See figure 4–16. Attach positive cable(+) to positive terminal on one battery and negative ca-ble (–) to negative terminal on the other battery.Tighten all terminal connectors securely.N O TEAlways detach negative (–) cable firstand reattach it last.b. Battery Top (Hold–down) Frame (see figure3 - 2 ).(1) Remove. Tag and disconnect battery ca-bles (1 and 3) and jumper cable (4) from batteries (6).Remove six nuts (7) and flatwashers (8) holding topframe (5) in place, and remove top frame. If hook bolts(9) do not need replacing, they need not be removed.(2) Replace. Hook six bolts (9) onto bottomframe (6). Place top frame (5) over batteries (6) mak-ing certain hook bolts slide through the top frame.Secure top frame in place with six flatwashers (8) andnuts (7). Reattach battery cables (1 and 3) and jumpercable (4).(3) Repair. Straighten battery top framesmaking certain they fit securely over batteries and holdbatteries in place.c. Storage Batteries.Battery electrolyte can cause severeburns to the skin. Always flush ex-posed parts of the skin with water asquickly as possible.The 6TN and 6TL batteries can be mixed or matched.However, maintenance–free batteries cannot bemixed or matched with military batteries. The 6TN andor the 6TL batteries will perform properly in hot weatheras long as electrolyte levels are carefully monitored. Ifthe electrolyte expands and causes the level to rise,some fluid must be removed. If the level becomes toolow due to evaporation, distilled water maybe used toobtain the proper level. A good grade of drinking water(excluding mineral waters) may be used if distilledwater is not available.Electrolyte(NSNs6810–00–249–9354and6810–00-843-1640) have a specific gravity of 1.280and should be used in these batteries to a lower spe-cific gravity.(1) Test. Charge battery for a sufficient timefor battery to be fully charged (1 to 2 hours). Test eachcell of battery separately using a hydrometer. Removecap from one cell and draw fluid from that cell into hy-drometer. Hydrometer must register a specific gravityof 1.260 to 1.280. If specific gravity is below 1.260,charge battery. See figure 4–17. Replace fluid into celland replace cap. Check each battery cell using thisprocedure. If one or more cells in a battery will not takea charge, replace battery.(2) Remove. Remove battery cables and topframes, a and b above. Remove batteries from batteryframe.(3) Replace. Place batteries in battery framewith negative (–) terminals toward control panel end ofgenerator and positive (+) terminals toward blowerhousing end of generator. Install battery top frame andbattery cables as outlined above.Figure 4–17. Testing Batteries4–26. ENGINE STARTER ASSEMBLY.a. Test. On equipment (see figure 4–19). OnASK equipped generators, remove batteries accessdoor.(1) Make sure batteries are fully charged andthat all battery and starter cables are serviceable andproperly installed.(2) Connect voltmeter as shown in figure4–19, Test a. If voltage is indicated, solenoid maybedefective. Proceed to step (4).4-26Change 11
