Section VIII. Troubleshooting
Vehicle fails to make smoke when engine is running and smoke generator is activated.
(1) Insure shut-off valve is open.
(2) Insure blower motor switch is on (M60A1-RISE and M60A3 only).
(3) Bring engine speed to 1000 rpm momentarily to insure generator output.
Generator output is necessary to close the air cleaner blower motor relay which provides power
to the air cleaner blower motors and the smoke generator solenoids. If air cleaner blower
motors are not operating, check generator output.
(4) Check for fuel running out of hull drains, indicating a ruptured fuel hose of loose
connection.
(5) Check solenoid valves.
With engine running, have someone turn smoke generator
switch on and off. Feel valves to see if they are activated. Check for voltage at valves and
good ground connection.
The solenoid valves can also be checked without releasing fuel into the
exhaust pipes by closing the shut-off valve.
