TM 5-6115-584-12 NAVFAC P-8-622-12 TO-35C2-3-456-1 NOTE Always detach negative (–) cable first and reattach it last. b. Battery Top (Hold–down) Frame (see figure 3-23). (1) Remove. Tag and disconnect battery ca- bles (10) and jumper cable (11 ) from batteries (1). Remove six nuts (4) and flatwashers (5) holding top frame (2) in place, and remove top frame. If hook bolts (3) do not need replacing, they need not be removed from frame (6). (2) Replace. Hook six bolts (3) onto bottom frame (6). Place top frame (2) over batteries (1) mak- ing certain hook bolts slide through the top frame. Secure top frame in place with six flatwashers (5) and nuts (4). Reattach battery cables (10) and jumper ca- ble (11). (3) Repair. Straighten battery top frames making certain they fit securely over batteries and hold batteries in place. c. Storage Batteries. Battery electrolyte can cause severe burns to the skin. Always flush ex- posed parts of the skin with water as quickly as possible. (1) Test. Charge battery for a sufficient time for battery to be fully charged (1 to 2 hours). Test each cell of battery separately using a hydrometer. Remove cap from one cell and draw fluid from that cell into hy- drometer. Hydrometer must register a specific gravity of 1.260 to 1.280. If specific gravity is below 1.260, charge battery. See figure 4–17. Replace fIuid into cell and replace cap. Check each battery cell using this procedure. If one or more cells in a battery will not take a charge, replace battery. (2) Remove. Remove battery cables and top frames, a and b above. Remove batteries from battery frame. (3) Replace. Place batteries in battery frame with negative (-) terminals toward control panel end of generator and positive (+) terminals toward blower housing end of generator. Install battery top frame and battery cables as outlined above. Figure 4–17. Testing Batteries 4-26. ENGINE STARTER ASSEMBLY, a. Test. On equipment (see figure 4–1 9). On ASK equipped generators, remove BATTERIES ac- cess door. (1) Make sure batteries are fully charged and that all battery and starter cables are serviceable and properly installed. Disconnect all starter to solenoid connection. (2) Connect voltmeter as shown in figure 4–19, Test a. If voltage is indicated, solenoid is defec- tive. Proceed to step (4). (3) Reconnect all starter to solenoid connec- tions. Connect voltmeter as shown in figure 4–19, Test a. If battery voltage (24 volts) is not indicated, the starter (B1 ) may be defective. Proceed to step (4). (4) Momentarily connect a jumper as shown in figure 4–19, Test b. Voltmeter reading should drop to zero and starter should crank engine. If voltmeter reading does not drop to zero, solenoid is defective. If voltmeter readings drop to zero but starter fails to crank engine, starter is defective. b. Removal (see figure 4-18). On ASK genera- tors remove batteries access door. Tag and disconnect leads (1) thru (6). On Style I Starters, re- move nut (7), Iockwasher (8), screw (9). Loosen but do not remove screw (1 0), Iockwasher (11) and swing 4-26 Change 10
