Ok I got my cocktail here, the board isnt in it , but I have a game board. The card edge connector isnt marked pin# 1 etc nor is it made to fit only one way. How do I know which way to coonnect it?

Try to check with the game manual. Check where is the power inside the connector with dmm. Hope this help.

Unfortunately there was no manual....

What's the game board?  Is the cab / board JAMMA?

Doug

JAMMA? ok i think i forgot to mention i'm new with the vids so treat me as stupid ok? The board is a Vigilante game , theres two boards together mounted piggyback . The cabinet has a connector that is oo small for the board so it looks as if somebody created a jumper to convert to the larger size that appars to fit many other boards. Ill try to post a pic..

Bri, Vigilante is Jamma

Ignore the bottom part of this image, somewhere on your board you will see an edge connector like the one shown...
It may or may not have a space on your PCB....anyway looking at it0  the far right is the "power section" just following the right side of your harness to the power supply... the other end will be going to the control panel...

Follow me? holding your harness look at each end one end will have wires going to your power supply that is the end that goes on the right side of that edge connector looking at ifrom the top (top is the side with chips and cap etc...

Sounds like you've got a pre-jamma cab that has some sort of conversion harness added, and your board is jamma.

Here's the standard JAMMA pinout.  All you need to do it locate the end of the connector with the grounds and 5V lines on the end as that is the end that goes towards the notch on the PCB.

But before you plug the board in and flip the switch I'd bust out the DMM and test the voltages on the connector.  You never know what was done with that conversion harness.

Cool thanks, It looks like a home made harness . Is there a harness available to buy , I will post a pic in a few minutes....

$10 bucks I can you a new one with your board
easy peasy I would actually recomend that anyway...
prolly need one for your board too in the cocktail.. just a thought

Sounds fine B1 can you get me  the board and 2 connectors. I think my son might have toasted the Vigilante though, he went and plugged it in and turned the unit on. Please tell me it wont fry the board too easily......

Looking at picture 1

the harness has a green wire at the RIGHT end (as pictured) I "suspect" the is a gorund and the power end I was talking about...

Now still looking at pic 1 the way it sits...the green end would got to the LEFT end of the edge connector on the board

So esentailly flip the harness and plug it in BUT

As menace said turn the machine on WITHOUT plugging the board in and check the harness voltages usng the pinout Doug linked I would start at the grren end and work in...

Always better safe than sorry

Hope that helps
