9/27/01 AC 43.13-1B CHG 1 checklist for isolating some of the malfunc- tions inherent to ignition harnesses. a. Carefully inspect the lead conduit or shielding. A few broken strands will not affect serviceability, but if the insulation in general looks worn, replace the lead. b. When replacing a lead, if the dressing procedure is not accomplished properly, strands of shielding may be forced through the conductor insulation. If this occurs, a short will exist in the conductor; therefore, it is es- sential this task be performed properly. c. The high-temperature coating used on some lightweight harnesses is provided for vibration abrasion resistance and moisture protection. Slight flaking or peeling of this coating is not serious, and a harness assembly need not be removed from service because of this condition. d. Check the spark plug contact springs for breaks, corrosion, or deformation. If pos- sible, check the lead continuity from the dis- tributor block to the contact spring. e. Check the insulators at the spark plug end of the lead for cracks, breaks, or evidence of old age. Make sure they are clean. f. Check to see that the leads are posi- tioned as far away from the exhaust manifold as possible and are supported to prevent any whipping action. g. When lightweight harnesses are used and the conduit enters the spark plug at a se- vere angle, use clamps as shown in figure 8-8 to prevent overstressing the lead. 8-19. MAGNETO INSPECTION. When- ever ignition problems develop and it is deter- mined that the magneto is the cause of the dif- ficulty, the following are a few simple inspec- tion procedures which may locate the mal- function quickly. However, conduct any inter- nal inspection or repair of a magneto in accor- dance with the manufacturer’s maintenance and overhaul manuals. a. Inspect the distributor block contact springs. If broken or corroded, replace. b. Inspect the felt oil washer, if applica- ble. It should be saturated with oil. If it is dry, check for a worn bushing. c. Inspect the distributor block for cracks or a burned area. The wax coating on the block should not be removed. Do not use any solvents for cleaning. FIGURE 8-8. Typical method of clamping leads. d. Look for excess oil in the breaker compartment. If oil is present, it may indicate a bad oil seal or bushing at the drive end. This condition could require complete overhaul, as too much oil may foul and cause excessive burning of the contact points. e. Look for frayed insulation on the leads in the breaker compartment of the mag- neto. See that all terminals are secure. Be sure that wires are properly positioned. f. Inspect the capacitor visually for gen- eral condition, and check the mounting bracket for cracks or looseness. If possible, check the capacitor for leakage, capacity, and series re- sistance.
