2015 242 limited S charging issues.

[Richard Lajoie]

2015 242 limited S, anyone with charging issue. Typical day, went out for a 25 mile ride. Battery started at 12.3 volts, by the end of the trip volts where down to 11.6. That is very typical for my boat, anyone else out there with issues. By the end of the weekend my low voltage alarm is going off and that is every weekend. I haven't even updated the stereo yet.

Your batteries are likely fine and so is the charging system. Test the batteries with a voltage meter to verify but the 15's have a known issue with the connect system displaying in accurate voltages.

@Richard Lajoie see the thread below. Lots of good info by other members regarding charging system.

This is usually due the someone connecting the small black wire to the DVSR to a positive terminal or not connecting it at all. The low voltage is probably the house battery and without that little black wire connected the relay will never switch over to charge the 2nd battery.

No, I check them everyday. The connext system is spot on with my meter.

Are you getting 2 different voltage readings on the conext display. If so you have the only working system. The 2 readings are usually within a 10th or 2 of a volt on the display but they are both the voltage of the house battery. They don't show the starting battery voltage correctly when checked at the battery.

I had wanted one of these with my bay boat but never did so I put one on my Yamana when I got it. Keeps them running perfect every time at less than the cost of one replacement battery. I just keep it plugged in so keeps them in tip top shape. http://www.minnkotamotors.com/Products/MK-210D/

I second this answer. Check the tiny black wire that goes from your house battery negative to your DVSR (unit that doesn't have a red switch). Had a passenger throw a fender in the battery compartment and it came loose from the back of the DVSR.

I had a bad DVSR from the factory on my 2015. If both batteries charge with the 'parallel' selector thrown then you have an issue with the DVSR.....either an improper connection on the small wire or the DVSR itself.

Any update? Did you find the problem?

I also have a 2015 242 Limited S. I believe at least my house battery is not being charged when the engines are running. Originally had a bad battery, but I replaced it. It seems like my starter battery is OK. How do I check the battery charger? I have attached a photo of my wiring. Is the DVSR supposed to be connected to the house battery or the starter battery? Mine is connected to the starter battery. Any help would be appreciated.

This is a link to the description of how the DVSR works.

Once the start battery or the house battery reaches 13.4 volts this little red light comes on indicating the DVSR is active. Connecting the DVSR ground wire to the start battery is fine, however the DVSR ring terminal should be on top of the other terminals, ABYC standards are that the larger cables and their connectors go on the bottom.


Just checking, you have both the house and start batteries turned on during operation correct?

Once the engines are running, on your connext screen you should see the voltage on the start battery increasing, once the start battery reaches 13.4 volts, which will probably read less on the connext screen, the voltage will drop as the DVSR is on, check the indicator light, and is charging your house battery too. Use a good quality multimeter to c double check voltages.

It doesn’t appear you have an onboard battery charger, you need to have a good onboard charger that has 10A per battery. The charging systems on our boats are too small to charge batteries fully. Due to the way the DVSR operates, it will close while the batteries are being charged, this can easily be corrected so the batteries charge independently.

Also it looks as if there is a film on top of your batteries, this can allow voltage to flow between the terminals discharging the batteries, I suggest you clean your batteries and terminals and put dielectric grease on top of the cleaned and properly attached connections, you don’t want dielectric grease on the contact surfaces of the batteries or cable connectors.

Thanks, I’m going to read up on this. The onboard battery charger uses the engine power to charge the batteries? I guess I don’t understand it unless it’s run by a belt or something.

 

[FSH 210 Sport]

No, the onboard charger is plugged into 120VAC at your house, shop, dock etc.

That’s what I thought. I have no way to charge at the storage place. There are no outlets. I need to remove the battery to charge at home.

Okay then you can set your batteries up with quick disconnects to make it simple.
