V7 Charging issues / Dead battery -- PLEASE READ

Sounds good. I'll check the 0611 error code again at another time to see if cycled out. If the check engine light doesn't come back on then that's a good sign.
 
Every bike I connect to shows 0611, and clearing it doesn't seem to matter.
 
I posted this on WG too but passing along FWIW.

Bob,

We think Guzzi installed that higher switching voltage regulator/rectifier on purpose. They are all like that. All measure same.


There was no way to expand the alternator size because of the wheel and casting positions so they bumped up the voltage of the zener diode gate switch. Yeah, poor substitute but it was cheap!

You can go back to 14.6VDC reg/rec if you want but in our opinion it doesn’t resolve anything really.

But they are NOT all the same. And the new V7s perform in a more universally acceptable fashion (nothing approaching 15v) so maybe Moto Guzzi decided it wasn't so good. That forum is scary.

I know, just letting folks know what my dealer mentioned....also said will depend on age of battery etc for some of the fluctuations noted. Mine actually measured okay and I think I am just going to monitor over time.
 
I spoke to an electrical engineer about charging a 12v battery and the v7 situation.
He is very familiar with12v batteries used in computer UPS battery banks.
A charging voltage of15v+ calls for an immediate replacement of the system VR.
He could not suggest a reason for Guzzi's 15+v spec
I replaced the VR on my bike
 
If there is nothing wrong with the VR's why did my shop replace my VR and then the factory request pictures of the damaged wiring on my bike and the list off all electrical performed on my bike?
 
Im just curious to know, has anyone changed or thinking of changing their VR?
 
Thanks for this post, luckily my 2013 Racer is reading 13.6 at idle and 14.4 at 4k rpm. So I think I'm good for now even though my battery did die after 1 year (and not covered under the 2 year warranty)
 
Ok, looks like my recently purchased 15' V7 is in the clear for now. Just tested at the terminals with a multimeter. 12.5v off, 14.1v at idle, 14.3v at 3,000rpm. I'll be keeping an eye on it from time to time.

Good job for those that searched and found solutions for the issue.
 
Today I checked out my charging system by plugging into my Battery Tender lead on the bike.
I had text book conditions in that at idle it was 13.4-13.8v. At 3,000 and 3,400 it was not over 14.4volt.

I assume this is correct and good.

My dealer said he had not found a single machine with this problem here in Illinois and he has sold some V7's and has more on the floor.
I don't know if they checked mine at PDI as they don't remember. I guess they need a better PDI chart they save in the customer file, right?

So, does anyone have a problem with me checking this in this manner?

I didn't want to dig back into the battery.

I have right at 900 miles now on this little Guzzi and did first service at 700 miles from the dealer.

So far, so good. I love the machine. It's what I expected but better and I can highly recommend this brand to others.

Did you have the battery fully charged with the battery tender when you checked it?
 
I have been riding the bike and my dealer just did first service on it.

I have no idea if fully charged. I do keep it on a Battery Tender but not every night while riding it.

I can put it on the tender for the next couple of days at home and then check on Friday.
I'm running it back to my shop to install my new center stand on Friday and can check then.
I'll let you know.

Ok and my buddy bought his v7 at Rose Farm in Illinois and his vr was reading too high. Was fine first time we checked he checked again and it was high.

Yup that would be me. After about a 40 min. ride I tested again and it was 15.5V. I think it's about a 50/50 fail rate amongst owners. I don't know that keeping a battery on a tender at all times is necessarily a good idea either. I think they are intended to be used mostly for long term storage.
