Started both engines. Both voltages read 12.5 volts. Raised both engines' RPMs. Port voltage goes up, but the starboard goes down. Do engines use battery power when they run?
Gasoline engine uses a little batterypower. Depending if you got electricfuelpump or not. Items that takes power are ignition coil, fuelpump ( if electric) and the sensors. But that is so little power so you shoulden?t notice it in voltagedrop. Might be starboard alternator is going bad and start drawing power from the port engines alternator. Do both alternators go to the same battery. Or do you have one battery for each engine??
One battery bank for each engine. I can combine them all together with a switch but I wasn't using it at the time. Thanks.
