As mentioned in a previous post, you need 23v DC unregulated to trigger the inputs 5v won't do it.. 12v just about does it, but I'm using the proper 23vdc for the inputs...
The schems and wiring diagram are scanned and online, you'll see how it's wired on there, I have it all correct...
I might just end up sending the Pcb back to the owner to try in his cab, but there is no reason this shouldn't be working on the bench the way I have it wired, hence my post...
Sidam also uses this wacky 23v for inputs on Explorer and Missile Storm.. I haven't looked at my Sidam centipede, but I bet that does too, those wacky Italians.
