Repair logs for pins
Neil Bradley
games. I'm one of the owners of Ground Kontrol, an arcade in the
Portland, OR, USA area:
We have about 20 pins or so, and the logs I've posted below are directly
out of our repair list.
Please keep the following in mind when reading these mssages:
* The pins mentioned are running 12+ hours per day, roughly 345 days a year.
* The logs span a time table of roughly 2+ years
* CNB/Neil = Me. GK=Ground Kontrol.
* Take anything you read in them as advice at your own risk. The
troubleshooting and repair experience of each person varies wildly.
* Discussion is frank in this log. Don't take offense if something irks
you. Remember these are private logs between employees and owners and
weren't ever meant for public eyes, so it's more "raw" than you might
expect.
* The signal/noise ratio is either high or low depending upon what
you're looking for in this list.
* I am not looking for commentary, discussion, critique, or private
discussion on repairs. If you have questions about a specific incident,
post it to RGP and I'll do my best to answer. Let's have everyone benefit.
* I am posting it in the public domain. Feel free to do with it what you
please.
Hope you find it useful.

> (where I was seeing .6V on all but the knocker's line) is the return line. The
> IC pulls those lines low for a second to fire the coil, and when I took a logic
> probe to it, it was working fine. So then I started tracing the power line
> common to all those coils, which went to the knocker first (aha!), and then

> severed way, way back in the body of the machine. I spliced it back together,
> and the coils came back to life. It looks like the drop target mechanism under
> the Terminator head pinched the wire off. We'll need a long term workaround for
> that, but for now its fine."
