My Griso's battery charging appears to be slacking.
When new; the voltmeter display on the dash was indicating approximately 14.6 volts while riding.
(Which is within specs according to the manual I Have. A PDF file.)
And when I used all my electric heated gear; the voltage would drop down between 14.2 and 14.0.
(Don't recall the voltage with ignition on but motor not running.)
Now that it's almost three years and 85k miles later.
The voltage is down to around 13.4 while riding.
With electric heated gear; the voltage drops to between 12.9 and 12.7.
And with ignition on but motor not running; the voltage is at 12.9.
(I've confirmed this 12.9 with both the dash's voltmeter and TechnoResearch's Centurion diagnostic tool.)
I changed the alternator belt a few thousand miles ago.
My Griso is a 2010 model that I bought as a left over in Dec. 2011.
I believe the dealer had to charge the battery before they let me test ride it.
And the battery tends to get it's terminals corroded; indicating it's casing may have some hairline cracks near the terminals.
Would it be normal for a Guzzi's alternator to go bad at this stage ?
Can the alternators be rebuilt ?
(I don't see any individual parts; such as brushes; listed any where.)
Or do I simply have a dying battery ?
Thanks;
