Charger not charging 2005 390my

[Steve Hale]

Hi folks, new owner of a 2005 390my. I seem to be having an issue with my progressive dynamics pd2050. When on shore power I sometimes see solid green light indicating boost charge with batteries at 11.9 v. But no amps from output wires to either bank. No amps on analog meter on charger. 12 volts at output but no amps. I swapped the charger with a different one but close cousin known working with same result. I hook charger up directly to batteries and it works. Somewhere in the system it isn’t recognizing batteries. No tripped breakers. Not seeing any fuses outside of breakers on bilge panel. Any thoughts?

Please tell us more about your setup. Do you have a bow thruster? If so, there are typically two separate chargers installed. If you have two, any chance the wiring got mixed up?

Yes bow thruster, a separate charger for that. I am uncertain on the charging status of that one. The survey referenced that it may not be working either. Originally I saw no lights on the thruster charger until I looked underneath and found the led lights illuminating

Steve, looking at the electrical schematics in our owner's manual, it looks like the batteries are connected to the charger on the same "always on" bus bar that serves the bilge pumps, blowers and stereo memory. Any issues you know of on the other systems? If not, perhaps the connection to that bus needs to be investigated. I believe that bus does not go through the solenoids but are they all on just as a check? Does charging seem to be working correctly from the alternators when the engine is on?

 

[Steve Hale]

No issues with stereo, blowers, pumps. Alternators charge fine except starboard tends to jump sporadically from 11-14 until battery is decently charged, it surges in gauges at helm and panel meter. Additionally there seems to be some phantom slow drain on batteries when charger is off. It sinks at about .1 volt per 4 hours until it kills the battery. This is happening to port battery.

I'd say you need to take some readings in the wiring between the charger and batteries. Good news is that the charger, main DC switchboard and batteries are within a few feet of one another. The owner's manual schematics have some good info on which harnesses and bus bars to look at. While you are at it you can look for the stray load on the port system.

Steve, at my boat today and in the ER de-winterizing. I see there is a Battery Charger switch on the main DC panel. I’ve never touched it but assume it cuts off the charger from the batteries if off since charging power is on the AC panel. Have you checked this switch?

Ok I’ll check the manual, how do I go about “checking for the stray load” ? Am I checking every breaker on port side for amps when not in use?

Yes, and the two in the bilge also
