Delco-Remy Regulator Adjustment
(1) Potentiometer adjustment screw. (2) Transistor pins.2. Remove the rubber from the potentiometer so that the small screw can be seen.3. Connect a voltmeter across the batteries to measure the regulation of the voltage. The batteries must have a good charge for this measurement.4. Operate the alternator at medium speed for 30 seconds and take a measurement of the voltage. The voltage must be 27.5 1.0 volts. Turn the small screw counterclockwise to get less voltage output and clockwise to get more voltage output.5. After adjustment has been made, put a thin layer of 3S6252 Silicone Rubber Sealant on the adjustment screw and install the covers. Make sure the location of the wires to the voltage regulator is not over the transistor pins. The transistor pins could make holes in the insulation for the wires and cause a short circuit.7N9720 Alternator 24V 35A (Bosch Number 0-122-469-001); 9G9538 Alternator 24V 50A (Bosch Number 0-122-469-002)
7N9720 AlternatorThe solid state regulator used with the Bosch Alternator is totally enclosed and non-adjustable. If the rate of charge is not correct a replacement of the regulator is necessary.9G4574 24V 35A (Nippondenso Number 100211-0860); 6T7223 24V 50A (Nippondenso Number 100211-0890)
9G4574 AlternatorNo adjustment can be made to change the rate of charge on the alternator regulator. If rate of charge is not correct, a replacement of the regulator is necessary.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 starter solenoid. Starter solenoid operation can be heard as the pinion of the starter motor is engaged with the ring gear on the engine flywheel.If the solenoid for the starter 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
