12 Electrical System
12-21
12.12.2 STARTER RELAY
Put DC12V between positive and negative
terminal. Use multimeter to check
connection between 2 contacts.
If multimeter clicks, there is connection.
If DC12V is removed,no connection
between contacts.
If both above 2 items are proved, it
indicates the replay is good. Turn
multimeter to DIODE.
NOTE: The voltage loaded between
terminals can not exceed 2 minutes.
Otherwise, starter relay may overheat
or burn.
Use multimeter to measure the start relay
coil resistance.
If the resistance is out of standard, replace
with a new one.
Turn multimeter to 1×10Ω
Start auxiliary relay resistance: 3Ω~5Ω
12.12.3 Start Auxiliary Relay, Fuel Pump
Relay
Put 12V between auxiliary starter relay
positive and negative terminal. Use
multimeter to check the continuity between
A and B.
Turn multimeter to DIODE.
If multimeter clicks, it indicates there is
connection between A and B.
If 12V is removed, no connection remains
between contacts.
If both above 2 items are proved, it
indicates the replay is good.
Turn multimeter to 1×100Ω to measure the
relay resistance.
Auxiliary starter relay resistance:
90Ω~100Ω
