How to jump start it - 1990 Buick Riviera

Make sure the vehicles don't touch each other. The battery that is NOT maintenance-free nneds to have their caps taken off, and a cloth layed over their vent holes. The good battery is the BOOSTER battery, and its black negative cable should be connected to a good ground on the engine block. The other terminal ends of the jumper cable should be connected to the terminal ends of the dead battery. Start the engine using the booster battery. When the engine is running, disconnect the jumper cables.

To jump start any car, you will need to have either a portable jump starter (that look like the ones found here: http://www.autobarn.com.au/products/7/45/3022812/) or have jumper leads which look like alligator clips.

To use either option, attach one side of the jumper cables to to your battery, then attach the other end to another car battery (or in the case of the portable jump starter, it will be already connected with the unit).

Ensure the correct color cable is attached to the correct battery terminal (metal point on battery), i.e. red to red, black to black.

Caution: Car batteries have a high amperage and can lead to electrocution if you touch both metal points on the battery. Always be careful when doing so and if unsure, do not attempt to do so without assistance from a competent individual.
