TM 5-3820-236-24-4 BATTERY Connect  the  positive  (+)  charger  lead  to  positive  battery terminal and negative (-) lead to negative terminal.  If the battery is in the vehicle, connect the negative lead to the engine   block   if    the    vehicle    has    a    "negative    ground" (negative    battery    terminals    is    connected    to    ground). Connect   the   positive   lead   to   ground   if   vehicle   has   a "positive   ground."   "Rock"   the   charger   lead   clamps   to make certain a good connection has been made. Turn  the  charger  "ON"  and  slowly  increase  the  charging rate until recommended ampere value is reached. CAUTION   -   IF   SMOKE   OR   DENSE   VAPOR   COMES FROM THE BATTERY, SHUT OFF THE CHARGER AND REJECT  THE  BATTERY.    IF  VIOLENT   GASSING   OR SPEWING  OF  ELECTROLYTE  OCCURS,  REDUCE  OR TEMPORARILY HALT THE CHARGING. If    the    engine    does    not    crank    satisfactorily    when    a recharged   battery   is   installed,   load   test   the   battery   as outlined under TESTING.  If the battery passes the "Load Test",  the  vehicle’s  fuel,  ignition,  cranking  and  charging systems   should   be   checked   to   locate   and   correct   the problem.    If  it  does  not  pass  the  load  test,  the  battery should be replaced. When   an   engine   does   not   crank   satisfactorily   with   a battery    which    was    not    recharged    before    installation, recharge the battery and subject it to the load test.  If the battery   fails,   replace   it;   if   it   tests   satisfactorily   and   the engine still does not crank satisfactorily check the vehicle systems    mentioned    above    to    locate    and    correct    the problem. REMOVAL AND INSTALLATION REMOVAL 1. Make     sure     all     electrical     loads     (lights,     ignition, accessories) are turned "OFF". 2. Remove battery cover (where used). 3. Note    locations    of    battery    positive    and    negative terminals in relation to surrounding vehicle components.    Battery  must  be  installed  in  the  same position. 4. Loosen    battery    hold-down    hardware    and    remove battery from carrier tray. 5. Inspect    battery    cables    and    replace    if    necessary. Clean cable connector terminals with a wire  brush. Clean  and  tighten  battery  cable  ground,  starter  relay and starter connections. 6. Inspect battery hold-down hardware and battery tray. Replace worn or damaged parts.    Remove  corrosion with a wire brush and/or wash with a weak solution of baking soda and water.  Rinse and dry.  Repaint parts if needed to prevent rusting. Make  sure  no  foreign  objects  such  as  stones,  bolts, nuts,   etc.      which   could   damage   battery   are   left   in battery tray. INSTALLATION When replacing the battery, make sure that battery to be installed   has   sufficient   capacity   to   cover   the   electrical requirements  of  the  vehicle.    Use  of  an  under-capacity battery   will   result   in   poor   performance   and   premature battery   failure.      The   original   equipment   battery   can   be used as a minimal guide, but is often misleading since the vehicle   owner   may   have   installed   additional   electrical accessories on the vehicle. Be  sure  battery  is  at  full  charge  when  installed.    If  the battery   has   been   in   storage   for   some   time   or   if   the installation  is  being  made  in  sub-freezing  temperatures, the  battery  should  be  given  a  boost  charge  before  being installed. 1. Place battery in battery tray with terminals in proper position.  Battery should rest level in tray. 2. Install  battery  hold  down  hardware  and  tighten  until battery is firm and secure. CAUTION - DO NOT OVERTIGHTEN BATTERY HOLD- DOWNS.  OVERTIGHTENING COULD DAMAGE BATTERY RESULTING IN EARLY FAILURE. 3. Apply  light  coat  of  terminal  grease  (IH  part  number 472141-C1)  to  battery  and  cable  terminals  to  inhibit corrosion. 4. Connect  battery  cables  to  battery.    Check  for  proper battery polarity with respect to the vehicle. "Reversed" polarity may cause serious damage to the electrical system.  Connect ground cable last. Tighten terminal fasteners as follows:  DO NOT OVERTIGHTEN. Side Terminals: 7-10 Nm (60-90 lb.  in.  or 5-7 lb.  ft.) Top Terminals: 13-20 Nm (10-15 lb.  ft.) Taper Post Terminals: 5.5-8 Nm (50-60 lb.  in.  or 4-6 lb.  ft.) NOTE  -  New  batteries  must  be  coded  to  Indicate  month and year of installation. 5. Start     engine     and     check     operation     of     vehicle’s charging    system.        If    necessary,    adjust    or    repair charging system to obtain correct charging output. 6. Install battery cover (where used). CTS-4111B - Page 15
