Modern Vespa

So my et4 has just decided to not start. Was fine Wednesday night, wouldn't start Thursday morning.
I have power to my lights and I have changed the spark plug (which was a pain).
Anyone got any ideas for where to look now?
Thanks

What are you experiencing?

Do you hit the starter button and

A) just a click
B) a click and a whirr,but the engine doesn't turn over

Or C) engine turns over fine and strong just not catching?

A quick video uploaded to youtube and linked to here would help

Good luck!

Just a click of the rear headlight when I squeeze the brake lever.

Oh so nothing at all when the starter is pressed after the brake lever is engaged?

Is the rear brake light coming on/tried both brake levers to start?

absolutely nothing.
I'm thinking it could be a dodgy starter switch?
Sorry for the time delay- just had to go and coach a footie game!

Well if your brake lights are not flicking on when you pull the levers your problem is there, as the brake circuit is the fail safe for the starter.

If it does work it would either be your battery, as even a battery that seems fine can sometimes not have enough juice to crank, or like you said the switch itself or something else in series(like a bad relay or connection). Usually if the battery is bad you'll hear some form of click coming from the relay, but that's all.

And no worries, the nights still young!

sorry. Brake light is coming on just nothing from the engine / starter

First thing would be to check the condition of your battery, test how many volts its holding whilst trying to start. Take it you've checked your fuses?

Next would be to pop the head console and try some contact cleaner on the switch. Followed by testing the starter relay.

will look at these when I get home.
Thanks fella.

Gotta be kidding.
So checked battery. Good.
Checked fuses. All good.
Switches good.
I then remember a mate years ago saying sometimes starter motors just need a little tap.
I guess I'm replacing / repairing the starter motor.
How easy is that?
Thanks for the help Knights.

that's an old trick that I have used on cars - but it usually means it's time for a rebuild as tapping will not work every time.
