    Finally listened to you all and got a cheap charger at Walmart, 6A charge maintainer, microprocessor controlled, 72W 6amp fast charge 4A medium and 2amp slow 6V/12V automatic.

    Hooked it up and let it sit over night. In the AM the remote unlock didnt work so I knew it wasnt charged. Looked at the charger and it said full charge. I unplugged it and tried to start it, dead. Reconnected, put back to fast charge, it started...the fan revved higher and higher then shut off. I unplugged and reset, put on slow charge, fan stayed low reve so I left it for 2 hours. Came back, said full charge, but was dead.

    Gonna take the cheapie back today

    I have had one for my trolling battery, works flawless for the last 6 months. Just be sure to read instruction book to fully understand maintainer mode and slow charge modes.

    Kinda sounds like you may have a bad cell in your battery.

    pulled all three batts and brought them in, charger is on the starter batt, it kicks in for a few mins, then off for a few, I'll keep checking with the DMM...hope I'm getting somewhere!
