I have a 77 240 SDA with twin 470's. The port engine amp gage seems to be pegged over and doesn't move at all when the engine is runnning. Checked the voltage output at the battery and it seems to be putting out power and increases as you increase rpms. Not to sure on what it is suppose to put out as it is one of those Mercruiser charging systems that uses some type of coolant cooled system not a alternator. The starboard engine gage works great.
