V7 Charging issues / Dead battery -- PLEASE READ

on the 15 I didn't remove the tank. as I recall just slid it back a bit.

yup, you are correct - tank slides back a few inches. Quick note, I found that the spark plug wires need adjusting - I actually wrapped one of my wires as they rub against the bottom of the tank and rubs the paint off. Worth taking a look if you all have the chance.
 
I just thought I would add to this. I had originally posted a pic (somewhere in here) that mine read fine a year back. Right at 14.4. Six months later needed a new battery, Three more months and needed another............WTF............My regulator is not charging at all is what was diagnosed. My shop has my bike. Replacement regulator #1 was reading 15.4. I suggested the one many used from roadstercycle. They said to me have another one on the way. That new one when arrived registered 15.6. I sent them one to install this AM. Like the plug caps, I waited till I had an issue rather than proactively replacing. urgh.
 
Yes, always best to do yourself. However, any issue with leaving this way till I get time?
The connectors SHOULD be weatherproof and sealed. But do you believe that?

I don't see the harm short term, but it would probably be wise to rectify it sooner than later.
 
Yeah....I knew I needed to find time to do myself....just been so busy this spring. He thought was doing a favor due to the cover being so close. :(

I checked my 2015 5 speed for this issue at 72 miles, the highest I was reading even at 3k rpm was very close to 14.4. I will check again around the first service interval to see if the issue pops up.
 
Just picked up my bike from having the VR installed.

Had the mount that @Stradagene kindly put up for us fabricated at a local shop, powder coated black also.
Bought the replacement VR from here
Took it down to the motorbike electronic shop and he fitted it for me.
He told me it was spiking at 16.0v at 3000rpm, now it is sitting around 14.0v.
I am currently on my third battery and just crossed 30,000kms and I am glad nothing more serious has happened so far!

Thanks Todd and the Guzzitech community for helping me sort this issue out!

Just a final follow-up. First photo is the dealers work. The second from the roadstercycle kit and the third courtesy of TonUp and Wisconsin Racer. Thx guys for your help. Finally happy and although the photo isn't great the wires are about 1.5" off the cover.

Harley. Nice job with yours. Liked the look of you painted plate and went the same way.

Well, my wife's VR on her 2014 V7 Special needs to be replaced and did some checking with Jack Flemming on his VR replacement kit (based on a referral in an earlier post here). The kit is for the single phase alternator supposedly used by these bikes and requires minimal wiring changes. He says it only uses two wires to hook up from the OEM harness, and then uses a new harness( in the kit) from the VR that runs directly to the battery. If correct, this would be a much simpler fix wiring wise.

I'd like to confirm our OEM system is a single phase as I reviewed this thread and didn't see a reference to this, but maybe missed it. Also, has anybody here used his kit FH020AA.
 
The FH020AA (made by Shindengen) regulator/rectifier at roadstercycle.com. Shindengen are the main (or so it seems) Japanese rec/reg manufacturers. Their products are top quality. Whichever way you go with an aftermarket r/r, make sure you go straight for a MOSFET type of r/r. I have routinely swapped mine on bikes for quite some years now. I've never had a bike with MOSFET r/r standard, but some Jap bike do come with them. I have a Shindengen FH020AA on the shelf now, ready to go on my V7iii. I have fitted one on my DR650 already.

If you visit roadstercycle.com you'll see that you can buy kits in various stages of completeness. You WILL need new plugs and some wire. I buy their "Complete Mosfet Kit FH020AA DIY crimp or solder kit!". You can make it fit pretty much any bike.

Btw, take their hint: Wire the output from your new r/r directly to your battery (via the supplied cct breaker). Don't use the existing wiring for the output.
