Default Headlamp flash sierra

Wired up my headlights at the weekend and they all work fine apart from the flash.

Am I right in thinking this is a problem with the switch?

Are you using the later style Sierra switched earth column switches?

If so have you got pin 15 of the indicator / dip-main beam switch connected to earth? This is the pin that the main beam relay earths through when flashing the lights.
