C. Self-canceling flasher system 1. Description The self-cancaling flasher system turns off the turn signal after a period of time or distance involved in turning or changing lanes. Generally, the signal will cancel after either 10 seconds, or 130 meters, whichever is greater. At very low speed, the function is determined by distance; at high speed, it is determined by time. At low speed, especially when changing speeds, the canceling determination is a combination of both time and distance. 2.
4. Inspection: If the flasher self-canceling system should become inoperative, proceed as follows: a. Pull off the 6-pin connectar from the flasher canceling unit, and operate the handle switch. If the signal operates normally in L, R, and OFF, the following are in good condition: 1) Flasher unit. 2) Bulb. 3) Lighting circuit. 4) Handle switch light circuit. If (1) through (4) are in good condition. the following may be faulty: 1) Flasher canceling unit. 2) Handle switch reset circuit.

*ELECTRICAL A. IGNITION SYSTEM 1 Rlneb r4irrnram 1 protective circuit 2. Description This model is equipped with a battery operated, fully transistorized breakerless ignition system. By using magnetic pickup coils the need for contact breaker points is eliminated. This adds to the dependability of the system by eliminating frequent cleaning and adjustment of points and ignition timing.
turned on and the crankshaft is not turned, the protective circuit stops current flow to the primary coil within a few seconds. When the crankshaft is turned over, the current is turned on again by the signals generated by the pick-up coils. NOTE: Even though two spark plugs fire at the same time only one cylinder is on the compression stroke at a time. The other cylinder is on the exhaust stroke and the spark in that cylinder has no effect.
