K1200RS dead electrical

I searched for over an hour without success, so I'll try a post.

I've recently found out that the trickle charger that was on my 98 K1200RS was borrowed, 4 months ago. Of course the battery was dead. So I charged the battery back up with a 2A charger and after 24 hours, it was reading 14v again. But when I turn the key, nothing happens. No sounds, no lights, no dash, no fuel pump prime, no current drain on the battery and the clock LCD dims. I have tried every combination of switch and interlock. I put it in 2nd gear and rolled it forward and back, to make sure the starter wasn't engaged. I've got the schematic, and can tear into it, but would appreciate the wisdom of experience. Where should I start?

Battery??? Can easily read voltage and still be dead. Just after charge would be surface charge, turn the lights on etc....surface charge gone,dead again.

Jumper cables and your car, you'll know pretty quick.

Now the famous question....are you sure there are 2 ground wires attached to that battery?
