Van here. I have a question which requires a solution. I have a 1994 Voyager Pontoon boat. The nature of the problem is the dash board guages are fluctuating at engine idle and when i apply increased power. Now I have replaced wiring on the engine (needed it anyways as it looked melted) tested the grounds and replaced some ill looking bullet connectors. I still am getting same problem at the dash. When I turn ignition on to acc and not full start the guages set at their appropriate areas and do not fluctuate; again only does this when i turn it all the way on. Any assistance wouyld be helpful. Thanks.
