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 ~
