this flashes on the info screen every startup then goes away immediately. I am thinking it may be that the PO replaced the alternator with an aftermarket one that doesn't 'read' correctly- i recall someone in another forum mentioning that it was possible to mount the 'wrong' alternator...but the measured voltage is 13.9 at idle. So the alternator is charging fine and the battery starts the engine every time - no lag or drag. Anyone have advice to give? The battery light never comes on btw.
