Hurricane GI Issue

I'm fairly new to the pinball world and have an issue with my Hurricane that I would greatly appreciate some input on. The right side of the GI seems to be stuck on at all times except for attract mode. It will blink occasionally in attract mode. However, when the ball drains and all the GI should go out, it stays on. The other issue is that the start button and coin lights are not working either. I have new LEDs in them so I know the bulbs are good. Could these be related?

I assume it is either Q12 or Q14 that controls the GI but I'm not entirely sure. I uploaded a picture of what it looks like when the ball drains.

I can replace components if need be but still learning so I'm not sure where to look since the lights are on. It's confusing because they will blink in attract mode.

J120 has already had the connector replaced. No other signs of anything burnt related to GI. If that helps at all.

I found that J120 and J121 where switched. I confirmed from the schematics. Both of those connectors had been redone and looks like they were plugged back into the wrong place. However, that didn't seem to fix anything. I did run through tests and found that the white - green connected to J121 control the right side GI that is stuck on. However, it does test as it should when running system tests. I'm also guessing that white-violet that is on connector J120 controls the start button and coin lights as that test didn't have any lights on at all when running the test. Interesting. Any ideas?

Check all the fuses and all tested good. Couldn't see any burnt traces. I attached a couple pictures. I hope that helps some.

Interesting. If I move the violet wire to the correct pin. No lights come on on the right side GI. Move it back to pin 5 and the right side GI stays on but only blinks in attrack mode like before. No effect on coin or start button light. I have left the violet wire in the pin 6 where it should be.

I get nothing when I ground Q12. It does look like Q12 has been replaced before. I did test that my ground out wire was working on the left slingshot. Possible that Q12 is bad? Or what does that mean if ground out Q12 does nothing?

I can happily say that it fixed the start button and coin door lights! But still nothing to the right side of the GI. I did try to short out Q12 but nothing happened! Makes me wonder how much other wiring the previous owner got wrong....

I do not. Here is what mine looks like. What page in the manual shows. J115? I’m understanding how to read that now but can’t seem to find it. Looks like I’ll have to re wire the J115 pin.

No problem! I just now noticed your edit. I’ll bet that is the issue! I’ll work on it tomorrow after I get off work and post the results. It looks like there are a couple wires wrong on my J115.

According to the pinwiki photo...I should be adding a jumper from the 10 pin the 11 pin. Does anybody agree? The markups are what the pinwiki shows.
I did switch pin 4 to be a solid with a jumper to pin 5. I just reversed it. Not sure that matters but figured I would do it so it matches.

That fixed it! The right side GI is now working as it should. The only issue I now have is that the second from the bottom light for the 4 cat's target seems to be staying on when all other lights go out but blinks normal during attract mode. I'll investigate more and report back. Huge help so far though. Thank you! Learning a lot.

Testing ( First in line is the test that was ran, after that is what also was activate)

Juggler 1 | All scores x2 - credit button blinks
Juggler 2 | All scores x3 - credit button blinks
Juggler 3 | All scores x5 - credit button blinks
Juggler 4 | Clock - credit button blinks

Flipper lanes | 1st cat target - credit button blinks
Credit button | 2nd cat target
Left sling | 3rd cat target - credit button blinks
Right sling | 4th cat target - credit button blinks

Seems as though I have an issue with column 7 and 8

All other single lights work. And the cat insert lights work fine on their own.

Genius! Thank you pinballmaniac40! I am happy to say that everything tests 100%. I now have a fully functioning Hurricane. Whoever did the wiring to fix those connectors sure didn’t do a good job. Thank you for being patient and helping me understand how to trouble shoot issues like this. It will greatly help me out in the future.

Looks beautiful!

Now to fix BK2000
