Justbass11 Posted April 23, 2020 Posted April 23, 2020 I forgot to unplugged my boat, which would be ok if a big rain storm did come by. The inside of my boat was full of water and I didn’t realize this until days later. Now my 2 bank battery charger tripes the gfi plug. Fuses are ok, my question is this, is it time to buy a new charger? The one I have is about 4 1/2 years old. All input are welcome...thanks ps I’m going fishing this Friday...I hope 1 Quote
Super User jbsoonerfan Posted April 23, 2020 Super User Posted April 23, 2020 How long has it had to dry out? 1 Quote
Super User slonezp Posted April 23, 2020 Super User Posted April 23, 2020 I would hope a marine rated charger wouldn't get damaged by water. A stated above, has the boat dried out? Maybe there is a connection somewhere that is causing a short from the moisture. Quote
Super User NHBull Posted April 23, 2020 Super User Posted April 23, 2020 Not unusual for a gfi to do that, heck I have one that trips when I plug in a leaf blower. Plug it in a normal outlet....it is still fuse protected Quote
Justbass11 Posted April 23, 2020 Author Posted April 23, 2020 @jbsoonerfanit been a few days to dry out. @slonezp it seems to have water or moisture it it. Quote
Global Moderator TnRiver46 Posted April 24, 2020 Global Moderator Posted April 24, 2020 I suck at inboard chargers. I use a $20 3 amp charger instead. When one battery is full, hook it to the next one Quote

Expand I do have a big battery charger on wheels if for whatever reason I need to charge something up really quick if a battery somehow went all the way dead. I’ve always referred to it as the defibrillator 2 Quote
Super User WRB Posted April 25, 2020 Super User Posted April 25, 2020 Don't charge deep cycle marine batteries using 200 amp quick chargers. Dry out the onboard charger if possible using a hair drier, it's not submersible it's water resistant. Take the charger out of the boat and inspect it for any moisture inside. Shake it hard, turn it over etc. Test it on the bench not connected to any batteries for shorting. Hook up one battery to a bank lead and try it, test each bank. If it works on the bench reinstall it. If not....you need a new charger. Tom 1 Quote
HenryPF Posted April 26, 2020 Posted April 26, 2020 If the bench test works - babysit your battery charger and check on it. Nothing like seeing it work for 5 mins and it goes out 10 mins later and you have batteries that are not fully charged. New 2 bank charger at 5amps each bank is only like $75 after $25 rebate from Minn Kota. Minn Kota MK-210D Minn Kota Battery Charger Rebates 1 Quote
Justbass11 Posted April 27, 2020 Author Posted April 27, 2020 I took out the two bank charger and am monitoring it now and will see what happens in the morning. At least it’s not tripping the gfi. I do have it hooked up to 2 batteries. So far all seems ok. Quote
