Test data Ex:
0000001801 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust using screw (A) so that the timer stroke is the value determined using the graph (W) and the formula. [(U), (W)]
2. Adjustment of the position of the intermediate lever.
Insert a shim L1 between the control lever (I) and the idle set screw (G).
Align the intermediate lever (F) with the aligning line (J) and fix intermediate lever's adjusting screw (E) so that it contacts the control lever. [(U), (V)]
3. Adjustment of the FICD
Insert a shim between the control lever (I) and the idle set screw (G). Then, fix the CSD lever (C) in the position where it operates the intermediate lever (F) via the rod (D) using the adjusting screw (B). [(U), (V), (W)]

Information:
6V7070 Heavy-Duty Digital MultimeterThe 6V7070 Heavy-Duty Digital Multimeter is a completely portable, hand held instrument with a digital display. This multimeter is built with extra protection against damage in field applications, and is equipped with seven functions and 29 ranges. The 6V7070 Multimeter has an instant ohms indicator that permits continuity checking for fast circuit inspection. It also can be used for troubleshooting small value capacitors.The 6V7800 Regular-Duty Digital Multimeter (a low cost option to the Heavy-Duty Multimeter) is also available; however, the 6V7800 Multimeter does not have the 10A range or the instant ohms feature of the 6V7070 Multimeter. Make reference to Special Instruction, Form No. SEHS7734 for complete information for use of the 6V7070 and 6V7800 Multimeters.Battery
Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operated. A spark can cause an explosion from the flammable vapor mixture of hydrogen and oxygen that is released from the electrolyte through the battery outlets. Injury to personnel can be the result.
The battery circuit is an electrical load on the charging unit. The load is variable because of the condition of the charge in the battery. Damage to the charging unit will result if the connections (either positive or negative) between the battery and charging unit are broken while the charging unit is in operation. This is because the battery load is lost and there is an increase in charging voltage. High voltage will damage, not only the charging unit, but also the regulator and other electrical components.Use the 4C4911 Battery Load Tester to load test a battery that does not hold a charge when in use. Refer to Operating Manual, Form No. SEHS9249 for more detailed instructions on use of the 4C4911 Battery Load Tester. See Special Instruction, Form No. SEHS7633, Battery Test Procedure, for the correct procedure and specifications to use when testing batteries.Charging System
The condition of charge in the battery at each regular inspection will show if the charging system operates correctly. An adjustment is necessary when the battery is constantly in a low condition of charge or a large amount of water is needed (more than one ounce of water per cell per week or per every 100 service hours).When it is possible, make a test of the charging unit and voltage regulator on the engine, and use wiring and components that are a permanent part of the system. Off-engine (bench) testing will give a test of the charging unit and voltage regulator operation. This testing will give an indication of needed repair. After repairs are made, again make a test to give proof that the units are repaired to their original condition of operation.To check for correct output of the alternator, see the Specifications module.For complete service information, refer to Service Manual Module, Form No. SENR3862. This module is part of REG00636 Service Manual.Before the start of on-engine testing, the charging system and battery must be checked as shown in the Steps that follow:1. Battery must
