hi there guys i have an el falcon that is duel fuel and currently i am having an issue with the lpg. when i switch from fuel to gas it runs great then all of a sudden it starts clicking eratically from the solenoids any ideas why this is happenning. while this happens it is trying to change from gas to petrol while it is clicking. any ideas.?????

have you tested the switch?
because of the constant flicking from gas to petrol can do the switch in.
