Now that I look at the part diagram, the wire is terminated with those little slip on flat connectors (not sure the name?) so would probably connect somewhere other than to the battery terminals.
I would think if is connected to the battery it would have power going to the plug. . .
Those are called spade connectors.
The power socket is usually connected to fuse #4; that's the setup on my moto. Get yourself a cheap circuit tester with a 12V light bulb in it.

Yep. I need a new battery for mine then I can test.

Got my voltage tester working and tested the power socket. First I tried to test it by inserting the + probe straight in but it hit the side and shorted out blowing the 15amp fuse. I pulled the connector off the back of the power socket an stuck the + and - probes directly into the white connector. It read 2.5 on the lower scale which calculates to 12.5 volts.
I think I will get the SAE/hella adapter and use the power socket to charge the battery. I can now remove the SAE plug and eyelets that are screwed to the battery terminals.

Just to confirm was that fuse #4 or #5 from the top?

Mid winter update. I did get the SAE/hella adapter and the battery tender junior hooked up back around the end of November. It charged the battery fine reading 12.8v. Put the Stabil in and ran it around the block a few times.
Today, 1/12/20, it was 69 degrees here in the Hudson Valley so a perfect day to get the bike outside (how many from the northeast went out riding today? I saw quite a few bikers around this weekend). It is not registered right now so I just started the bike up and let it run up to temperature, about 20 minutes. The battery was strong and it stared with half choke in just a few seconds. So now it goes back in the garage until the next warm spell then spring in two months!

Got the bike out a few week ago for a start up and it started perfectly. Same today, Friday 3/27/20. Took it for a spin around the block.

Now I want to get some details finished up on the bike before the summer hot weather.
Has anyone had the rear wheel BMW hubcap clip break off? I didn't realize after I took the wheel off last fall that there was a brass metal clip in the hub. The cap wouldn't stay on and then I realized it broke off from the brass clip. I don't see the caps on MAX BMW so looks like I'll have to glue it.
Any ideas?

MAX BMW is good but it isn't the only place to look and if you wait too long, this will be gone.

It doesn't have the BMW logo like the one I have.
I glued the clip back on. We'll see if it holds.

Being the eternal mechanical pessimist, I would assume that the first time you take your bike out you will find the hub missing when you get home.  If it were mine, I would attach the clip with a pop rivet. 

To make a nice job of it, I would countersink the hole so the head of the rivet is flush with the surface, and then hide it behind a roundel like the cage wheels have.

Great idea! You must have been out this spring with all the 50+ days we've had here in NY.

Absolutely!  I put almost three tanks of gas through Ilsa, the red K75 in January and February.  So far in March, all I've been able to do is about another 150 miles for a total of nearly 800 miles since Christmas.  Not a bad winter.  There are snowmobile trails around here that never saw a sled this past winter.

Right. The one I posted is for three-spoke wheels because I didn't check your wheels. What did you use for "glue"?

I used an epoxy. It is very tight and it clipped back on no problem. We'll see when I have to pop it off again.

Sorry, it was actually Gorilla Super Glue in a small tube. I coated the plastic hub cap and then the brass clip and let it sit overnight.

You may not have to pop it off next time.  Heat, vibration, and bumps will probably do it for you.

To be honest I'd follow Gryph's suggestion with a slight variation, rivet with a washer under the head. Then cover the rivet with a BMW car badge of the appropriate size and countersink the back of the badge to accommodate the rivet head. Glue can degrade and let go, and those wheel caps are getting harder to find.

I don't have a rivet gun. It is a cheap design, no? BMW should have had them one hex bolt in the center, screw on, or make them aluminum with little snap on clips around the edge.
Bean counters!

By the way, I bought a new OEM muffler heat shield to replace that rusted one in the photo. $65 new but I think it's worth it.

Everyone should have a rivet gun, I don't know how you have managed to cope in the world without one.  177381You need to rectify this situation immediately.https://www.harborfreight.com/hand-riveter-set-38353.html :superhappy

Dang Martin, you beat me to it.  Unless that riveter is a really shitty knockoff of my Ace Hardware one, it should last at least 10 years.  That's how long I've had mine which looks EXACTLY like it and comes from China too.

In any event, that tool is about 1/4 what a used hub cover is going to cost, and someday your fan is going to crap out and you'll need the riveter to fasten a Spal into the old fan housing.
