Its the Welsh English again it is like this

A/t the middle position ... = no light
In hold = green light
In power = no light
Switch tested using multimeter on continuity
Switch is connected correctly
I also checked the Wiring for continuity
The orange light for power has been checked for operation and illuminates if tested on the bench using a power source not when its connected to the trol wiring loom
Apologies for being un clear
Joe
