Title: Power Supply Question
Post by: Spidey2222 on June 02, 2017, 02:58:37 pm
I just bought a 421 in 1 Jamma Kit with power supply.  In the manual, it shows a diagram on how to connect it.  The problem is, the manual and the power supply don't match.  It's close but showing 3 grounds instead of the -5V connector.  Also, the wiring harness has a blue, not green, wire but I assume they were just low on green and used blue.  Easy enough.  My question is, can I assume I need to hook the -5V to the first ground pictured below.  It shows the diagram and actual unit side by side.  Thanks in advance.

your question should be dose the board require -5 ? if not you are good to go with that power supply
if it dose then that is the wrong supply
call the dealer you bought it from

I didn't think any of the X-in-1 boards used -5v.   :dunno

If the manual in the picture is for the power supply, ignore the -5v. (they sent you the manual for a different supply)

If the manual in the picture is for the PCB, I suggest contacting the  :censored: vendor that sold you the  :censored:  board with the  :censored: manual and tell them to un- :censored: their products or at least include a correction sheet or note on their  :censored: site.  :bat

(No vendor name or links here please due to Rule 5 (http://arcadecontrols.com/arcade_message_rules.html)  :police: )

Also remember to adjust for the non-standard JAMMA harness wiring -- IIRC two pins on the board (27 and e?) are inputs instead of ground.

Ok, I will contact  :censored: and find out what's up.   The wiring harness colors don't match the manual either.   UGH.

Have you actually taken a multimeter to this power supply?  :bat

Not yet, just unpacked it and was reading through the manual to get a game plan.  I'm a total noob so I am pretty sure I will blow myself up.

I think you are right, in the manual for the board, it doesn't show a -5v so maybe I am ok.

:lol

IIRC the AC wire colors (brown/blue) are standard for UK. (+Europe?)

    AC connections: (U.S. wiring colors)
Ground - FG/Field Ground/Frame Ground (green)
AC 1 - "Active" = Hot (black)
AC 2 - Neutral (white)

    DC connections for board: (look for the divider "key" Pin 7/H)
Connect the (yellow?) wires from JAMMA Pins 6 and F to the 12v terminal on the power supply.

Connect the (red?) wires from JAMMA Pins 3, C, 4, and D to the 5v terminal on the power supply.

Connect the (black?) wires from JAMMA Pins 1, A, 2, B, 28, and f to the ground terminals on the power supply. (IIRC, JAMMA Pins 27 and e are inputs for your board, not tied to ground)

Standard JAMMA pinout.

Most newer equipment just doesn't use the -5 so a lot of power supply makers are saving 50 cents and making the supplies without the +5.
