Tail light not working but brake light works?

Hi,
i have a nrg mc2, the brake lights work, however the tail light doesn't work? I have replaced the bulb etc , does any body know why it wont work? thanks

 

Check the electrical connections from the stator up to the light switch, especially the ones to the regulator/rectifier. The horn, brake lights and starter work of the battery's DC circuit, but the head an tail lights work from an AC circuit from the stator. On a lot of bikes, the large multi-connectors behind the front fairing can work loose.

If the headlight is working, then the tail light filament in the bulb has blown.

 

or you may find that the wire is broken behind the light itself. It passes through a hole in the rear of the frame and easily gets snagged and chopped over time.

 

Hello I've got the same Problem did you find a fix?

 

i had this problem. turns out the bulb needed turning abit as crud or something blocked the connection, give it a twist. worth a try

 

Mine was exactly the same the bulb wasn't in properly after installing it right my bike was fine

 

glad you sorted it a simple thing like that can have you pulling your hair out.

 

Yeah it did mate I had the bike stripped down looking for a fault in the wireing. Nightmare haha.

 

i know the feeling! i couldnt work out what was up with it as everything checked out with the multi meter, and it wouldnt of passed the mot. i didnt know weather to laugh or cry when i finally sussed it

its the first thing i do now when lights play up.
