(4) Relays
Starter Relay and Engine Relay
1. Remove relays (1), (2).
• Starter relay and engine relay are using same relay. When
checking, be sure to check the color of wiring harness.

Checking Connector Voltage
1. Measure the voltage with a voltmeter across the terminals
following table below.
2. If the voltage is different from the battery voltage, battery, slow
blow fuse, fuse or wiring harness is damaged.

Checking Coil Resistance of Relay
1. Measure the resistance with a ohmmeter across the terminal 1
and terminal 2.
2. If the resistance is remarkably different from the following table
or there is no resistance, the relay is damaged.

Functional Check
• The relays described here are used same ones so that
these are interchangeable.
1. Apply the battery voltage across the terminal 1 and 2, and check
for continuity across the terminal 3 and 4.
2. If continuity is not established across the terminal 3 and 4,
replace it.
