Now I'm wondering about the MAX II Byte Blaster II. The LED that is stuck on is driven by the MAX II .. does it have internal FLASH ?

Wrong terminology; the circuit you provided an image of is a "USB-Blaster II".
The Cypress FX2 has internal memory and the MAX II has internal memory. Both of these devices need to be correctly programmed with USB-Blaster II firmware (which is proprietary to Altera).

The attached section of the schematic indicates SCTX is the signal stuck on. ( yellow highlight ). There is a mismatch in the schematic
since the schematic says the associated LED is D9 but the silkscreen on my board says LED D8.
I may have to bring up the .brd file to determine which signal / LED is the actual one stuck on.

SC = SystemConsole, so my guess is that this is the SystemConsole communications interface transmitter LED.

Anyone have any experience with the MAXII Byte Blaster ... is the RTL design available for me to determine why that LED would be stuck
on when I try JTAG operations and the SW4.3 , "factory_load" is not set on ie user mode ? ... does that mean I have some code in
the FLASH for the FPGA + NIOS that is loading on power up and shutting down the opening the JTAG loop or somehow shutting down JTAG
even when I only have the FPGA in the JTAG path . ie all other JTAG devices bypassed ? That us what the factory inferred .
Also , any hints on getting the BTS to work ... ? I thought I could do a visual check on the FLASH contents on the card that is acting up
vs the good Arria V starter kit card.

I'd recommend filing a Service Request and talking with someone at Altera directly.
If you're seeing differences between two Arria V starter kits, then its possible you have damaged one :(
