So, I have an odd issue that is driving me nuts... My Sorcerer quit on me some time ago, and I took it down to start diagnosis. I pulled the batteries and did not get a chance to get back to it for quite a while. A friend of mine who knows his way around electronics asked to take a look at it, and I said be my guest. He did not get it going and I am not sure what all he did.
Anyway, I cracked into it a few weeks ago, and from a gi only state, added NVRAM which put it into attract mode with no displays. 100+ v was low and 100- was non exsistant. Swapped a known ps in and got the display back, all voltages test good. Game goes into attract, sound works fine, flasher works correctly, displays read correctly, Starts a game, spits out the ball (only solenoid that works during game play), but all other solenoids are dead! As well as nothing scoring at all, no matter what switch you hit! Funny thing though, when I put it into test / diagnostic mode, all the solenoids (Flippers, pops, slings, etc...) work just fine. ??????
Am I missing something really stupid that I should be embarrassed about? When game is started and in gameplay, I tested voltages at the coils and they are there, but they do not fire when switches are engaged, but engage just fine and fire off in diagnostic mode, as soon as you hit the button inside the coin door and put it into test mode you can fire all solenoid just fine!!!??? What am I missing?
