Interconnector harnesses.

CPU board installed and all board connectors in place. The two remaining ones connect to the DMD panel.

Backbox wiring all in place. Will install wiring clips and tidy up the looms once all the game features are tested.

Playfield up and resting against the backbox for the first time in a long time. A few connectors to plug in as well.

Next job is installing the transformer and modifying the voltage jumper wiring.

This is the voltage jumper plug that connects to the primary windings of the transformer. Depending on the location of the pins/wiring, it jumpers the winding taps to allow the game to operate at different supply voltages in the various countries. Here in Australia our supply voltage is 240V +/- 5%.

To change the location of the pins and wiring, the pins need to be removed from the housing and relocated as per this diagram.
20200813_140429 (resized).jpg
Removing the pins can be difficult without the proper tool. These are available in various sizes to suit the different type of pins. Makes this job simple and painless.
20200813_135802 (resized).jpg
Insert like this and whilst holding the plastic housing, push the tool into housing and the pin will pop out.

Both jumper wires removed from the housing.
20200813_135938 (resized).jpg
Once removed, if the wire jumper is to be reused the small ears or locking strips of the pin need to be bent outward to allow the pin to lock into the housing once re-inserted. The ears are bent on the left pin. Parallel with the pin/pushed in on the right pin, this is what the pin extraction tool does to allow the pin to be removed.
20200813_140143 (resized).jpg
One jumper inserted as per the diargram above and it's now ready to connect to the transformer wiring loom.

New set of ribbon cables from GPE. Unfortunately, by the time I got this game the originals were long gone with most of the boards.

Installed and getting a little excited about flicking the switch for the first time!

The flipper opto boards had also been scavenged and a new set including actuators were required. They are installed ready for action.

It lives!! Playfield GI LED's are all lit. Looks great, very happy to see it lit up like this.

Without the coindoor connected the display shows the standard information with a few columns out by the look of it. The display was as-is when I received the game, with no idea if it worked at all.

What happened next was quite unexpected. A viloent shorting noise brought my attention to the backbox with the lamp insert door open, only to see a small shower of sparks coming from the sound board, a loud pop and a small drift of smoke coming from beside the heatsink. All that happened before I reacted and turned the game off. Somewhat deflated and thinking I'd done something stupid, I began to investigate.

With the sound board removed, eventually I noticed that C46, a 1uf Tantalum capacitor had shorted. If you look closely, down between the 2 larger black capacitors you can see the aftermath.

Here's a closeup picture.

Sometime in the past I'd read accounts from others here on Pinside describing this happening, but never experienced it myself. Quite concerning and smelly.

Whilst waiting for some replacement capacitors to arrive. I decided to removed the sound board and replaced it with one from another game, swapping the ROM's into the replacement board.

This time there were no fireworks, thank goodness. With the coindoor temporarily wedged into the cabinet opening and plugged into the coindoor interface board, I could use the buttons to get the game into attact mode and see the feature lamps alternate. YES!! A real sense of achievement now.
