Hey folks
Corvette again!!!
Not sure if all the faults are related.
I’ve finally turned corvette on for the first time.
Before hand I’d tried all my mechs and boards in a donor machine so I know they were good. I knew I had some switch errors on my playfield which I’m struggling to sort out.
The race track was working fine. Now it seems none of the optos are working.
I also have optos out on the route 66 kick out (switch 57)
Other optos are working so I assume the ten opto board underneath is ok despite having no red led on. (Should it be on?)
I thought I’d try working through pinwiki, shorting the switch rows and columns on the CPU to see if I could get the switch to register, However nothing happens when I do that.
I was getting the check fuse 114 and 115 message to on startup with connections unplugged, which I gather is ok if you have the rows and columns connectors unplugged on the cpu?
Maybe connected, or not…
But if I press the right stand up kickback target (switch 83) it first registers switch 43 skid pad entry before registering 83.
And if push the skid pad standup (switch 82) it first registers trough 2 (switch 32), then ZR1 top entry before registering switch 83 (skid pad standup)
Worthy of note that all the ghosted switches are optos.
I appreciate that’s confusing
so apologies if I have worded it terribly.
Thanks Obi Wan Kenobis, you’re my only hope
