I am very excited to have picked up my first pin today for the right price of $50.00. This guy wanted to unload it, he didn't want to put the time or money into fixing it, he didn't even know what was wrong with it. He just wanted the space free in his garage. It even included the manual and schematics. I've been waiting for a deal like this for a decade to try my hand at fixing one.
As you can see, it is missing the Solenoid Driver Board so i will need to purchase one. I saw a few brand new for $135 and some guaranteed working ones on ebay for around $90-100.
This is my first pin so I am still just beginning to learn. So far I have began by following the very through guide on pinrepair.com.
All the resistances on the coils are testing out good with >2.5ohms.
My voltages on the power board are a little out of spec:
TP1 = 8.0V DC <- high (4.6-6.2V)
TP2 = 199.7V DC <- low (203-257V)
TP3 = 9.9V DC <- low (11-16V)
TP4 = 7.5V AC <- good
TP5 = 45.5V DC <- good
All fuses looked good. I reinforced the ground on between pins 18+19 on J3 on the MPU and jumped it to the board edge where the common ground was as recommended by the guide. I fixed 2 broken pins on the power supply board J2 connector and decided to plug it all in and see what happens.
So far so good, no smoke or blown fuses! The playfield lights up a little bit. The backglass lights up a too. I was expecting this to be completely dead, the guy said it had some sort of power issue. I noticed the wiring is very old and dodgy on the looms, all you have to do is jiggle them and the lights flicker.
Also, the power LED on the MPU did not come on, but like I said I am missing the solenoid driver board too so I am not sure if it should power up without it or not?
I am really enjoying this so far, its very exciting to watch it come back to life. If anyone has any idea on the power issues above with the voltages I am all ears.

. I play mine all the time! Gotta have some love for SH. Besides it one of a few pins that would look good sitting beside the arcade game of the same name!
