Quoted from newmanoconnor:It’s not fuses for the solenoids. But it would be nice if someone could point me in the direction of the right transistors, I’m not the best with schematics.
Page 29 of the manual lists the driver transistors for each solenoid and flasher.
Quoted from volkdrive:Yes, that will get us going for sure. It’s the first machine a buddy from work bought and the pops are dead so we will be starting with the drive trans on board and go from there. Just want to have a good reference so we can get it up and running. Thanks again
The spoon switch has a 22uF capacitor and a 100ohm resistor out of view in the pictures above.
I've found this a useful reference in the past: http://pinwiki.com/wiki/index.php?title=Williams_System_9_-_11#Special_solenoid_problems
Quoted from bowtech:I understand the switch concept but when I press the advance button it only advances to the first test which is the music test and will not advance to any other audit or test modes.
The auto/manual up/down button is a bit weird because it does more than one thing.
Auto/up is when the button is not clicked in, manual/down is when the button is clicked in
From attract mode, if you press advance, the auto/up/manual/down button selects what mode to go in to:
- auto/up will go to audits and adjustments
- manual/down will go to diag test
In audits and adjustments when you press advance with:
- it set to up will go to the next audit or adjustment
- it set to down will go to the previous audit of adjustment
- start button changes the adjustment
- you exit by advancing UP past the end of the adjustments. Going down past the start just loops to the end.
In diag test:
- press adv to move to the next test - you cannot move to another test unless the middle button is in auto/up/unclicked as you cannot go backwards (down) through the tests
- press manual/down to start repeatedly testing something. eg in the coil test, if you activate manual/down, the currently tested coil will repeatedly fire until auto/up is pressed.
- Start button steps through some tests (like lamps). If you advance through all the tests you will get to audits and adjustments mode as above.
As an example, say I want to set free play:
- In attract mode I put the middle button in the auto/up (unclicked) position.
- advance will enter audits and adjustments
- advance repeatedly to get to the adjustment I want to change
- If I go past it, manual/down and then adv to go backwards to the adjustment I want
- start to change the value
- auto/up position and then advance through all the remaining adjustments
- game should boot back to attract mode
Another example, I want to test a single bulb in the lamp test:
- In attract mode, I put the middle button in manual/down clicked in position
- advance
- auto/up
- adv to the relevant test
- start button a lot to walk through the bulbs
- adv to get to audit and adjustment mode
Quickest way out of audits and adjustments from the first one is to jump to the end then go up once.
- manual/down (clicked)
- adv to get to the last adjustment
- auto/up (unclicked)
- adv to return to attract mode
Clear as mud, no?
Quoted from jmountjoy111:That’s the long versions for sure lol. To summarize...
Click the middle button once and then re-enter the menu.
Yeah, that one got away from me... Type type type... post... shit it's a book. 
Quoted from TicTacSeth:I just did my first crimp job on an idc connector. Got a deal on the crimp tool and then got the courage learn to do this from now on. The connector that runs half of the back box lighting was burned. Easier than I thought it would be, don’t know what I was afraid of??? Haha
I also fixed my Pinbot drop targets ... optos just needed to be cleaned. Phew
I’m looking at the schematics, which connector controls the GI for the sling on the right side?
The only way I know to check which string controls which bulb is to peek under the playfield and look at the wires on the socket.
Those wires come back up to the lower right side of the interconnect board. From memory Playfield GI is printed on the board.
Quoted from TicTacSeth:Man, you did it again ajfclark, following the wires I got to the transformer(?) board on the bottom right side under the playfield. There were some cracked solder joints on the connector down there. Reflowed solder (pumped I know what it means and how to do that now haha) and boom! All lights working! So much more light! The right sling was out, the lighting under the blue dividers by the C-A-B were out along with the under ramp lights. Instantly fixed!
I should take a picture of my plastics on the slings, I’m noticing everyone else has blue triangles. Mine probably came from another game, yet I kind of like them!
You mean a relay board? Yes, those things seem to have a habit of cracking their solder joints. eg. check the pads of the relay itself in the middle of the board:

Quoted from Kawydud:I believe Q1-Q4 are for the displays, but I am not certain, just going from this drawing of the aux board since those transistors are not shown as solenoid drivers.[quoted image]
That's the schematic for the power supply, not the aux driver... The aux driver board schematic looks like this:

Quoted from Jerrybest:What does this number on my playfield mean number 10?[quoted image]
It's the serial number of the playfield. First three digits are the model number (553 for taxi) and then the rest is the serial. I think X indicates it's a prototype. If there was an 'I' would be an International/exported game (Europe, Australia, etc),
See https://www.ipsnd.net/View.aspx?id=2505 for pictures of other Taxi serials.
Quoted from MANTO1975:Haha, we have a comedian, I realize that but neither of my other system 11 machines have apron cards.
6" x 3.25" or 152mm x 83mm. For my Space Station, I yoinked this art from the owner's thread, got them printed 6"x4" at Harvey Norman and trimmed the black border off the bottom.

Looks good. Fits well.
