Resolved > YEA ~

It appears as though some Motor/Switch in the System had gotten Out Of Sync

ie Signals Crossed ~ I just went out and activated the Slider Lock with a Jumper

Batt a few times (with slider open) leaving it in the Locked config', closed the 

slider & now All Locks are back to Normal ~

        A few days ago a Friend & I had been standing @ the sSlider working with

some Camera Gear that was inside & when We were done I discovered that one

of the Keys that I had on a KeyChain hanging out of My right jeans pocket was

Extremely Hot > guessed that I had been holding it up against the Slider Lock

Contact Pins & didn't think any more about it > I have done this in the past &

it has always before gotten My attention by Actuating the Locks on contact, not

sure what was diff' about this time ~ Anyway, I'm suspecting that that is what

caused something in the System to get "Sideways" ~

        Thanks Much for all help ~

       Thanks a bunch for chiming in on this, I was hoping You would as I suspected

You would be able to do exactly what You just did in providing a detailed synop' of

how the system is laid out ~ I'll do some more testing shortly & let You know what

I find ~ 

       Does the fact that the White Wire @ Slider Contact does not ever show 12V, no

matter whether the Fronts are locked or unlocked give You any clues ~
