    Alt.. wiring !! 3G upgrade question ??

    My "66" Mustang
                                             !!!!  Interior lights flickering  !!!!
    Volt meter gauge in dash says  14 V at idle 
     Hand held meter says 14.9 at the battery and at the charging block and 2nd battery in trunk ... no difference from idle to 2,ooo rpm ... 
    Even with full electric load AC turned on headlights turned on all interior lights electric fan on and stereo with C -D changer and Amp .. still reads a good strong 14 volts ..    

             At regulator
     A- terminal cut the yellow wire short ran it from starter solenoid battery terminal pigtail ( yellow  and  black  / yellow stripe) to alternator .. A - terminal      
             At regulator  
    Tied together white F - terminal ( old field )  to green / red stripe S - terminal ( from ignition key)     
             
             At alternator  
    tied white from regulator to the green / red stripe from alternator I - terminal    
             At alternator 
    Looped  S - terminal white / red stripe to  Stator plug on back of alternator      
             At alternator 
    Attach # 6 gauge wire from starter solenoid battery terminal to alternator battery terminal      
             At alternator
    Attach # 10 gauge wire from engine block ground to back of alternator case   

    So what should I be looking for a loose ground or something else in my wireless ??

    Has it ever worked correctly or did this start immediately after converting to 3g?
    Did the interior lights do this with the old style alternator?
    With headlights and AC and interior lights turned on, do the headlights flicker also?

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.
