PART THREE
MAINTENANCE INSTRUCTIONS
Section V. PREVENTIVE MAINTENANCE TECHNIQUES
14. Meaning of Preventive Maintenance
Preventive maintenance is a systematic series of operations performed at regular intervals on equipment, when turned off, to eliminate major break-downs and unwanted interruptions in service, and to keep the equipment operating at top efficiency. To understand what is meant by preventive maintenance, it is necessary to distinguish between preventive maintenance, trouble shooting, and repair. The prime function of preventive maintenance is to prevent break-downs and, therefore, the need for repair. The prime function of trouble shooting and repair is to locate and correct existing defects. The importance of preventive maintenance cannot be overemphasized. The entire system of communications depends upon the readiness and operating efficiency of each item of equipment when it is needed. In a similar manner, the test equipment by which this condition of readiness in communications equipment is realized must be kept in excellent operating condition at all times.
15. Description of Preventive Maintenance Techniques
a. General. Most of the electrical parts used in Battery Tester TS-183/U require routine preventive maintenance. Those requiring maintenance differ in the amount and kind required. Because hit-or-miss maintenance techniques are not reliable, definite and specific instructions are needed. This section of the manual contains these specific instructions and serves as a guide for personnel assigned to perform the six basic maintenance operations, namely: Feel, Inspect, Tighten, Clean, Adjust, and Lubricate. Throughout this manual the lettering system for the six operations will be as follows:
F—Feel. C—Clean.
I—Inspect. A—Adjust.
T—Tighten. L—Lubricate.*
♦Lubrication of Battery Tester TS-183/U is not required.
9
The first two operations establish the need for the other four. The selection of operations is based on a general knowledge of field needs. For example, the dust encountered on dirt roads during cross-country travel filters into the equipment no matter how much care is taken to prevent it. Rapid changes in weather (such as heavy rain followed by blistering heat), excessive dampness, snow, and ice tend to cause corrosion of exposed surfaces and parts. Without frequent inspections and the necessary performance of tightening, and cleaning operations, equipment becomes undependable and subject to break-down when it is most needed.
b. Feel. The feel operation is used to check the tightness of the jack contact springs and for leakage of oil from the load resistor cases.
c. Inspect. Inspection is the most important operation in the preventive maintenance program. A careless observer will overlook the evidences of minor trouble. Although these defects may not interfere with the performance of the equipment, valuable time and effort can be saved if they are corrected before they lead to major break-downs. Make every effort to become thoroughly familiar with the indications of normal functioning, in order to be able to recognize the signs of a defective set. Inspection consists of carefully observing all parts of the equipment, noticing their color, placement, state of cleanliness, etc. Inspect for the following conditions:
(1) Placement, by observing that all leads and cabling are in their original positions.
(2) Cleanliness, by carefully examining all recesses in the units for accumulation of dust, especially between connecting terminals. Parts, connections, and joints should be free of dust, corrosion, and other foreign matter. In tropical and high-humidity locations, look for fungus growth and mildew.
(3) Tightness, by testing any connection or mounting which appears to be loose.
d. Tighten, Clean, and Adjust. These operations are self-explanatory. Specific procedures to be followed in performing them are given wherever necessary throughout part three.
Caution: Do not tighten screws, bolts, and nuts carelessly. Fittings tightened beyond the pressure for which they are designed will be damaged or broken.
16. Common Materials Needed
The following materials will be needed in performing preventive maintenance:
Clean cloth.
#0000 sandpaper.
Crocus cloth.
Solvent, Dry Cleaning.
10
Carbon tetrachloride, technical grade.
Polish, metal, paste.
Note. Gasoline will not be used as a cleaning fluid for any purpose. Solvent, Dry Cleaning, is available as a cleaning fluid through established supply channels. Oil, Fuel, Diesel, may be used for cleaning purposes when dry-cleaning solvent (SD) is not on hand. Carbon tetrachloride will be used as a cleaning fluid only in the following cases: where inflammable solvents cannot be used because of the fire hazard, and for cleaning electrical contacts including relay contacts, plugs, commutators, etc.
