Getting the Jaguar to Run – Installing the Battery

The past couple of days I have been working to trackdown the starting problems with the 1987 Jaguar XJ6. So the following description should help if you have similar problems.

The first thing I did was to install the battery. This process applies to all top mount batteries.

Cautions:

  • When you work with standard lead-acid (sulfuric acid) batteries protect your eyes. Wear goggles to protect against acid splashing in the eyes.
  • Protect your hands with heavy waterproof gloves.
  • Wear older clothes if you have concern about acid eating through good clothes.
  • Make sure you can handle the battery safely. Batteries are heavy and could hurt you or the car if you slip and drop the battery.
  • Make sure the battery can go into the correct location without the battery terminals touching bare metal and shorting out the battery.

  • Lead is a heavy metal poison.
  • Do not eat or smoke while working with lead. Wash your hands before eating or smoking after working with lead.
  • Put a container (shallow large catchpan)on the ground or floor under the battery area to catch lead dust, acid spills, and rinse water.

1. If you don’t have a terminal cleaner, buy one. OLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERAClean the terminals before installing the battery.

2. Use the brush part to clean inside the clamps. OLYMPUS DIGITAL CAMERAClean tobright metal. If the clamps are really corroded, you will also want to rinse them off with a baking soda and water mix (or some commercial mix made for the purpose). Flush the soda water mix with plain water. Dispose of the rinse water at a hazardous waste location.

3. Use the hollow part to clean the battery posts. OLYMPUS DIGITAL CAMERAAgain, clean to bright metal.

Note: Always install the positive cable first. And always take off the positive cable last. This reduces the chance to have some rather large sparks if your wrench makes contact with some metal in the car.

Additional process: Some people like to puta bit of anti-corrosion compound or petroleum jelly on the inside of the clamps. Another thing some people favor are the anti-corrosion pads that can be put on the terminal posts under the clamps.

4. Install the positive cable (normally the cable will have a red plastic covering).OLYMPUS DIGITAL CAMERA Use an adjustable wrench, or similar tool, to hold the square end of the clamp bolt. On a lot of cars,the nut will take a 1/2 inch (13 mm) socket. Tighten the nut.

Technical Information: If you are a real techfreak and own the tools, get out your 1/4 inch drive torque wrench.Tighten the nut to 50 to 70 in lbs. That information comes from the Trojan Battery Company web site.

5. Install the negative cable (normally the cable will have a black plastic covering). OLYMPUS DIGITAL CAMERATighten the clamp on the negative terminal of the battery the same way you tightened the clamp on the positive terminal.

6. Install any hold down clamps or hardware.

7. The battery is installed. You are ready to check the next location on the Jaguar that can cause problems.
