NOTE: Overtightening of the insulated terminal clamps will cause breakage.

Battery Specific Gravity

Check specific gravity, using a reliable hydrometer at the scheduled intervals, or more often if there is exces­ sive use of water.

Ignition System

Ignition cables should be kept clean and connected properly. Terminals should be fully seated and the nipples and spark plug covers should be in good condition. To maintain proper sealing between the towers and nipples, cable and nipple assemblies should not be removed from the distributor or coil towers unless damaged or cable testing (refer Group 8) indicates high resistance or broken insulation. Cracked, damaged, or faulty cables must be replaced.

Distributor

All models require 2 or 3 drops of engine oil to be applied to the felt wick under the rotor.

Fig. 5-Felt wick location Ignition Timing

To obtain correct exhaust emission levels and engine performance, the distributor must be correctly positioned on the engine to give proper ignition timing.

The ignition timing test will indicate the timing of the

spark at No. 1 cylinder at idle (only).

Test procedures are as follows:

(1) Disconnect vacuum hose at distributor.

(2) Connect secondary lead of Power Timing Light to No.1 spark plug, red primary lead to positive terminal of battery and black primary lead to negative battery termi­ nal. Do not puncture cables, boots or nipples with test probes. Always use proper adapters. Puncturing the spark plug cables with a probe will damage the cables. The probe can separate the conductor and cause high resist­ ance. In addition breaking the rubber insulation may per­ mit secondary current to arc to ground.

(3) Start engine and set idle to "Specification" (Trans­ mission in Neutral).

(4) Aim power timing light at timing plate. If light flash occurs when timing mark on vibration damper is located ahead of specified degree mark in the direction of engine rotation, timing is advanced. If flash occurs when the vibration timing mark is past the specified de­ gree mark in the direction of engine rotation, timing is retarded. See "Specifications."

NOTE: On models equipped with E.L.B. system, allow a minimum of 90 seconds to pass (after engine start up) before checking timing. This will allow 'Start-up Advance' to decay.

(5) If timing has to be adjusted, loosen distributor hold-down arm screw just enough so distributor housing can be rotated in its mounting. (Moving the distributor housing against shaft rotation advances timing, and mov-. ing with shaft rotation retards timing.)

(6) Tighten distributor hold-down arm screw after tim­ ing has been set and recheck timing adjustment with a Power Timing Light.

(7) Reconnect vacuum hose at distributor.
