Specifications

Low Oil Sensor

This sensor must use a #194 bulb, resistance of the

bulb MUST be .27 ampere in series with the sensor

for proper operation and to prevent sensor damage.

Remove the sensor from the engine and attach the

electrical plug. Attach a jumper lead from an engine

ground to the threaded portion of the sensor. Place

the keyswitch in the run position. The indicator light

should come on with the tip of the sensor in air

(uncovered) and go off when oil covers the sensor

tip. The response time of the sensor is between 5

and 15 seconds with 13 volts D.C. at the battery.

Lower battery voltage will result in a longer response

time. Use teflon-type pipe sealant on the sensor

threads to prevent oil leakage when reinstalling

(diag. 60).

SINGLE

Fuel Shutdown Solenoids

If the engine is running, the solenoid can be checked

by removing the electrical plug-in at the base of the

solenoid. Almost immediately the engine should

shutdown, if not replace the solenoid (diag. 61).

Test the solenoid off the carburetor by applying 12

volt D.C. from the battery positive terminal to a

solenoid terminal. Connect a jumper wire from the

metal housing (or other terminal) to a negative

battery terminal. The plunger should retract the full

travel distance. Disconnect the negative jumper lead

and the plunger should return to the extended

position. Replace if necessary (diag. 61).
