2003 Super Air 210 TE

[dud77]

Back in a SAN after a couple years in a 2005 x Star and glad to be back. Below are pictures of my New to Me 2003 Super Air Nautique TE after a lot of work. Wet Sand and Buff, New graphic, 2008 220 Tower, Ballast Upgrade fly high replacement of tanks, Wet Sounds Rev 3 Some and 4 wet sounds Amps, some interior work. Still have a couple small issues. 1. The Bags drain on their own as I'm riding so I have to keep the valves open (not a big Deal unless I get a loose hose then it would be). 2. Have a low voltage alarm in the dash only when I have a lot of accessories on. New Alternator, Batteries, and ground wire to dash but did not resolve the issue but also not a big deal.

Are the cable connections all clean? No corrosion up the wire at all?

What's your volt gauge reading?

It's 13.0-13.2V at the dash with nothing on in the dash expect perfect pass at idle. When running pumps or lights it drops depending on how many things I have on at idle. For instance if I have all 3 ballast fill pumps on then it drops to 12V or a little less maybe 11.7V. If I only have 1 pump on it drops to only around 12.6-12.8V. If I have more stuff on then it drops down to 11V and I get the low voltage alarm. That being said I still have 13V+ at the batteries in all cases.

These model boats were notorious for having low voltage at the main breaker panel mounted under the dash because of too small a gauge wire running from the battery to the breaker panel. Check the B+ and B- connections at the breaker panel itself to make sure they are tight. The nuts holding them on backed off on my boat years ago causing issues. You may end up needing to run a larger cable from the battery to the breaker panel to solve your problem if it's not related to battery or charging system problems. I think the factory ran a 10-12 gauge wire... A 4-8 gauge may be required.

I ran a 4 gauge ground but didn't know where to run the power wire from. Is it straight off the battery or off a switch somewhere in the engine compartment?

[core-rider]

IIRC, it comes from the starboard battery and runs up the gunwale of the boat towards the dash. Should be a B+ and B-. They will be wrapped up with other wires in loom so you may just want to remove at the terminals and leave the wire. Just run new cables and make them up to the correct terminals. I have never gotten around to doing this project on mine, but want too. I don't have as bad a problem with voltage drop as you though.

Finally got around to running that wire. 13.3v solid now.
