The present invention is directed to determining and controlling the appropriate moment at which a combined starter/alternator should transition from start-up mode to alternator/generator mode following an IC engine start-up sequence. The method relies on either belt/chain tensioner position or the position of the belt/chain itself to determine when the IC engine has achieved self-sustaining operation and signal the starter/alternator to transition from start-up to generator mode.

1. A method of controlling a starter/alternator in a start-up sequence of an IC engine driven generating system including belt/chain driven starter/alternator, a belt/chain tensioner, and a starter/alternator controller, comprising the steps of:initiating a start-up sequence of said IC engine by signaling said starter/alternator to operate in starter mode;detecting a first position of a belt/chain tensioner;detecting a second position of said belt/chain tensioner;comparing said first and second detected belt/chain tensioner positions; and,signaling said starter/alternator to transition from start-up to alternator/generator mode when said second detected position is different from said first detected position. 2. A method as in claim 1, wherein:said belt/chain tensioner is a rotary tensioner. 3. A method as in claim 1, wherein:said belt/chain tensioner is a linear tensioner. 4. A method of controlling a starter/alternator in a start-up sequence of an IC engine driven generating system including a belt/chain driven starter/alternator, a belt/chain position sensor, and a starter/alternator controller, comprising the steps of:initiating a start-up sequence of said IC engine by signaling said starter/alternator to operate in starter mode;detecting a first position of a belt/chain;detecting a second position of said belt/chain; comparing said first and second detected belt/chain positions; and,signaling said starter/alternator to transition from start-up to alternator/generator mode when said second detected position is different from said first detected position.
