X relief relay - which one is it?

[diggerbucket]

Folks,

I think I have a problem with the x relief relay on my LCR - question is which relay is it, has anyone got a diagram or picture?

Problem is I am losing power intermittently to some major auxiliaries, wipers, headights, indicators, heater blower.

Could do with some help here if anyone knows

Position 2 on the relay plate - top row, second from the left. Relay type 100.
