Hi can anyone help me i`m not machanically minded but my scoot does`nt always start,
Ive tested the battery and that is fine, could it be the Alternator (starter motor) and if so is it easy to fit or will i need a mechanic?
It some times starts on electric but most times of late it has to be kicked started, Also had to jump off my car a couple of times??

Be careful jump starting off of a car, too many amps while running. Just make sure the vehicle used is turned off. My local Vespa dealer told me this and said that kind of amperage could do damage.

Your Vespa dealer understands fuck-all about electrical first principles then. The car electrics *are the same VOLTAGE* as the bike electrics - the current capability is irrelevant. As long as the connections are directly from battery to battery you'll be fine.

The general consensus is that jump starting with the vehicle not running is a safe bet. The voltage is not the same, a proper running charging system in a car is putting out 13 to 14v. modernvespa.com/forum/topic101346

Fixed that for you - just the same as a bike for heavens sake.

I connected the battery to a multi meter which read 11. Something when ignition was off then read the same when switched on

11 volts is too low. Try to charge the battery, or buy a new one. 12.5-13 volts is good for a fully charged battery. A dip to 11.5 or so while starting is normal. The charging systems on these smaller bikes are not very robust anyway. Invest in a trickle charger for longer battery life. You might be able to find a longer amp/hour battery that will fit in the battery tray. I replaced the standard 9AH battery with a 12AH that still fits the tray on my LX50 (4T)

You have one, if not two, 'shorted' (badly sulphated) cells.

Battery's buggered. It's that time of year...

12.6V at rest.
14.6V maximum when charging.
~13.5-14V in normal running operation.

New battery required. Please, please, give it a gentle full forming (equalising) charge before first use, it should then last at least three years if not more.
