Hi,
A long time reader, first time poster.
I got my Tenere just over a year ago after searching for the right one for me.

It has lots of mods including Full Akrapovic exhaust, stage 3 power commander.
Heated grips, 12v socket etc.
I suspect the headlights were somehow upgraded too, but don't know for sure.

The problem I had was after a few weeks I noticed if I made a hard right turn the main headlight beam would turn off, but all I had to do was switch the full beam on then off again and the main beam would work (until I turn right again)
Then after that the main beam started to work less and less.

I didn't worry about it too much as I only ride in the day time, but last week I put it in for it's MOT thinking he can sort it at the same time, but after 4 days of working on it he called me and said he can't fix it, he's tried all sorts.
(something about it being DC and not AC and also It's a xenon system?) <---this confused me.

He thought it might be the Relay at 1st but after swapping them they seem ok, so it can't be that.
I'm not clued up on electrics at all so no chance of me fixing it.
He said that the lights show signs of life when the bike is just starting, but while running there's no power going to the main beam.

Has anybody any ideas?

I would really appreciate it.

Thanks in advance
