DESCRIPTION:

Yamaha Towny Mj50 Scooter Digital Workshop Repair Manual 1981 Onward

WHEN THE KEY IN “START”  THE ENGINE CAN BE STARTED. When the main switch key is set to START, the start indicator light is turn- ed on by the battery. When the kick pedal is kicked, the fly- wheel magneto turns and the charge coil generates a voltage of 150 to 350 volts which is stored in the condenser in the CDI unit. When a trigger voltage from the pulser coil turns on the SCRI {siliconvcontrolled rectifier), the elect ricity stored in the condenser is discharg- ed to the primary winding of the ignition call.

• This induces a high voltage surge in the secondary winding and produces a spark across the spark plug gap. WHEN THE KICK PEDAL IS KICKED WITH THE KEY IN “START” AND THE THROTTLE GRIP IS OPENED.
• THE ENGINE WILL NOT PICK UP SPEED AND YOU CAN’T START OFF. When the kick Starter is kicked with the key in “START” and the throttle grip is opened, the engine speed will increase slowly.
• But before the engine reaches the speed where the clutch engages, a trigger voltage from the pulser coil turns on the zener dioke (20) which turns on SCRZ. As a result, the voltage from the charge coil is not supplied to the CDI unit;thus no spark is produced at the spark plug.
• As the engine speed decreases, both 20 and SCR2 turn off but the engine keeps on running by utilizing the CDI circuit. By alternating the operation specified above, the engine speed is controlled to 2,300 2 300 r,‘min.
