Hi,
I have posted on other thread and PM’d others with similar issue to no avail.

Heres where I’m at:
New Ingo clock board.... leds on board reacting properly.
All game boards gone thru by coin op cauldron
No other issues. All game switches and optos working.
At start up clock does nothing.
In test, all opto boxes indicate closed and clock just runs.
+/- buttons in test make no change.
All ribbon cables checked and rechecked... all connectors checked and rechecked. All board leds on.
Does anyone have any ideas? Another pinsider that had same symptoms indicated that he solved his by disconnecting a connector for a bill taker that was not installed. I dont have that situation. Could really use some ideas.
Thanks

Update....thanks to all who offered help. I have spent the evening going thru your suggestions.

I pulled, wiggled adjusted and checked harness for continuity.... all seems good.

I switched ribbon cable end for end and replaced with one from working game... no help.

Driver wire seems good connection and continuity.

All voltages correct.

I checked transistors on 8 driver board... all seem fine. Q12 is the one associated with clock i believe.

I will have to dig deeper into motor board tomm.... but i think optos and motor are 2 separate issues.

I may not have put this in first post. When in clock test the dmd reads clock stopped... however it is running.

The clock opto board has an led to indicate power.... its on. It also has led lights to indicate the opto is being tripped. They all register when the beam is broken.

In my research people talk about IC’s latching on or such. That is a bit above my pay grade and knowledge.

I am beginning to think it is some board issue.... since i think all the wiring, voltages, connectors etc are checking out. I will look at that motor board tomm.

Any further thoughts?
Thank you all
