Well, I have been away from the boat for about two weeks, and I stopped by it today. I didn't have much time to spend at the boat due to having to catch a flight out of town for work. So, I get to the boat, and I notice that the battery meter inside the cabin wasn't reading any voltage. So, I flipped on a few of the dc breakers and I find out I have no battery power. So, I take my volt meter and jump down and measure the battery voltage. The furthest one forward reads 12.8volts. The two located behind that one each read only 2.8volts. These are brand new batteries that were just put in on July 7. So, something must of drained them while I was away from the boat. I find out the hard way, that I should turn off the battery switches when I leave the boat.
Ok, this is my question, so I flip on the converter switch, since I am plugged into shore power. I jumped down and looked at the Professional Mariner flyback 20-3 battery charger. The LED light on it was red, but I noticed it pulsing a bit, from a duller red to a brighter red. Keep in mind this if the fist time I have used the converter, so I don't know if this is normal. I stuck my volt meter on the two batteries that were dead and then the red LED light would go from the duller red to the brighter red for about a second at a time (a second on and off, and that repeats), and on my volt meter the batteries would read from 2.8 volts to like 3.1 volts.
So, is this normal? Is the battery charger running some type of a trickle charger or a self load test on the battery before it will charge it? I didn't have much time, so I left the converter on and I had to run to the airport. I hope this was safe to leave on. What do you think? The charger is working normal? Or is something wrong with the unit? Also, the ammeter on the charger was always on 0 and it didn't move. I won't be back till Thursday evening, so I am kind of worried about leaving this on while I am away.

I know I didn't wait 2-3 minutes before reading the voltage, so maybe this is was my problem :smt100you may have to wait 2-3 mins before charger "kicks in"
