I am trying to use the fireblade switches.
I have after much buggering about found that the light Hi Lo switch is u/s.

Has anyone out there got one please.

PS: I was initially confused as the book shows 2 relays, one for Hi and one for lo. My loom only has Hi relay and appears to use the switch direct for Lo.

This could of course be contributary to failure.

Thanks in anticipation

As stated in the manual (RRS 1995) the fireblade does have two relays - one for Hi and one for Lo. Although if using sierra switches the relays will have to be wired differently for them to operate as the relay's on the sierra I believe have negative switching.
