of course we are interested !

The retailer was Impact Battery. The have east coast phone hours, but were easy to reach and very easy to talk to. Knowing that an AGM battery can fail that quickly let's me know that I'm not crazy.

Also, I removed the battery from the bike, when I did, my new (non-RE) terminal broke. To make matters worse, the terminal on my battery tender connection broke too. I will be replacing those along with the battery.

The replacement came in and has been installed. I put it on the battery tender and it took about 10 minutes for it to reach full charge. I had to replace one fuse, but she is now running again.

Hummm...which one?

As many have alluded to AGM batteries can fail catastrophically. I had a tow in of a nearly new, very expensive SUV. I couldn't get it to crank even with our super high output LI-PO jumper. Had to push it in and when tested the machine spat out "bad cell" within minutes, funky stuff here. Don't want to be a hater but i swear our OEM's are EXIDE.

Headlight and everything else connected to it. When I took initial readings from the old battery, they were not constant.

Is this common to have a failing battery cause fuses to blow?  Pardon my ignorance, but I've never heard of this.

A failing battery will not blow fuses in my experience.  What it will do is take out your voltage regulator if you don't catch it quickly. And voltage regulators can cost more than a new battery.

I'm no battery expert and I don't know why it happened, but the battery began putting out random voltage spikes. With a meter connected, I would see the voltage would jump from 10 up to 14, then down to 11, up to 13, down to 10, up to 12, etc. The lack of a constant voltage might explain why the fuses blew. Also, let's not forget that this was an AGM battery, which I have never dealt with before. The old LA battery just got weaker over time and was still usable for a few weeks even after I had to start kick starting the bike. The AGM went bad almost instantly and was totally unusable within a few hours.

I put a $13. HARBOR FREIGHT FLOAT CHARGER on my AGMs every few weeks - for a day.  I don't feel comfortable leaving an electrical appliance plugged in to any gasoline powered vehicle kept indoors.
This proceedure has worked for me.

yeah - loose connection somewhere.

[longstrokeclassic]

+1 for loose connection.
Possibly where the rec/reg plastic connector joins into the main loom.
Check the internal spade connectors are fully home with their tangs extended otherwise one spade will push the other spade out of the block when both halves of the plastic connector block are joined. Engine vibrations will continually make/break the circuit giving sporadic readings and a weak (or no) battery charge.
Tell tale signs would be black arcing discolouration on one or possibly both of the spade tips found when looking down inside the connector block.

So, it appears that the battery may have caused a different issue.

My running lights (headlight, tail light, dash lights) are blowing the fuse when throttle is applied. That is the only fuse that is cutting out. I will be looking at the battery connection again today before I go home, just to make sure that it is properly connected.

[ROVERMAN]

Something in the twist grip or around the t/body linkage shorting a wire i would guess.

[krimp]

Just like tech support on a computer, I'm going to start with the last thing that changed. The battery. It's possible I have a cable shorting out and causing the problem.

Yes, when something is 'broken', always check the last place you 'fixed' something.  Ask me how I know