1 7. Voltmeter (fig. 6)
a. Inspect (I). Inspect the meter case for cracks at soldered joints. Check the hermetically sealed bushings for cracked or broken insulation. Check the soldered connections to the meter. Inspect the meter bellows for fractures.
b. Tighten (T). Tighten the four screws which secure the meter to the operating panel.
c. Clean (C). Clean the meter case and the glass cover with a clean, dry cloth or a cloth moistened with dry-cleaning solvent (SD) if dirt is difficult to remove.
d. Adjust (A). The meter must be zero-adjusted if the pointer does not return exactly to zero when the battery tester is not in operation. View the pointer from the front and tap lightly with the fingers to overcome any slight bearing friction before deciding that adjustment is necessary. If adjustment is necessary, slowly turn the ZERO ADJUST screw, located below the meter, until the pointer is at zero.
1 8. Load Resistor and Multiplier Resistor Cases
a. Feel (F). Feel the surfaces of the load resistor cases for leaking oil.
b. Inspect (I). Inspect the resistor cases for cracks at the soldered joints. Examine all soldered connections on the terminals of the resistor cases.
c. Tighten (T). Tighten all screws which secure the resistor cases to the operating panel.
d. Clean (C). Clean the hermetical-seal bushings with a clean cloth moistened with dry-cleaning solvent (SD).
19. Jacks
a. Feel (F). Insert Plug PL-68 in each of the 32 jacks. Observe by feeling, which jacks loosely hold the plug.
b. Inspect (I). Inspect the jacks for loose mounting nuts. Check the wiring to each of the jacks for broken or shorted connections. Inspect the contact surfaces of the jacks for dirt and corrosion.
11
12
c. Tighten (T). Tighten all loose jack mounting nuts.
d. Clean (C). Clean the contact surfaces on the jack contact springs with crocus cloth or #0000 sandpaper. Wipe springs and dirty insulation with a clean cloth moistened with carbon tetrachloride, technical grade.
e. Adjust (A). Adjust the jack contact springs which do not exert sufficient pressure, to tightly hold the plug when it is inserted.
20. Plug and Test Prods
a. Inspect (I). Inspect the plugs and test prods for broken or cracked cases and dirt or corrosion on the contact surfaces. Inspect the leads to which the plug and test prods are connected for broken or frayed insulation. Loosen and slide back the insulating sleeves to expose the soldered joints. Inspect the joints for solid connections.
b. Clean (C). Clean all dirt or corrosion from the contact surfaces of the plug and test prods.
Warning: Jacks JK-33-A and Plug PL-68 must be visually inspected at least once each week and cleaned with Polish, Metal, Paste, Signal Corps stock No. 6G1516, when necessary. Failure to comply with this operation will result in erroneous voltage measurements due to excessive jack and plug contact-resistance.
21. Preventive Maintenance Check List
The following check list is a summary of the preventive maintenance to be performed on Battery Tester TS-183/U. The suggested time intervals shown on the check list may be reduced at any time by the local commander. However, for the best performance of the equipment, perform operations at least as frequently as called for in the check list. Extremely hot, cold, or dusty locations may necessitate more frequent scheduling of maintenance operations. Operations are indicated by the letters of the word FITCAL. For example, if the letters ITC are in the operations column, the item to be treated must be inspected (I), tightened (T), and cleaned (C).

Section VIII. THEORY OF EQUIPMENT
22. General (fig. 7)
a. Voltmeter Circuit. The voltmeter circuit used in Battery Tester TS-183/U is entirely conventional and contains a 0-1-milli-ampere D’Arsonval-type meter, which is used in conjunction with a set of series-connected multiplier resistors. The meter resistance is 100 ohms and the sensitivity of the arrangement is 1,000 ohms per volt.
b. Circuit Switching. Circuit switching between voltmeter ranges and load resistors in the battery tester is accomplished by the insertion of Plug PL-68, which terminates one test cord, into any one of the 32 Jacks JK-33-A. The cord attached to the positive prod connects to both the tip and ring of the plug. The insertion of the plug into a jack connects the positive terminal of a battery first to one side of a load resistor, and then to one of the junctions between the series connected multipliers. The other side of the load resistor is connected to a line common with one side of all load resistors. The common line connects through the NO LOAD-TEST LOAD toggle switch to the negative test cord, thereby completing the load resistor circuit'.
Section IX. TROUBLE-SHOOTING PROCEDURES
23. Step-by-Step Procedure
a. Common Faults. Faulty operation of Battery Tester TS-183/U may be experienced through either the failure of the voltmeter or of the load resistors to operate with the plug inserted into one or more of the 32 jacks. Faulty operation of the load resistors is not so easily apparent as faulty operation of the voltmeter. In normal operation of the set, this defect will be noticed by an unchanged
