I was using a lithium ion battery which open shorted during operation . I replaced the rectifier and the battery back to a regular lead/acid type and all was fine for a little while . Now I have a "no crank , no start" and the trim does not function . The battery voltage is 13.2vdc . The motor is a 2011 20hp 4stroke Merc w/ a 4000 gen 2 remote control box . I can't remember if there is a OEM fuse inside the control box or not . I had also contemplated if the switch box was damaged . But , does the switch box relate to the starter and the tilt function ? All other electrical is operational . When the ignition switch is turned to the on postion I have power from the control out (turns on instrumention) , if the fuse in the box blew I figure it would not power the instruments ? If the ignition is turned to "on" I can bypass the the starter relay at the motor and the starter cranks . It seems I'm going to have to open the control box trace the current through the components ...PITA for sure .

Any insight would be apreciated .
