Abstract
A start timer circuit for a diesel engine is responsive to the operator actuated start switch. The timer circuit energizes the engine start motor circuit for at least a minimum time, sufficient to avoid sustained firing of the engine at a low speed. Safety circuits prevent false energization of the start motor circuit in the event of malfunction or failure of various circuit components.
