No Display ???

Hello again everyone,

I have been building my Takky for the last few months, using a fully functional 6500's Gazelle. I'm at the completion stage.
VGA mod., Connectors and wiring harness (included 3.3v Reg.)= done.

Firstly: I built the harness and Connectors as per http://homepage2.nifty.com/frogeye/connector.html
(page 3 of 5)where the mounting of 630 Conn. to Analog-Conn.
*added jumper*
Monitor ID input 2 and input 1: *added jumper* from S19 to S20
Monitor ID input 0: I left S21 open (nothing connected to Analog Connector's P20, 24, 25) as the instruction said.

I tried to boot up for the first time yesterday. Booting sequence seemed normal, except there is "No Display". I waited for a while, even hear the computer talks (saying my clock is incorrect)... still no display and no signs of burns or smell from any circuits.

Secondly: I removed the jumper at S19 to S20 to installed Analog-Conn. P20 to S19, P24 to S20, P25 to S21

changed batteries and retried booting sequence several times. Still the same issue "No Display" but I can hear HDD working and computer is talking.

Could some one please help guide me through this wiring steps again? I'm really confuse on this...
Is the instruction meant to install the jumper @ S19&S20, also connect the Analog Conn. P20 to S19, P24 to S20 , P25 to S21 ???

Hoping to hear from you soon, Thanks !!!
