When starting a MEP 806B, how long do you hold the engine control switch in the start position?

When starting a MEP 806B, it is crucial to hold the engine control switch in the start position for 2 seconds to ensure that the starter motor has sufficient time to engage the system and initiate the engine start sequence effectively. This duration allows for proper fuel delivery and ignition to take place without excessive strain on the starter motor. Holding the switch for this specific time frame helps prevent potential damage to the starter, which can occur if the switch is held for too long or not long enough.

The importance of this timing is underscored by the need for a balance between sufficient engagement for a successful start and the avoidance of over-cranking, which could compromise the starter’s lifespan and overall system integrity. The other time durations listed would either be too short, not allowing enough engagement for a successful start, or too long, risking damage to the starter mechanism.
