I am attempting to r an r the shut off diaphram. There is an electrical attatchment right next to the shut of diaphram (toward the front and I need to remove it so I can get at the inside 10mm bolt and remove and replace the new diaphram. Seems as if that would have to be removed before unscrewing the ALDA.

New Subject: Where should the alda be set, I unscrewed the adjustment by accident and would rather set it now than sneak under there to adjust it with the manifold on...
