Another electrical orientated question!

Ive finished re-wiring the lighting loom on my project and connected the battery up to see what works/doesnt.   All works ok apart from an issue with the indicators.  The hazards work fine and so does the right signal but I get a nasty buzzing sound from the relay when I do the left.   What would cause this... my only thought is the power to it is running through another circuit and not leaving a high enough voltage for it.  Jonny? anyone?  Tis 90 spec

I had this and it was down to the indicator stalk

Ah  so I may have arsed it up when I took the column out then..  Shall be trying another stalk then. Cheers again.
