TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 i. Time delay TD2 (87, figure 5-1). (1) Tests for Replacement Components. Check the following components on TD 2, figure 5- 14. (a) Check transistor Q1 by connecting to transistor tester and testing for current gain or 100 min, leakage, or short. (b) Check capacitors C1 and C2 by connecting each to a capacitor tester and checking for leakage and capacitance. C1 must read 10 microfarads, 25 volts, ±5 percent. C2 must read 47 microfarads, 50 volts, ±10 percent. (c) Check resistors, using an ohmmeter, for the following resistances. R4 820 ohms, 25 watts, ±5 percent R1 2 k megohms, 1 watt, ±5 percent R2 2.7 megohms, 25 watts, ±5 percent R3 390 k, 0.25 watt, ±5 percent WARNING BEFORE STARTING ANY MAINTENANCE PROCEDURE, SET MAINTENANCE LOCKOUT SWITCH TO LOCKOUT. DISCONNECT NEGATIVE CABLE FROM BATTERIES. REMOVE EXTERNAL POWER BY OPENING CB101 (EXTERNAL POWER CIRCUIT BREAKER) AND DISCONNECTING POWER CABLE FROM RECEPTACLE J101 (120V RECEPTACLE). (2) Test of TD2. (a) Connect time delay circuit as shown in figure 5-14. (b) Close switch S1. Time the period it takes before lamp DS1 lights. It must be 3.5 to 4.5 seconds or TD is defective. (3) Repair. If any of the replaceable components tested in 1 (above) are defective, TD2 is repairable by replacing the defective component. If the printed circuit wiring or a terminal Figure 5-11.
