Hei jeg løfter dette med uren strøm/støy i kabler og magnetfelter ,så jeg legger med en bulletin på mercruiser 3.0 MPI .
Min erfaring er at denne bulletengen også gjelder for din motor,og kan gi motorfusk.Texten er på engelsk,men håper det går greit.
MCM 3.0L MPI EC Battery Cable Routing Models Affected Models Covered Serial Number or Year MCM 3.0L MPI EC All Scope Worldwide Situation An electromagnetic field is created when current passes through large‑gauge current‑carrying cables. If these cables are located too near the crankshaft position sensor, they will affect the sensor's signal and adversely affect engine performance. Therefore, engine battery cables and other large‑gauge current‑carrying cables must not be routed closer than 46 cm (18 in.) to the front of an MCM 3.0L MPI EC engine. Cables mounted closer than this to the crankshaft position sensor will result in engines failing to start, misfiring, or performing poorly. Inspection/Correction When diagnosing a running issue on a MerCruiser 3.0L MPI EC engine with one of the symptoms listed above, ensure that both the positive and negative battery cables are at least 46 cm (18 in.) from the crankshaft position sensor or the front of the engine. Also, ensure that the battery ground cable is attached to the rear of the engine on the ground stud. Refer to the installation manual or service manual for identifying the proper location. Note that attaching a ground cable to the front of the engine will position it closer than the required minimum distance of 46 cm (18 in.) from the crankshaft position sensor, and will result in the engine failing to start, misfiring, and performing poorly. Additionally, the negative and positive battery cables should be routed together (paired) when possible to balance and reduce the disruptive effects of either cable's electromagnetic field
