Hi !

Here's a summary of all infos regarding the GI of DW I gathered.
Feel free to add some info or corrections.

Every string is powered on 6.8VAC, every bulb is in parallel with a max of 18 bulbs per string.
All fuses are 5A Short Blow.

GI string #1

• Fuse F110
• Transistor Q18
• 18 #555 bulbs on the insert panel, 22AWG plugged on J121-7 WHT-BRN and J121-1 BRN

GI string #2

• Fuse F109
• Transistor Q10
• 14 #555 bulbs on the insert panel, 22AWG plugged on J121-8 WHT-ORG and J121-2 ORG
• 4 #555 bulbs in the topper, 22AWG, J1-1 WHT-ORG from topper board to J1-1 on resistor board and J2-1 WHT-ORG from resistor board to J121-8, J1-3 ORG from topper board to J1-5 on resistor board and J2-4 BLK from resistor board to J118-3

GI string #3

• Fuse F108
• Transistor Q14
• 3 #555 bulbs on the insert panel, 22AWG plugged on J121-9 WHT-YEL and J121-3 YEL
• 10 #44 bulbs on the playfield, 18AWG plugged on J120-9 WHT-YEL and J120-3 YEL

GI string #4

• Fuse F107
• Transistor Q16
• 4 #555 bulbs on the insert panel, 22AWG plugged on J121-10 WHT-YEL and J121-5 YEL
• 13 #44 bulbs on the playfield, 18AWG plugged on J120-10 WHT-YEL and J120-5 YEL

GI string #5

• Fuse F106
• Transistor Q12
• 4 #555 bulbs on the insert panel, 22AWG plugged on J121-11 WHT-VIO and J121-6 VIO
• 12 #44 bulbs on the playfield, 18AWG plugged on J120-11 WHT-VIO and J120-6 VIO
• 1 #555 on the coin door (may vary depending on the coin door), 22AWG plugged on J3-2 WHT-VIO and J3-1 VIO on coin door interface board, linked to driver board by J2-2 to J119-1 WHT-VIO and J2-1 to J119-3 VIO

Here's a map with corresponding wire colors for the playfield (note sometimes 18AWG yellow wire is used to connect near bulbs) :
IMPORTANT : the image is mirrored, so look at it as if it's the playfield top and not the underneath.
The colors match the wire colors on J120.

Here's a similar map for the insert panel (not mirrored this time), with links between bulbs.
The colors match the wire colors on J121.

Hope this will be useful to someone !
