Power Supply Cut-off Relay
717 Engine
The relay is located in the cover of the electrical
box.
First ensure the DESS switch works properly (see
testing procedure further).
Test the signal wire (BLACK/PURPLE) to the pow-
er supply cut-off relay as follows:
Disconnect the connector on electrical box.
Using a voltmeter, perform the following tests:
Connect test probes to the small RED wire on
the starter solenoid and on the RED/PURPLE wire
from the cut-off relay. Reading should be 0 V. Oth-
erwise, replace the cut-off relay.
Keeping the test probes on the same wires, con-
nect a jumper wire between the BLACK/PURPLE
wire from the cut-off relay to the battery ground.
Measure voltage. Reading should be 12 V. Oth-
erwise, check wiring and if it is good, replace the
cut-off relay.
If there is no current supply to the electrical com-
ponents while the DESS switch and the cut-off
relay test good, check the wiring harness and
connections. If everything test good, the MPEM
couldbesuspected.
Engine Start/Stop Switch
Disconnect start/stop switch connector. Measure
resistance between switch wires as per table.
NOTE: On 3D models, check both switches one
at a time.
