We have found the weak link - and as it turns out so have many others - in the otherwise very reliable Volvo Penta D2-40 Diesel. Nothing happened when we we tried to start our new motor. Dead as a door nail. And, we were in a very beautiful but isolated spot with no cell or VHF coverage - Pt Baker, Alaska. After a day of tinkering we figured out that we were able to jump start the engine by bypassing the computer control box and running a wire directly to the starter from the battery. It worked! The bad news is that we did not have any instruments or means of starting or stopping except manually and had no exciter to drive the alternator. Thank goodness for our solar panels!
