Modern Vespa

Hi,
Fuoco 2008.
Last Thursday i've changed both brake levers ( L + R ). Today my bike won't start.
Battery seems OK ( horn + alarm working fine ), but the starter won't work ( no sound at all ).
I think it's the microswitch ( the one that tell the bike that you press the brake ) but i'm not sure.

Any idea will be great. thanks.

Sounds like a reasonable assumption after changing the brake levers.

Easy to check, do the brake lights illuminate?

I will check the light issue.
In case this is the problem, what's the solution?

Thanks

If your brake lights aren't working then the levers may not have sufficient clearance from the switches. Listen to the click when you sqeeze the levers, it should be a crisp noise.

If this is OK then you may have left some wiring disconnected.

Here's what you need to do:

First hop on the bike, leave the tilt lock on, but take off the parking brake. Then let it roll and try each brake individually to see if it is actually stopping. If it isn't, then your problem is in your brake install. I'm about 100% sure this isn't the case as whether your brakes stop the bike or not have nothing to do with starting.

Next, get a small string/bungee and strap each brake, one at a time, so you can walk to the back and see if the rear brakes are illuminated. I'm betting they're not.

The microswitch is not put in, screwed in, or hitting the brake correctly. They break VERY VERY easily, and are just plastic. Luckily, they're very easy to replace and install, takes less than 10 minutes for both.

Here is more to explain what they look like, etc:

Brake Light Switch

Don't forget to check the fuse in the front right foot plate. I think it's the second, a 10amp fuse that controls the brake lights.

That wouldn't stop the bike from starting, just the lights from working.

Sorry, that will TOTALLY stop the bike from starting. If there's no power for the brake lights, there's no power for the starter relay coil.

Ahh so it will. I was thinking there was a separate fuse for each. There is a protection fuse for that one as well in the battery area fuses(20A). I still think you have a microswitch problem, however.

Mate, before you go chasing the tail. Make sure your battery is 100% charged.

Horn alarm etc will still work even though you are running less than 12v. The starter requires more amps.....

Just my 2 pence.

Cheers

I bought a 7.5A fuse and installed it.
I fixed one of the microswitch ( brake lever switch ) and start my Fuoco.
So i will order 2 new switches
