This is where real time be better.  I feel like yelling, as I have to say so much 
to possibly make a little progress.  Not you alls fault, but my lack of how to say 
it all clearly...  It was so easy to call Russ and he would walk me though it, 
with amazing skill and patience.  

So, if the idiots are acting as ground, why then does the indicators still flash 
with ignition in run position?  I am not touching the turn signal switch (even 
eliminated) or the dash lights.  

Let me explain again.  I get in with key in off position, touch only the key,
when turned to run position, the gas gauge, indicators, and idiot lights flash.
No turn signals until the switch is moved to open the right or left circuit or
E.F.S. on; all lamps work properly, checked twice by Gizmo Bob and Jack (thanks 
again!).

Really late, and the dog's snoring is putting me to sleep...


Thank you so very much Bob!
