ELECTRICAL SYSTEM
[1] RELAY
■ Relay
Relay (1) basically consists of relay winding (2) and
mechanical contact points (9).
Current flowing from switch to relay winding (5) cause
“ON (Close)” or “OFF (Open)” of mechanical contact
points (9).
When current is applied to the winding (energized)
(10), a magnetic field pushes the contact lever (8) and
normally open terminal is connected.
Function of relay (1) is to control current to be
controlled in circuit from distant place (switch location
place).
Another function of relay (1) is to control large current
by small current.
function of each relay are as follows.
• Relay 1 : Relay to horn (overheat alarm relay)
• Relay 2 : Relay to start engine (starter relay)
• Relay 3 : Relay to stop engine (solenoid relay)
