and if it sees 64.5 volts then it should be turning the charger off
This is why I think the C C charger with OBC is a piece of junk. It looks like the CC charger has 3 stages of charging. First is the bulk stage, full scale 15A. The second stage would be the absorption charge at about 5A which should end at about 57.5V. What it does is go into the equalization charge and take the voltage up to anywhere from 61V to I've seen my meter as high as 66V. This equalization charge is necessary, but not every time you charge your battery. I read that it should be done once every 2 or 3 months. Depending on how many times you run your batteries completely down. The way I'm looking at this is once the batteries get above 57.5 the charger isn't charging anymore all its doing is converting the water(acid) into hydrogen and oxygen. This is why you have to add water to the batteries every week. If only there was a way to reprogram the OBC to 57.5V cutoff. Then half the OBC and charging problems would go away.

I have yet to see my charger start at 15A. Usually it's right around 7-8A.

Since that is at half power I would suspect that the power supply is half waving. A bad rectifier causes that. Or now this is a big IF, if the transformer is center tapped one half a winding could be open.

I'll look into that and test the rectifier for starters. I assume the procedure is in the charger manual?

Hi, fngcarter. I just might by accident have kicked my charging system back to working as it should. Have a look at my today's posting on my thread 'My 2001 DS won't stop charging' for details. My charger is a Powerdrive 1 rather than your Powerdrive 2 but what I did might be worth a try for you.

Whether the solution to my problem is permanent remains to be seen.

Well I tried your technique peter w and so far nothing has changed. I'll keep checking it though periodically.

I don't know if my charger is supposed to turn on then off and back on or not, but it's not. Lol my cart is an 02 ds series cart. Another thing is I took the amber lens off the battery warning light and noticed out of the two? One of the bulbs looks burned out. Didn't know there were two in there. Huh?...one looks like an led of some sort and the other like a small thin bulb(the burnt one). Anybody know what those are for? I ordered another one today.

. . . the battery warning light also serves as a point where the computer can be read by a hand held scanner for trouble codes by the dealer . . .

If a person was thinking about doing away with the OBC and going with a DPI charger we would be looking to order the 17 amp charger that was supposed to be used with the carts that do not use an OBC correct?

Teecro, I looked on the DPI web site and seen that have 3 maybe 4 chargers that are listed as compatible with the Club Car. I would think that you are right in that you would need the one for cart w/o an OBC because we would be removing it. ScottyB has only one listed but he doesn't have a part number listed as to which one he is selling. I would like to buy it from him just because of the online support he would provide, but I'd like to know what I'm buying. Hopefully he might see this and clarify this.
