REMOVAL & INSTALLATION



See Figures 1, 2, 3, 4, 5 and 6

For this job you should use gloves and old clothes. Battery acid has a nasty habit of dripping on clothes. Sometimes this goes completely unnoticed, until later, when you discover a hole (or holes) mysteriously eaten through your favorite pair of slacks.

WARNING

Always disconnect the negative (ground) cable first, and, when re-connecting, connect it last to avoid sparks. If the battery sparks or kicks back an electrical surge through the system, expensive components could be damaged or destroyed.

  1. Remove the battery hold-down clamp.

Fig. Fig. 4: With the special wire brush, Clean and expose a shiny surface on the inside of the batter terminal (cable clamp)

  1. Clean the cable clamps, using a wire brush, both inside and out.
  2.  
  3. Install the battery and hold-down clamp or strap. Connect the positive, and then the negative cable (see Warning above). Do not hammer post cables onto the terminal posts. The complete terminals should be given a light external coating of petroleum jelly or grease to help prevent corrosion. There are felt washers available which have been impregnated with an anti-corrosion substance. These can be slipped over the battery posts before installing the cables, and are available in most auto parts stores.
