TM10-3930-660-20 5-3. FUEL SHUT-OFF SOLENOID - TEST (Cont’d) Be sure starter switch is in OFF position during step 1. 1. TEST RESISTANCE OF FUEL SHUT-OFF SOLENOID  (1). Electrical leads (2) are connected together with a jumper strap. DO not remove jumper strap when disconnecting electrical leads (2) for this test. a. b. Disconnect female spade connectors of two electrical leads R and 07 (2) from male spade connector of solenoid  (l). Place one probe of ohmmeter at terminal (a) of solenoid (1). Place other probe of ohmmeter at engine  ground. Ohmmeter should read 29.5 ohms +/- 2.5 ohms during test in step lb. If ohms reading is not within acceptable limits, solenoid (1) requires replacement. Notify direct support maintenance. C. Connect female spade connectors of two electrical leads R and 07 (2) to male spade connector of solenoid (1). Be sure auxiliary fuel shut-off switch is in the ON position during step 2. 2. TEST CURRENT DRAW OF FUEL SHUT-OFF SOLENOID  (1). a. Position clamps of ammeter around electrical  leads  (2) b. Have an assistant turn the starter switch to the ON position without starting the engine. Ammeter should read approximately one ampere when starter switch is turned to the  ON  position. If reading is not correct, solenoid (1) requires replacement. Notify direct support maintenance. 5-3
