Hi All,

Sorry in advance, this is a long one....... 2007 Rinker 250. Everything with the boat was working top notch until this season. I had the marina install 2 new batteries before launch. Old batteries were pretty old and didn't hold charge well. Everything electrical worked fine on the old batteries.......Now this year, only after they installed the new batteries, there are all sorts of weird things happening.....

Weird thing #1, the volt meter on the shore power panel doesn't work. Shore power works fine, battery charger, tv, ac, etc. all work just fine. The voltmeter just didn't read anything when I got the boat in the water for the first time. Even odder, last time we were up there, I put the boat on battery 2 and now it reads just fine when shore power is connected!

Weird thing #2, the GPS at the help will NOT turn off. You can press the off button 100 times and after about 10 seconds, it automatically flips back on. Never did this before with the old batteries. Worked fine before and now the only way to turn it off (so it doesn't drain batteries when we aren't on the boat) is to turn the "helm power" switch off at the battery switch. That was the solution given to me by the marina which I think is a sign of incompetence frankly.

Weird thing #3, the trim tabs don't appear to be working. Right one seems to work ok but left one shows only going down 1-2 clicks. The buttons have light up little dots that show how low/high the tabs are so no idea if they are actually functioning and those little led lights are screwy or if they aren't working at all.

Weird thing #4, the internal depth finder reads goofy numbers now. When we are in 4' of water, it will say 78.97', 28' of water it will say 2.8 and the alarm will go off, etc. etc.

I had the marina do a diagnostic and they literally didn't look for the problem, they just went to each of the numbered things I listed above, tested them, and then gave me pricing for replacement of entire systems (I.E replacing volt meter, replacing entire trim tab system, replacing entire internal depth finder, etc.).

I think there is something wrong with the battery hookup, grounding wires, the entire electrical wiring setup, etc. but I don't know where to go from here since I am not confident in my marina's service department at all to actually find the smoking gun.

Any help/guidance GREATLY appreciated!!!!

I think Marina connected something wrong and don't want to admit it, because they don't want to pay to fix. Electronics are sensitive and a split second of reverse wiring, kills things

Look real close around the Bats and see if any of the cables or wires have burnt spots on them.

Does the boat have any more wires then just the Battery cables?

And posting the same question in the Rinker section is against the rules.

Sorry, new here and thought I would get different perspectives if it was cross posted. Headed up to the lake this weekend and I am gonna open the engine hatch and do a little digging around the battery bay. I'll snap pics and post to get opinions on battery setup.
