EXHAUST VALVE RELAY
TESTS
The exhaust valve relay module controls the
exhaust valve actuator.
Operation
When the outboard is running, the fuel pump cir-
cuit (purple/black wire) provides 12V to activate
relay 3. Relay 3 provides fused 12V (red/purple
wire) to relay 1 and relay 2.
The EMM controls the exhaust valve by grounding
the blue/black wire.
When the blue/black wire is NOT grounded, fused
12V is supplied to the exhaust valve actuator
through the orange/red wire and the actuator is
grounded through the black wire on relay 1.
When the blue/black wire IS grounded, relay 1
and relay 2 are activated. Relay 2 supplies fused
12V to the exhaust valve actuator through the red
wire and the actuator is grounded through the
orange/red wire.
