On motorcycles, if this relay is damaged, the
engine can start but will shut down when the start
button is released.
On ATVs, if this relay is damaged or removed, the
engine will run, but damage to a harness diode will
result. When the diode fails, the engine will not run.
Dynamic Test
1. Remove the relay from its harness socket.
2. Using an ohmmeter, connect the positive probe
(+) onto terminal number 86 and the negative
(-) probe onto terminal number 85. Check the
resistance. The resistance should be 1500
± 10%
Ohms.
Reverse the meter leads. If the reading is OL (no
continuity), go to the next step.
If the relay is out of specification, replace the relay
with a new one. If the measured resistance is OK,
go to the next step.
3. Using an Ohmmeter, connect the positive
probe (+) onto terminal number 30 and the
negative (-) probe onto terminal number 87.
Check the for continuity. There should be no
continuity. If continuity is observed, the relay
is damaged; replace it. If no continuity is
observed, go to the next step.
4. Connect 12 V (+) battery voltage to the
number 86 terminal and ground terminal
number 85. There should be continuity
between terminals 30 and 87. If there is not,
the relay is damaged; replace it.
5. Use a voltmeter to verify that there is voltage
present at the wiring harness socket
corresponding to relay terminal 87. Do not
start the engine. If there is no voltage present,
check the main fuse. Use the vehicle wiring
diagram to check the circuit. Take corrective
action.
There are no markings on the socket itself;
use the illustration below for identification.
