Im in a deep need of a pdf manual for excalibur(gottlieb).
The flippers suddenly stopped working. I cant find any obvious wrong with them...
I recently changed the mpu for a lisy. And the flippers worked fine. But then I came up with the bright idea of cleaning the playfield and changing the rubbers. After that the flippers wont work.
All fuses are good.
I changed back to my old mpu that is a little unstable. But no change..
If anyone got a pdf manual. It would be nice if you could email me it...

Check the +24v switched fuse (F8, usually 8 amp slow blow for System 80B games) and the 'Q' (game over) relay.

Where is F8? I have a +24v on F4 (8amp) in the bottom of cabinet. And that fuse is good.
Where is Q? There are 3 relays under the playfield. No names on them.. The switches look okay when I move them

Just to clarify... The game boot and plays.
But all 4 flippers are dead.

My bad, the switched 24 volts in Excalibur is indeed F4. I'm not sure which relay is the 'Q' relay in the bank, follow the orange/gray/gray wire from the flippers to the relay bank. The 'Q' relay is driven by lamp 0 (Q1 transistor) on the driver board.

Are the kicking targets working? If they are, you must have a lose +24v switched wire, if not, the 'Q' relay is not being enabled or you have a bad flipper ground. Try reseating (with the power off) the CPU <> Driver board interconnect cable.
