32v system batteries go dead but alt producing 32v
Hello everyone!!! I own a 1957 71' wooden yacht with three electrical systems on board... a 110v ac, a 12v DC and a 32v dc. My bilge pumps, running lights, some interior lights, and toilets run on the 32v system. I have an awesome charger that does a great job of charging on shore power.
I have a Westerbeke generator that is inop at this time.
Here is my problem... lately when I am running, (two motors, inverter), i notice that the 32v system is rapidly drained. I checked the alternator to see if it was not generating power to charge while that motor (starboard) was running, but it is generating 32v. That is good news in a way... I don't think I have to replace that alternator... but now I have no idea why the batteries would be running down so rapidly. How do I go about searching for the "Vampire" or whatever is sucking these batteries down ahead of the charge coming from the alternator?
I really appreciate the advice. I am keeping the system, so please don't say "Replace the 32v system". Thanks,
