[255bayliner]

I have an 87 255 Bayliner that is having some problems. A couple weeks ago someone messed with it and took the shore power out and when I got to the boat the batteries were dead. I got them charged and everything was fine for a week. I went out Saturday and it started right up went out to the raft off switched the battery over to just one so incase it went dead I could switch it over and go but that was not the case. We tried jumping it that didnt work, we tried taking someone elses battery and hooking it up and it still didnt start. I ended up taking a screw driver and arch the starter and it started right up. Got all the way back to the well and it died out(so glad they batteries waited to die at that point when i got home. So I put the shore power on to charge up the batteries and came out the next day and nothing is working. The lights dont go on, the boat wont start, the only thing that works is the tilt and when I look on the MinKota charger it says the batteries are charged. I have no idea what it could be, I thought if the shore power was hooked up the lights would still work and i understand that on Bayliners everything is ran through the batteries so if anyone could give me any ideas that would be great. Thank you for your time on this long thread.

Let's start with some simple stuff - how old are your batteries? What type, i.e. lead acid, gel ,etc.
Also, do you have a radio with preset stations? These are a constant electrical draw.
