The engine started fine in Nov when I winterized it. Yesterday I wanted to just bump the starter to get the grease fitting on the coupler where I could get at it to grease it. Turned the key get the horn, no click of the solenoid nothing. All gauges work,lights, stereo, blower, bilge pump,everything but engine won't crank. Battery terminals are clean and tight. Put charger on it in 125Amp start mode. Jumped across the 50amp breaker still nothing. Anyone have any ideas.
