low voltage / Not charging (Super Air Nautique 210 model year 2007)

[slundsgaard]

Hi,

I have a problem with my boat (Super Air Nautique 210 model year 2007).On the panel i got the alert 'low voltage' from time to time.
The boat can start but when I look at voltage it says 11.9 volt running on one battery and 12.1 running on the other battery.
When i look in the manual it say it should be above 12.5 at any time. The batteries should be ok an so should the 'charger'
Do you have any ideas what could be wrong?.

Any idea is apriciated.

Thx

Does it do it on both batteries? Do you have a batt selector switch? How old are the batts? Are you blasting stereo when this happens?

[slundsgaard]

Hi,
yes it does it on both batteries. I have a batt selector switch and when switching to first bat the voltage says 11.9 volt and when i switch to secon bat it says 12.1 volt. When switching to use both bat at the same time it says 11.9 volt. The batts are around 2 years old. The numbers 11.9 and 12.1 is without using stereo and only with the engine without sailing.

I have a similar problem on my 2006 ski 216. I believe I have it narrowed down to my keyless key pad. Check your voltage at they battery, and at other various points (12v receptacle, starter motor, alternator, etc.) I found my batteries are 12.8 and everyhting is getting the full voltage except the dash panel and the 12v receptacles. I messed around for a while and figured out when I press the horn button the voltage alarm on the dash goes on and off...and reading vary from 10.5 to 11.1. However it seems to be a false reading, as both batteries are full. I believe it may be a bad keypad.

Well, it wasnt the keypad. i replaced it today, same low voltage warning on the tach gauge. Any suggestions on what to check next?

I'm chasing this same issue on my 07 210, and all the threads seem to end like this one, with no resolution... cluster reads 9ish volts with engine off, goes up to 10.5ish while running and at speed. Taking readings at batteries and at the dash shows 12+ with engine off and 14+ while running. I've read about issues with the 3-way switch, but wasn't able to get to the connections before I ran out of time today. Cleaned up connections to dash, and the wire gauge looks fine which seemed to be an issue on earlier boats.

Seems to me either signal coming from gateway or maybe the tach itself is bad. Any one have resolution on these low voltage warnings? I can hear the beeping when I go to sleep at night...

Crimedog, did you ever figure this out? I am having the exact same issue on my 2008 210. I am chasing my tail around in a circle trying to figure this out!

[crimedog]

I worked with the guys from Faria, who were great btw, on the phone for a few days, to the point where all of us were out of ideas. I ended up getting the replacement gauges below. They take some attention to detail installing, but once I got them all sorted out they were great all last year. The speedometer was off from the perfect pass, but I think I may have missed a setting on the back of the gauge, plus the perfect pass is all I really care anyway anyway....

It ain't cheap, but that cheaply made gateway isn't going to last forever, and they are obsolete. Also, I may have posted the wrong link, but you get the idea, call the guys at NP they'll hook you up...

It could be a ground wire/connector somewhere getting old and dirty and corroded.

It was a know problem with the early Nautiques, there is a significant voltage drop between the battery and the dash. A lot of times Perfect Pass would complain of low voltage. Try running a 10 or 12 guage wire to the fuse block from the battery and see if that brings up the voltage. Many people, including myself, have run a separate wire to the fuse block to fix the problem.

Thanks for the help and feedback on this. i will definitely call Faria as a next step. I am hoping it isn't the gateway going bad. I have seen posts on others opening them and cleaning the internals. The greatest challenge with this setup is that there are not clear ground and power connections going to the instruments like the old style gauges. They are all connected through the gateway. I attempted to measure the voltage going in the gateway bus with a multimeter but cannot get a good reading on the four pin connection as it is the internal type. I will test it on the data and power cable leaving the box and hopefully get some sort of useable reading. This is a picture of what I am working with.

I live in fear of the Faria failure. :/

BTW, is this a 'the system is not charging' issue or is this a 'the gauge is not correct' issue? As I read it, it's seems to be the latter.

Assuming it is a 'gauge not correct issue' and it was my boat, I'd start by getting some contact cleaner and enhancer (like this) and clean out every single connector in the system. The cheap (and lucky) solution is some connector not being quite up to to snuff via corrosion or dirt the contact cleaner being enough to fix it.

If spraying the connectors doesn't do it, then I'd consider going to the next stage...opening the box and gauges and blowing them out with the same product.

Curious how it turns out.

I’m having what appears to be this exact problem on my 03 SANTE. Can anyone elaborate on this alternative wire to the fuse block? What fuse block are you referring to? Any info would be greatly appreciated. I have sufficient voltage everywhere tested except the dash. Thx

Under the helm on the kick panel is the fuse block. You can do one of two things. Run a separate wire from the starboard battery to the fuse panel + connection (should do the negative too) or run a separate wire to the flip switch next to the drivers set and then to the fuse block.
