Lestronic II charger kicks off after a few minutes

[matt1382]

So I got an 87 DS in, batteries were mixed batch and at about 3v each after sitting for a long time. I was able to bring them up to 6v each with an auto charger. Hooked up the lestronic and it wouldn’t work. Took off the cover and there was a broken wire, so I fixed that. Now it will come on when I plug is in, I can hear the charger humming. But the output only shows a couple amps and then kicks itself off after a few minutes. I’m assuming that I’m just going to have to replace all the batteries? They all load tested fine, and I don’t mind replacing them but I was hoping to be able to make sure the cart actually moves before replacing the batteries.
