Re: Sinistar restoration help

Drawing set is awesome. Right away I found a connector that was
turned around and after switching that I got the machine to power up.
Going to ship the power supply board to Dokert for repairs because
it's been really hacked. Hoping to pick up a few wire connectors
because one or two that were connected to the power supply board have
been melted or aren't the right size. What would be a good place to
pick those up? The real Bob Roberts? Also, what steps do I need to
take to go from bare wires to connector. Are there little metal tabs
that I crimp onto the wire and then slide down into the connector. Any
help with the proper names for these things would be great.

I just got my drawing set in the mail, so I'm going to dive in and
start checking things.  Thanks for the encouragement and advice.  I'm
sure I'll have more questions along the way, but right now I'm going
to start by making sure the wiring harness is returned to it's
original state (no wires soldered directly to the board) with all of
the proper connectors on it. After that, I'll see what happens.

Thanks again and I'll keep the boards updated on my progress.

I just picked up aSinistarCockpit that I'd like to restore.  It is
complete, but needs some attention.  It has all the boards, but there
has been some wiring cut and a few other wires soldered right to the
power board.

The machine won't turn on, and the transformer block look like it's
seen plenty of water.  The cabinet itself has lots of swelling, so I'm
not surprised.  Boards look very clean and free of corrosion or other
problems.

I'd love some suggestions/help on where to go from here.  If I
installed a modern switching power supply, would I then need the power
board anymore, or just wire all of the things needing 5 or 12 volts
right to it?

Does anyone know where I might find a Williams transformer / power
block to replace mine?  How about aSinistarcockpit wiring harness?
I know that one is asking alot, but I'd be fine with a homemade one
that someone built using the original wire colors.

I'm not an expert at this stuff, but I can solder wires and replace
wiring harness connectors if I can find where to buy them.  Still
figuring out how to use my multi-meter to test things too, but I'd
love to learn.  I'm determined to get thisSinistarcockpit up and
running.

Thanks!

P.S.  I also need to know how to remove the plastic seat from the
cockpit so I can repair it.  All of the "screws" holding it in place
have heads like nails.  Nowhere to fit a screw driver or socket.

You need the original power block in the bottom because it serves as the
isolation transformer for the monitor.

Get in there and start checking voltages. Cabinet interlock switches are
a common cause of a game being dead.

This stuff is surprisingly resilient to water. An old fashioned 60Hz
transformer can look like a rusted block of junk and still work just
fine. Switch contacts, connectors, fuse holders, stuff like that are
prone to corrosion.
