main beam not working at all

[qwerty]

Hi all. Just got a 1993 ZXR 400 L with a slight electrical problem. The main beam will not work at all, either from the handlebar switch, or the passing switch. Could it be the relay? if so where is it on the bike. Also the headlights dont work unless the engine is running, is this correct. All the rest of the lighting system is ok. Many thanks in anticipation.

prob just the bulb

And I'd guess it's an non UK model import with NO light switch so the lights come on automaticaly when engine is started
