| SYMPTOM |
CORRECTIVE ACTION |
| When Toggle Switch is flipped to the TEST Position, nothing
happens. |
Check the fuse to make sure it is good. Replace only with SFE
14 fuse. If good, check with a meter to see that battery (+) is present on middle terminal
of toggle switch. Also, confirm voltage is present at terminal 13 when switch is in TEST
position. |
| Starter does not hold in long enough for 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 magneto wiring is
routed in a separate wiring loom from the rest of the control wiring. Also, confirm the
use of shielded cable for the magnetic pickup wiring. |
| Unit will not disconnect cranking after engine has started. |
Adjust the Crank Disconnect pot (R2) to a lower setting.
Confirm that at least 2 Vrms is present from the magnetic pickup. |
| Unit shuts down on oil pressure soon after start. |
Check oil level. Turn up shutdown lockout delay pot (R4) to
increase lockout time and give engine time to develop oil pressure. |
| Unit will not start when remote start / stop contact closes. |
Flip panel mounted toggle switch to the AUTO position. |
| Engine cranks but never starts. |
Make sure your fuel valve circuit is wired to terminal 15. |
| 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. |
Verify the number of teeth on the flywheel and your engine
running speed. Using the following formula 
determine the frequency in hertz your engine is running. Also,
determine the date code and revision number. This information is printed on a sticker
found on the side of the unit. Call
MurCal with this information to further trouble shoot
the problem. |
| Output appears not to function. |
Tighten connections to back of ASM150. Usually a good tight
torque on the screw will solve this problem. You can
verify operation by hooking a lamp to the suspect output. If the light does not come on
when it should, call
MurCal. |
