shows no continuity or continuity in both…

Touch one probe to one of the slip rings and the other probe to the rotor shaft [Figure 60-30-11]. There should be no continuity. Replace…

Touch the probes to the slip rings [Figure 60-30-10]. The ohmmeter should read between 3.065-33.85 ohms. If there is no continuity replace the rotor.  

Touch one probe to a bare stator lead and the other probe to the bare metal surface of the stator [Figure 60-30-9]. There should be…

Use an ohmmeter to test the stator. Touch the probes to two of the bare stator wires [Figure 60-30-8]. Move one of the probes to…

Disassemble the alternator. [Figure 60-30-7]. Remove the regulator cover and regulator. Remove the four bolts holding halves together. Pry the halves apart (use a press…
