Hidden hack of the day

[viperrwk]

I hate these hacks that hide in plain sight. No wonder why F107 kept
blowing.

Oooo, that one's nasty. It'd take me a while to find that one, too! Maybe somebody
on the line was color blind? :)

Unlikely as for the most part wiring loom folks tend to be women. Plus
if it was a factory error one would think they would notice F107 being
blown...

As for some of us who ARE slightly colour blind (I'm red/green
deficient), what is the problem in the picture? I'd troubleshoot by
unplugging the connectors to see if the fuse blew when subsequently
powered up, and if not - then holding the connector on an angle while
plugging on to see if there was a small spark (cheating, but finds these
sort of things fast, and you can always replace the pins). If you want
to be clever put a low value resistor (10 or so ohms @ 25 to 50W) in
place of the fuse to reduce the spark.

From the discussion it sounds like the connector is mis-pinned.

Hack? meh...

It appears both GI connectors are mispinned.

If there's something else, I'm missing it, too :)

I was waiting on a Hint or 2 myself ! .

[viperrwk]

Give Korn BIG props for seeing the swapped wires on pins 10-11 on J121.
As far as I can tell that's a factory job.

The other thing wrong in the pic is J120 - the white/yellow wire should
be on pin 9, not pin 10 so it's piggybacking on the return. The wire
looked like someone reinserted it there after it had been inserted once
already. Perhaps done at the factory, perhaps not.

John's suggestions are good ones - the problem though is that in this
config it wouldn't blow the fuse right away. I replaced the fuse, ran
the diagnostics on the GI, all was good. Walk away and come back 30 min
later - no lights. Fuse finally would burn out (yes used the correct
fuse - 5A SB.) It was especially frustrating because I ran it for half a
day with only J120 hooked up and then another half day with only J121
hooked up in attract mode and the fuse never blew. When nothing is
burned and everything looks ok at first glance, these sorts of problems
can make you pull what little hair you have left out.

Sorry Cody that it doesn't live up to your hack of the day standards!

OK, so maybe I can learn something here. Why does that make a fuse blow?
As far as I can tell from the schematics, J120 pins 1,2,3,5,6 are all GI
drivers and should be interchangeable. Although test may be wrong if it
lights them individually. Also, pins 7,8,9,10,11 all return through their
own fuse to the same 6.8V AC power supply wire. In my mind they should all
be interchangeable too.

This is a WPC-89 right? What am I missing?

So could MacGyver fix this with a gum wrapper on the fuse?

+1 not a hack, a mistake yes. A functional hack would have been better
than this mistake - easier to find and less hair on the floor

Yes - WPC-89.
Everything you say is correct. The problem was that with the
white-yellow wire on pin 10 instead of 9, two GI strings were being run
through one 5A return fuse (this is a PZ BTW.) There was just enough
load on the circuit that it would eventually blow the fuse after about
30 min or so taking out both the right side playfield and top half
insert lights (that was the first clue something wasn't right.)

Moved the white-yellow wire to pin 9, machine was on all day, no
problems.

You guys are super sharp!

I'm pretty sure I'm just being dense here and I'll take a closer look, but
as long as wires aren't doubled up on pins 1-6, each GI string will still
have it's own fuse, just a different one than originally designed for. Are
all the GI fuses the same 5A? If some are lower (i.e. fuse specific to the
load), then I can see how having the wrong GI string would matter.

No real matter here and I'm glad you got it working.... just curious.

Yes, all the GI fuses are the same (5ASB.) Pictures always help me.
