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?
