The protection method and circuit provide a time delay after a first contact with the power source is made until full power is allowed connection to the trolling motor. This time delay is longer than the “bounce” time, or the time a user may “bounce” a contact on and off of a battery terminal, during a typical batter connection. Therefore, this delay prevents sparking at the battery terminal. During the time delay, an initial pre-charge brings the main capacitor's voltage up to the battery voltage in a low stress, no spark process prior to being connected directly across the battery source terminal by relay contacts. |
