If this is the problem, remove the connector and clean it. Finally, check the level of the battery electrolyte, the fluid inside the battery. This fluid should reach slightly above the battery plates. If the battery plates are exposed, use distilled water to fill the battery to the proper level. Before attempting to carry out any checks or adjustments on any part of the ignition system, you must ensure that the ignition is switched off.
Contact Points Remove the distributor cap to expose the contact points.
These are the most common cause of breakdown in the ignition system. If the faces of the contact points appear badly pitted or burned, they should be replaced or cleaned. Contact point gaps vary from one model to another, so consult your vehicle handbook. To check and adjust the contact point gap, you must rotate the engine until one of the lobes on the distributor cam has pushed the moving arm of the contact points to its fullest open position. Using a feeler gauge, make any adjustment to the gap by slackening the contact breaker retaining screw or screws and moving the positions of the contact points relative to the distributor base plate.
