BATTERY booster battery and the other end of same cable to positive (+) terminal of discharged battery (Figure 9). On positive ground vehicles, connect jumper cables between negative (-) battery terminals. Figure 9 - Proper Jumper Cable Connections (Negative Ground Vehicles Shown) 5. On negative ground vehicles, attach one end of the remaining jumper cable to the negative terminal of the booster battery and the other end to a ground at least 304 mm (12 inches) from the battery of the vehicle being started (Figure 9).  (DO NOT connect directly to the negative post of the dead battery.) The ground connection must provide good elec-trical conductivity and current carrying capacity. On the positive ground vehicles, connect jumper cable between positive (+) terminal of booster battery and ground on the stalled vehicle. CAUTION - TAKE CARE TO BE SURE THE CLAMPS FROM ONE CABLE DO NOT INADVERTENTLY TOUCH THE CLAMPS ON THE OTHER CABLE. DO NOT LEAN OVER THE BATTERY WHEN MAK-ING CONNECTIONS. AVOID MOVING, HOT OR ELECTRICAL HAZARDS SUCH AS FANS, MANIFOLDS AND SPARK PLUG TERMINALS WHEN CONNECTING CABLES. 6. Be sure everyone is standing away from vehicles. Start the engine of the vehicle with the booster battery.  Wait a few minutes, then attempt to start the engine of the vehicle with the discharged battery. 7. Do not operate the starter for more than 15 seconds. Wait at least 15 seconds between starting attempts to allow starter motor to cool.  If the engine does not start after several cranking attempts, check to be sure that the clamps are secure.  If the engine still continues to not start, refer to the appropriate service manual for troubleshooting procedures. 8. After starting, allow the engine to return to idle speed.  Remove ground cable connection from the vehicle with discharged battery.  Then remove the other end of the same cable from the booster battery. 9. Remove the other cable by disconnecting from the discharged battery first and then disconnect the opposite end from the booster battery. 10.  Remove and discard cloths covering battery vents. TESTING A battery test should be performed whenever battery trouble is suspected. Battery testing will determine if: 1. Battery is satisfactory and can remain in service. 2. Battery should be recharged before placing it back in service. 3. Battery must be replaced. A complete battery test, as outlined below, will include these steps: 1. Visual Inspection 2. State of Charge Test 3. Battery Capacity (Load) Test CAUTION - WHEN PERFORMING BATTERY TEST, OBSERVE RULES OF SAFETY.  REFER TO PRECAUTIONS. ALWAYS FOLLOW INSTRUCTIONS OF TEST EQUIPMENT MANUFACTURER. STEP 1.  VISUAL INSPECTION a. Visually Inspect the outside of the battery for obvious damage such as cracked or broken case or cover which would allow electrolyte loss. Check for terminal damage.  If obvious physical damage Is found, replace the battery.  If possible, determine the cause of damage and correct. b. Check electrolyte level. On maintenance free type batteries, access to battery cells can be obtained as follows: Side Terminal Batteries: Use a knife blade to cut through top plaque cen- ter section.  (Cut on dotted lines.)
