All I get at start up are some solid lights on playfield and head. This along with the ball launch and out lane coils remaining solidly energized.
Weird about the drawings on P29 of the manual. I have violet/yellow going from the ball launch to the outlane kicker, then on to the PPB board. And on P29 it shows a different color wire.I think any brand is fine... looks like Mouser and Digi Key have ST brand... should be fine. Just get TIP36C with no additional letters after the C.
I took a peek at the manual (page 29)... looks to me like the outhole coil is driven by Q46 on the CPU board... and the autolaunch coil is driven by Q23 on the CPU *and* Q1 on the PPB. Wouldn't hurt to check all of the drive transistors on both boards for shorts.
Also... looking at your original post... are you getting signs of CPU life, such as playfield lamps flashing in attract mode, correct graphics on display, etc?
If not, I'd remove all fuses for solenoids and flashers, focus on getting the CPU running first.

Should I be able to gleen anything by starting the game with the PPB unplugged? WIll the CPU board give any trouble/issue indications when powered on without the PPB plugged in?Couple things:
Wire colors sometimes vary from the manual to real life. This is why it's important to understand the functions of the wires.
You've mentioned "outlane kicker" and "ball launch" a couple of times... this is confusing. I'm assuming by "outlane kicker" you mean the outhole... but maybe you mean the laser kick? Best to use the exact terms in the manual.
And finally I will repeat... get your cpu up and running before you continue with the coil issues. Read the guide... you'll probably start by checking your +5v logic supply on the CPU.
Cheers!

will do, thanksI've honestly never tried that... I would just pull the solenoid fuses and leave them out until the game is up and running.
But yeah, the CPU should run without the PPB connected at all.
If the game isn't booting up at all, you need to start with checking the logic power supply (+5vdc). There are test points on the power supply and CPU board.
So I looked over the entire CPU bpard and found all the grounds and test points. WIth the power on but the PPB unplugged I was gettinmg some of the playfield lights and a buzz from the speakers. I got a little over 4v DC out of one test point and a half a volt on the others. But here is a weird thing, I was looking at the board after turning the power off and some of th elined up transiostors on the bard were out of alignment so I just touched one to see if it was loose or anything and it was very hot to the touch and wiggled back and forth. Several wiggled back and forth then once the board cooled down they got solid again. This is awesome to learn but weird.I've honestly never tried that...

Yeah I finally figured out that I had issues with 4 different boards so I sent them in to have them all rebuilt. The CPU, the PPB, the power, and the audio. Now i need to figure out what tools I need to get to re punch down some loose wires on the boards. I think (all new to me) they are IDC?If your CPU isn't booting is there any sign of battery damage? Have you checked your 5V power? That is critical to boot. These Data East machines often have a leaking 5V capacitor that can etch through the traces on the power PCB. I've fixed a bunch of them. It was bad in my Rocky and Bullwinkle. I had to fix traces as well.
