Take your battery off the bike and charge it overnight, using a charger, not a trickle charger. Despite what they say, new batteries are not truly fully charged. They will normally start fine when first installed and be OK after a good long ride, which will fully charge them. Once you've done that, check again.

Did you check the maxi fuse? If that's not it then I would say grounding problem. 12.7 is fully charged so that is not the issue. That maxi fuse should always be removed when changing a battery.

I'd charge her up.
Just the lights etc. can draw the voltage down to zip if there isn't enough charge in the battery. It may still measure 12.7 volts when there is no load on it but unable to maintain the voltage under load. All the electrical theory would confuse me but if it works,it works.

If you want more than guesses, you are going to have to tell us what you are working on.
When you checked voltage, exactly what did you do?

Do you put it in the wrong direction? The newer (least 04 on) have protection built into them for hooking the battery incorrectly. Grbrown is right about replacements charge. However the small maintenance charger will top them off. It just take a good 24+ hours. What mine took. Think the Harley dealers must put them on a charger or something. But for what they charge ($), they should. Some older style car charger without good voltage control are simple too crude to work correctly on small low amp batteries. They peak the voltage and then stop charging.
