Looking for some help. First time post so please bear with me.
I recently picked up an Gravitar. Game worked before I hauled it home. When I got it in the basement and examined it with the back off I noticed resistor R100 on the deflection board smoked on power up. The game still worked even with the resistor very crispy but
seemed silly to leave it that way.
My next step was to search the Internet for info. I ran across articles on marvin3m
on how to bullet proof the video with the addition of a Zanen cap kit, additional parts
recommended in the article, and a LV2000 board. The info I am referring to is here:

I also went through some more good writeups on vector operation located here:

http://arcarc.xmission.com/PDF_Monitors/Atari Monitor TM-183 3rd Printing WG 6100 XY Quadrascan .pdf
I then went ahead and purchased the required parts and set about repairing/upgrading
my game. I've gotten to the point where the game is put back together and the spot killer
light is on. I smell a slight electrical aroma (no smoke though). I've triple checked the 6 button chassis transistors are not shorted to ground and they are not. I've opened up my working Space Duel to verify I've plugged all the connectors on to the various boards correctly. Went thru all the components to verify the correct electrical orientation.
For the tests that indicate the monitor should be disconnected does that mean disconnect
all the high voltage cage wiring except the lead going to the tube and disconnect the neck board or something else?
For the tests that indicate the monitor should be powered on how long is it alright to do
so before doing harm to the monitor or other components?
Appreciate any and all help.
