charging issue

[Kiwi_Roy]

You mean the big ground on the right side of the bike just under the seat lock mechanism? Yep that's nice, clean and tight. battery terminals not greased, tight and clean

 

All the fuses are in good shape, just removed the fuse carrier and also the wires under that are clean and not burned.

 

The battery (Odyssey) is working properly as far as I know is still cranking the engine and even after hours of sitting unused still has more than 12.6V

 

I'm getting mad trying to find out how to solve this problem!!

You mean under a gearbox bolt not bolted to the seat release lock, I ask because that's how I found mine under a wimpy screw.

yes, it's a separate bolt, not the seat release box.

Tonight I'm gonna try what you told me, about the difference between the battery and the voltage regulator tensions.

Thanks guys I appreciate your tips!

Ok so... while I was trying to check what you told me I found that now the regulator is working properly, I don't know what to say...

The only thing I did before turn on the bike today was check again the loosen connectors under the fuses, the first two (start counting form the form of the bike were not properly tighten.

 

Before to say I solve the problem I want to try tomorrow again.

 

I stil have the problem of battery light OFF with the dashboard is ON while the motor is not running , of course it turns ON if I connect a wire on the black wire from the regulator and ground it as you told me but if I do that the light remain ON while the engine is running.

And the second problem is the battery light slightly ON while the engine is running at any RPM.those are the symptoms that something is not working properly somewhere inside the Luigi's wiring

 

Any ideas?

Guys I think I found the problem of the battery light, one of the new connector wasn't done properly and the copper inside the wire was barely touching the  end of the connector, replaced the faulty connector now everything seems working properly, the battery light is ON when I turn the key and is completely off when the engine is running!! EUREKA!!

 

The battery now has less than 15v at 3000rpm so I think the problem was a not-completely-tighten connector under the 10 and 5 amps fuses.

 

Thanks to all of you for your tips!!

That's great, Guzzi created another electrician

 

Can you identify the wire on the schematic. I'm curious why we got those symptoms.

 

What Year is your bike?

Does it have an electric petcock or is that fuse left empty?

[passator cortese]

My bike is 2002, "old style" manual petcock (and of course is leaking) 

The wires involved where the white/light blue and black/black out from the regulator but just to make sure I replaced all alternator/regulator connectors.

 

You were probably right, the 17V at the battery was caused by a bad connection causing an increased resistance under the 5 and 10 fuses, this resistance was causing an increased "request of tension" form the regulator to the battery.

 

I hope I'm done with V11 wiring for a long time!!!
