Got an email from a friend in need of a Moon Patrol Harness. No problem, I still have a couple left on the shelf. Ahh but wait, he has a switching power supply.

Moon Patrol doesn't have the problems using a switcher that other Williams games have, so I made a switcher mod for him. I am now going to share it with you, as I have no desire to make these for others.

There are many different ways to do this, and this is what I did. First off, let me say... no I didn't hook up the coin door lights or the lockout coils.

Moon Patrol only requires +5vdc and +12vdc for power.
I used a 12 position Molex .093 connector set and U-shaped crimp quick diconnects.

I tapped into 4J3 pin 6, and tied it to GND so that the original linear power supply can be removed if he even has it. Next I tapped 4J2 pin 3 to +12vdc, pins 8, 9, 10, 11 to GND, pins 12, 13, 14, 15 to +5vdc. It is that simple, however the way that I did it allows for the original linear power supply to be installed at a later date without needing to change the harness back. All my friend will have to do is unplug the switcher and connect his original linear power supply.

Awesome Dave! Get ready to be on call this summer when I attempt to completely re-wire a former Joust that was converted to a World Series--> converting to a Multi Williams ;)
 
I would need the complete set-up too if I were to replace my existing harness. My power board is gone. It has a switcher, but the power and ground wires are all cut, soldered together and crimped to the screw terminals. How much would a full harness with the switcher adapter run, if you were feeling up to do another set?

You need to stand by for yet another key chain order from me, my wife said so.

The Moon Patrol harness runs $40 shipped, the switcher mod would probably be another $5 or so.

Awesome. Sold. LMK when and where to send the funds. You can ship it with my 7 pin DK connector.
