Hello folks,

Just finishing up a TZ resto and am having two problems that I am looking for insight on.

I just installed a new Ingo clock board and it is acting very funny. On start up it turns very fast in only forward and then tells me that the “clock is broken”. I went into the clock test menu and it doesn’t matter what section I am in on the clock test menu: “The clock is stopped”, “Forward fast”, “Forward Slow”, “Reverse Fast”, “Reverse Slow”, (any of them) the clock is actually moving very fast in the forward position and won’t stop unless I exit the test menu. In the test, it's registering all the optos correctly the hands are passing through as far as I can tell (moves very fast) and showing the correct time. In the solenoid test, "Clock reverse" doesn't do anything but all other solenoids operate normally

I also have a flasher problem:

Flashers not working: (inside ramp, upper right flipper, gumball hi, mid & lo, upper right ramp).

They are all tied into J107-6 but so are "bumpers", "Power payoff", "mini playfield", and "upper left ramp" and they are working fine so I don't think it's that leg. According to the manual the other leg for these flashers is spread across three other connectors, J124-5, J4- 1 through 5 (which has to be wrong because 1 and 3 are empty), and J3-5 (again, has to be wrong because it's empty) so I am skeptical about it being tied to all three (although 2 are on the 8 driver board)

Any help would be appreciated.

Thanks,

Jesse

Thanks for the redirect to the other thread Miguel, it was very insightful. I am starting with the clock before I move onto the flashers....

My motor control board looks fine and I re-flowed everything on it to no avail. I took my Ingo board out and it is still doing it, so I am ruling out the new clock board. I am seriously leaning towards the A-16100 as my flashers that also aren't working are all but one driven off of the aux board. The two symptoms both tying to one board hopefully aren't merely a coincidence.

I of course no longer own my IJ, STTNG, or RS that I could just swap the board out and test. Anyone have any ideas as to what goes out on these aux boards or maybe what I have malfunctioning could point to the possible culprit. If I could replace a few dollars in parts on the board and keep it original, that would definitely be preferred to swapping it out with a new RD board.

Thanks again,

Jesse

It is, I have plugged and unplugged it so many times, I couldn't guarantee it was every time though.

I tested all the TP102's on the aux board and all showed between .4 and .6, same with all the 2N4403 pre-drivers. I also did a continuity check on all the resistors and diodes and none appeared to be open.

When I go into clock test mode and the clock just spins fast in the forward position no matter what test mode it's on, grounding the tab on the Q10 transistor stops the clock. Not sure what that means but I pulled that test from the other thread where it would only run backwards.

Turns out it was the AUX board because I tried a RD replacement board in it and everything works great. Any ideas what would be bad on the board to knock out the upper right flipper, gumball hi, mid & lo, upper right ramp flasher and make the clock go all wonky?

Ideally, I'd like to fix it and get it back in the pin.

Thanks,

Jesse

Thanks guys, I will order a socket and replace the chip. It probably got fried by reversing the ribbon cable accidentally. I will follow up on the resolution once I have swapped it out.
