2011 derbi senda x race brake light issues

Been a while since been on here just bought a 2011 senda 50 for 500 but I'm having brake light issues the pedal or lever don't activate the brake light it's had an led rear light fitted and lights up when running but doesn't get brighter when brakes are pressed any suggestions ????

 

does it work off the front brake switch?

 

No nothing at all front or back going to try and trace a loose or corroded earth wire but if it isn't that I'm stumped lol

 

Just checked my wire from front switch goes into main loom also wire from the rear goes into a connector block that also goes into main loom it's gotta be at the light as both are not working

 

Will do well I won't I'll ask maintenece at work lol

 

Done it found a very coroded block connector cleaned it and I now have brake lights thanks for all your help and was this an ok buy for £500 2011 derbi senda x race

 

one thing to watch out for, the front of the loom where it goes past the steering head tube, can break, ive soldered a lot of them in the past!

 

Also does anybody have any parts for these I'm in need of a new stand and where the best place for tyres if anybodys from the west midlands and I'll look out for it

 

Already fast enough no idea what's been done but will get right up with ease and stay up in 1st and second and I know it's going much faster than my last bike but can't be sure as Speedo cables broken but might crank and 70 kit as well depends how soon I need to rebuild

 

Definatley boring lol don't know if i van register it as a 70 or not as can ride up to a 125 anyway just use this as the insurance is cheap lol I'm going to take head off soon and look at size of piston as have a slight feeling it's already got a 70 kit on it but reckon I could get an indicated 60 out of it as it is

 

the senda makes 7hp on the standard pipe and cylinder.... for parts, you can use derbi senda/ aprilia rx/gelira something or other. all the same shit

 

Looks like I got happy to soon as when the bikes running the lights are backwards bright when running and dimmer when braking so dosent make a difference lol I'll swap some wires round tomorrow and see if that helps
