A.{Mr Adams} MAIN DISTRIBUTOR & CONTACT BREAKER TEST.

Inspection shall be made that the contact points are exactly opposite, with contact surfaces parallel; that the cam runs perfectly true and that the contact breaker lever moves freely on its pivot; which pivot should be greased.

Ascertain that the contact lever spring is free from cracks. The contact lever should be pushed back against the spring as far as possible once or twice without shewing any signs of distress.

Ascertain also that the condenser connecting strip is clear of the condenser case and that the insulated spring terminal is O.K. as regards tension for gripping the low tension wire.

Ascertain also that the various pressure contacts between the condenser terminals and the platinum points are clean and screwed up tight.

Also see that the cam itself is greased.

The tangential force at lever pin radius necessary to advance or retard the ignition distributor shall lie between the limits 1 1/2 to 2 1/2 lbs. weight.

Contd.
