I seem to recall that the Sterling chargers are the same as the Pro-Nautic, but sold under the Sterling brand name in England.

John, Before you change the unit (and if you do, go with the ProNautic 1240P) you should check the fuses. Odds are there are one or two inside the charger (near all the connections) and there should be one in line between the charger and the battery. All the best, Edd ———————————————- Edd M.

House bank is pretty new but when I checked the 2 started batteries(flooded) and 1 was dry as a cork so is that starter battery also shot shot?!! House bank looks fine and holds charge, but all were drained to zero, with dehumidifier fans on for the week. I think Start Batteries are 2017? Guessing charger is shot and this is my problem? What I was getting at is what would be a good replacement for the West Marine 40 amp ? cute little place inside door back against wall in small compartment left of companion way Ughh! how can I check that to be sure as I did’nt see a fuse or anything.

I have a modern charger. ProMariner P-Nautic 1260. Granted my batteries are big and not failing. For unknown reasons I have blown a Xantrex True Charge 40 amp(modern). Refunded under warranty. Could have been bad luck but I'm leaning towards the idea that it is bad engineering. Under the exact same conditions I've never had a problem with the P-Nautic.

I too have never had a problem with the charger in a boat but I have personally killed 4 or 5 of the modern chargers with electronic voltage regulation by attempting to start cars and tractors with the chargers still hooked up. Here is what I think is happening: When the starter relay opens the starter motor circuit, there is a high voltage inductive kick-back from the collapsing magnetic field in the motor that is "clamped" to a lower voltage by the low impedance through a good battery. If because of a bad battery or wiring or whatever that energy is not clamped down to a low enough voltage then it kills the voltage regulator electronics. The rectifier diodes themselves have survived. I have installed a shorting wire around the circuit board in a couple of the affected chargers and they still work but they are anything but regulated now. A suitably large rectifier diode installed across the starter motor could prevent this from happening.

Is it OK or not OK to start your engine while your battery charger is running? I was surprised to see some people say it is not, as people have been jump-starting their car engines for decades, but am interested in seeing what you all have to say on this.
