Yeah that's true but I always hook a 12V charger to 2 batteries... You'll never fully charge 16 volts worth but it'll boost them up enough for the charger to recognize them.

Actually...no, I don't know for sure which one I heard. I just ASSumed that it was the relay.

Thanks everyone for the inputs.
I will be back to tinkering with the batteries this weekend and I will post the findings...wish me luck!

I never tried that.... that is a safer way to suggest

I am not sure that Danimal has a voltmeter ..... It is nearly impossible to work on these things without one ..... Can we get an answer on this?

[Danimal]

Yes indeed I do.

Ok...I've gotten the batteries back up with charging in groups of two. Now I know that the carts will move again. Thanks to everyone for giving me some insight and helpful advice.
If I wanted to sell these...what do you think would be the best way to do that (ebay, craigs list...), and how much should I ask for them?

I almost forgot to mention that the chargers were not the problem. Once the batteries were up to the 70% range, the OBC allowed the charger to turn on again.
