Teenage Mutant Ninja Turtles
Data East, 1991Hi
My turtles has a issue with the GI. Only half of it is working and I'm clueless of where to continue searching now.
I checked everywhere for a loose wire, or a connector that wasn't plugged in, but can't seem to find one.
I even changed the relay RY1, (after tip from a friend) and checked the test points over there and everything seems to be fine.
Are there anybody with a clue of where I can look next?
The circles are where the GI doesn't work, so top portion and left.
On my de checkpoint, some gi was out and in the Colum one of the wires for a switch was broke.
Trace your two wires from the last light back to the head. Check to make sure there are no breaks. Check your Colum/row guide for lights and verify each one on those strings
Have you checked if any of the connections are burned a little? My guess is that you have one of the issues described here:
