Battery relay & Safety start relay
1. Battery relay
This is main relay for electric system.
The relay turns the battery current ON or OFF, according to low power signals received from the start
switch. Use of the relay permits the start switch to control the power of the batteries with a small capacity
wire.
When you replace this component, pay attention to the +/- signs on the relay.
Wrong connection can cause early failure of relay.
2. Safety start relay
When trying to restart the engine while the engine is running, or if the start switch is in the START position
after the engine is activated, the relay cuts off the current to the starter motor to protect it.
