I checked my battery (3 years old) and it holds 12.6V.
I trickle charged it too but no affect...
I only have usb port accessory installed - nothing extra to increase the load.
Do these vespa's (with digital mileage and clock display) have the renowned clock battery LR43/386 buried in the instrument panel still which could be dying?
What else should i look at? Electrical shorting?
