Starter Relay
z Apply 12V to the terminals and check for continuity
between the positive and negative terminals using a
multimeter.
z If the starter relay clicks and continuity is found, the
starter relay is OK.
z If there is no continuity when without the 12V, the
relay is OK.
Note: Do not apply the battery voltage to the starter relay
for more than 2 seconds. This may cause overheat and
damage the relay coil.
z Measure the coil resistance between the terminals
using a multimeter. If the resistance is out of the
specified value, replace the starter relay with a new
one.
Set multimeter to 1x10Ω position
Starter relay coil resistance: 3-5Ω
Auxiliary Starter Relay
z Apply 12V to starter relay positive and negative
terminals and check for continuity between A and B
using a multimeter.
z If the starter relay clicks and continuity is found, the
starter relay is OK.
z If there is no continuity when without the 12V, the
relay is OK.
Set multimeter to 1x100Ω position
Auxiliary starter relay coil resistance: 90-100Ω
