scottyb,

Thanks for the quick post. Yes it was the fuse in the yellow inline holder. I didn't do exactly the OBC bypass test you describe. I did essentially replace the blown fuse with a wire but didn't put the other end of the jumper to the low end of the battery stack and it charges fine, but does turn on the relay as soon as the charger is plugged in to the cart. Will surely give that bypass test a try at my next chance. Do you have any suggested OBC sources? Internet search shows prices between 200 and 240 generally. It looks like I will want to pull the old one to confirm the part number before buying a replacement. The OBC was replaced a few years back. Do they fail often? Thanks again.
