Darren something is wrong with the bike. Those 750's are notorious for stator and regulator/rectifier failures. One of those is bad. Post down in the 750 section and they can walk you through testing those components. The 'basic' test though, is to put a multi-meter on the battery and run the bike at about 2500 rpms. You should be up close to or over 13 volts.
Also, it's still possible you've got a bad battery. Every time a lead acid battery (and AGM batteries are still lead acid) drops below 12.4v, sulphate crystals form on the plates and eventually, this will impede it's ability to hold a charge. So once you determine what components have failed, you will want to load test the battery. This can be done on the bike, or it can be taken to a dealer or auto parts store and they can hook it up to machine that will load test it.
Also, jumping a bike is not the best solution. In a pinch? Sure, I'd jump a bike before I walked home too! But it's not something you should rely on. It stresses electrical components, and Kawasaki recommends NOT jumping. On a dual stator Nomad? Not necessarily the case. But on the notoriously limited 750, absolutely.
Fantastic bikes! Just gotta figure out what's going on with the electrical system and you'll enjoy it for many many miles.
By the way welcome! I hope you and your family where not impacted too badly by the storm.
