Make certain that field wire (5) is not located over transistor pins (6). The pins can make a hole in the insulation of the wire.
7N9720 Alternator 24V 35A
7N9720 AlternatorNo adjustment can be made to change the rate of charge on the alternator regulators. If rate of charge is not correct, a replacement of the regulator is necessary.9G4574 Alternator 24V 35A
9G4574 AlternatorNo adjustment can be made to change the rate of charge on the alternator regulators. If rate of charge is not correct, a replacement of the regulator is necessary.9L5938 Alternator; Pulley Nut Tightening

Tools To Tighten Alternator Pulley Nut
(1) 8T9293 Torque Wrench. (2) 8S1588 Adapter (1/2 inch female to 3/8 inch male). (3) 2P8267 Socket Assembly. (4) 8H8517 Combination Wrench (11/8 inch). (5) 8T5314 Socket.Starting System
Use the multimeter in the DCV range to find starting system components which do not function.Move the start control switch to activate the starting motor solenoid. Starting motor solenoid operation can be heard as the pinion of the starting motor is engaged with the ring gear on the engine flywheel.If the solenoid for the starting motor will not operate, it is possible that the current from the battery did not get to the solenoid. Fasten one lead of the multimeter to the connection (terminal) for the battery cable on the solenoid. Put the other lead to a good ground. A zero reading is an indication that there is a broken circuit from the battery. More testing is necessary when there is a voltage reading on the multimeter.The solenoid operation also closes the electric circuit to the motor. Connect one lead of the multimeter to the solenoid connection (terminal) that is fastened to the motor. Put the other lead to a good ground. Activate the starting motor solenoid and look at the multimeter. A reading of battery voltage shows the problem is in the motor. The motor must be removed for further testing. A zero reading on the multimeter shows that the solenoid contacts do not close. This is an indication of the need for repair to the solenoid or an adjustment to be made to the starting motor pinion clearance.Make a test with one multimeter lead fastened to the connection (terminal) for the small wire at the solenoid, and the other lead to the ground. Look at the multimeter and activate the starting motor solenoid. A voltage reading shows that the problem is in the solenoid. A zero reading is an indication the the problem is in
