TROUBLESHOOTING INFORMATION
WARNING:
Make sure voltage and current requirements are within the ASM160 ratings. Determine the polarity for the applica-
tion. Use appropriate wire size for voltage and current. Do NOT route/bundle AC POWER wires with any other wiring.
These instructions will assist in the correction of most problems which you may encounter with the unit. Before checking the
list, first check all wiring and connections. If problems persist after the checks, consult any Murphy facility.
SYMPTOM
CORRECTIVE ACTION
When Test - Off - Auto Switch is placed in the TEST
Position, nothing happens.
Check your fuse to make sure it is good. Use a SFE 14 fuse. If good, check with a meter
to see that battery (+) is present on middle terminal of toggle switch. Also, confirm volt-
age is present at terminal 10 when switch is in TEST position.
Starter does not hold in long enough for the engine
to start.
Unit is possibly seeing a voltage drop. Ensure that battery is hooked directly to unit,
14 AWG wire is used, and no short circuits are present. Also make sure that the crank
disconnect pot (R2) is turned up high enough.
Odd, erratic behavior is noticed.
Check to ensure that all alternator and ignition wiring is routed in a separate wiring loom
from the rest of the control wiring. Also, confirm the use of shielded cable for the mag-
netic pickup. Resistor type spark plug wires and/or RF type spark plugs may be neces-
sary for spark ignition engines.
Unit will not start when remote start / stop contact
closes.
Unit shuts down on oil pressure soon after start.
Move panel mounted Test - Off - Auto switch to the “AUTO” position.
Check oil level. Shutdown lockout delay pot is fixed at 15 seconds to give engine time to
develop oil pressure.
Engine cranks but never starts.
Make sure your fuel valve circuit is wired to terminal #1.
Engine starts but green light blinks on briefly
then goes out for 35 seconds. This occurs the
same number of times set for crank attempts.
Engine is then shutdown on Overcrank.
Check to ensure Crank Disconnect adjustment is properly set. Refer to “Crank Disconnect
(R2 Pot)” paragraph on page 3.
Output appears not to function.
Tighten connections to back of ASM160. Usually a good tight torque on the screw will
solve this problem. You can verify operation by hooking a lamp to the suspect output.
