Just to make sure no rock is unturned .... did you turn the Guidematic control to the "off" position?  To turn off rotate the sensitivity control knob (Fig 12-99 in shop manual) all the way to the left to the Off position. The dimmer switch should then operate as a manual switch. This might sound like a silly question but have hear at least 2 occasions over the years where the owner was simply not turning the switch far enough to the left to the off position which opens a circuit to the guidematic system.

I think you have to use the same type dimmer switch. That is if you have guidematic, you need to use the guidematic switch with side connector or bypass everything.  If you need one, I have Very Good used ones for $5 + s/h. Shoot me an email to [e-mail]
