Quoted from pinlink:Hoping I don't have to replace that entire front ramp entrances for both ramps. looks hard to find and over $100 a piece. Just for two lights...yikes
For your Ultra Ramps issue, I think you are looking for a complicated fix for a simple problem. Let's start over from the beginning...
Start with the tests... Go into the Test menu, to T.8 Single lamp test. Got to light 56 (location 78). Are your lamps flashing? I am assuming that they will not, but this is a good starting place.
My best guess is that you have a broken wire on the way to your lamps.
Again, these lights are on the lamp matrix in column 7, row 8. So, use the tests to determine if anything else in column 7 is out. Then, look at everything else in row 8. If anything else is out, then your problem is further up stream.
So, column 7 is the Green wire with the Violet stripe, and row 8 is the White wire with the Grey stripe. Begin tracing the green wire first, from where it connects to the boards (molex connector) to it's source, which is going to be another light named in that same row. You should also trace the Grey wire, which will lead to another lamp named in that same column.
Odds are that you simply have a broken wire, far from the billboards where the problem is showing. This theory is inforced by the fact that BOTH ramp lights are out. One of the ramp lights is fed off the other, and in turn, both are fed from 2 other lamps (green/violet and white/grey).
I don't know the exact path of the wires, or I would tell you specifically where to look... But you should be able to find the problem in a few minutes.
Just as an example... I myself had an issue with one of the opto sensors in the ball hopper. At first I was thinking the problem was the opto or the sensor, then I thought it was the opto controller (by the left flipper), but as it turned out, all I had to do was look at the matrix and run the switch tests. All that was wrong was a broken wire on the left striker target, between the spinner and left ramp. Again, the problem was FAR from where I thought it was. Use your lamp matrix map, and tests in T.8, and then trace the colored wires.
