Umlt cranking 15 to 20reconds to con- 5ewe battery and prevent possible harm to the starter motor Bl. 3. Start Relay K11 has two sets of NO contacts per- forming the following functions when energized: a. One set connects battery B+ to the starter motor shift solenoid B1. b. The other set connects B+ to the fuel solenoid K1 and optional fuel pump El via NC contacts of optional Emergency Relay 'K14. 'If K14 should energize and stop the engine, a brief period Is required for the relay's heater to eo01 before the relay contacts reset to the de-energized position for starting again. , 60 Start-Disconnect Sequence When engine speed reaches 900 rpm, centrifugal switch S1 closes. <strong>This</strong> connects B+ to the Start- Disconnect Relay K12 via resistor Rll. The NC contacts of K12 open the cranking circuit. The NO contacts of K12close to keep B+ (via K14contacts) to the fuel solenoid K1 and the fuel pump El. Stopping Sequence Holding SI1 in Stop position de-energizes K12 which opens B+ circuit to the fuel solenoid and pump. The fuel solenoid shaft forces the injection pump control arm to the no-fuel position. The engine stops from lack of fuel. a
