There were still a couple solenoids not firing right. This got the issue much more stable, but still not 100% reliable. I repinned pins 1-4 and pin 10 of J4 on the MPU with new trifurcon.

I completely repinned connector J4 on the solenoid driver with a new female connector and trifurcn. These are the lines that communicate from the MPU to the solenoid driver which solenoids to fire. A lot of times this has correlation to pins 1-4 on J4 of the MPU and pins 3-7 on J4 of the solenoid driver board. The other half of the time, the solenoids weren’t firing in the right order or the right solenoid. I insulated the ground braid and dropped in a new 20 amp fast blow fuse which took care of this issue.Īt this point, the game would boot but only work correctly about half the time. Turns out that the ground braid was taunt and when the playfield was in game flat, the braid was shorting to one of the back GI sockets. Immediately upon boot up, the game was blowing the 20 amp GI fuse. I pulled these and reflowed the header pin joints and that cleaned up those issues on the displays. The game was also having some flickering and flaky display issues on the first and fourth player. to I have a Bally Kiss pinball machine that has been working perfectly for the past few years. A lot of the joints on these were cold, as well as a good deal of the header joints.
This game also had a few chips replaced and socketed on it. Replaced capacitor C23 with a new 15,000 uf 25 volt cap, ran a jumper from the negative end of C23 to ground and tied TP1 and TP3 together. It appears a game starts, no ball is kicked out, but it immediately ends the ball (ball 1). It stopped working but all the lights come on. On the solenoid driver board, I did my usual upgrades. Ive been slowly restoring my Evel Knievel Pinball machine. Hi, I need some help with an issue with my Evel Knievel machine. there's your answer, jumper your board per the 2x2716 instructions instead of the 2x2732 instructions.Working and replaced MPU with a spare and new ROMs No idea what the other board you have had working is jumpered for is it 2732's or 2716's? If it's 2716's.

Did you come roaring in knowing how to fix everything in a game? Of course not. I don't know why people are afraid of doing things with eproms. Heres a video of the wiring harness reinstalled after replacing every lamp socket and. You could verify this with a $35 eprom programmer easily.

It really depends on what those 2732's you have are - are they a duplicate copy burned into each half of the 2732? (Which should work in theory) Or is it a full copy $1000-$1FFF in each (which will definitely NOT work) Electronic performance Action styling 3 Ways to score specials double specials possible. This game has a new playfield installed and the cabinet is touched really nice. Likely the board would work jumpered for 2x2716. The Evel Knievel pinball machine was designed by Gary Gayton and released by Bally Manufacturing Corporation in July of 1976. Original board jumpers for 9316 address space: (Ignore what the numbers mean, just see that they match/don't match) I have found numerous head banging issues like a solder splash causing a short by really looking close at every square inch of the board under bright light. Machine pin sockets have been known to be wide enough to touch a trace between pins with the solder mask pealed back. In total, 756 pinballs and video games were sold over the three days of the first auction 130 on Friday, 298 on Saturday. Viewing began at midday yesterday, Friday 10th September, with the first lot a The Amazing Spider-Man pinball auctioned at 3pm, reaching a hammer price of 3,500. Specially like at the ROMs where a trace passed between two legs. Some of the hundreds of pinballs at the Museum. Check for shorts of two signals together. Running 2732s on a -17 takes some cuts and jumps, make sure you got it right and the long jump between u2 and u9 the wire is not impaled on any sharp post.Ĭheck continuity Address and Data from CPU down to other chips with DMM on continuity mode or your probe into the chip socket while powered up with only u9 plugged in.
In addition to the ones you listed, pin 3, 5, 36, and 37 also have pulse activity.Īlso, I don't know how to interpret this: All the pins showed steady pulse and steady level (probe green LED), but pins 22 thru 26 showed a quickly flickering level (probe green LED) instead of a steady (non flickering) level. Most types of pinball machines have two types of input switches: direct and matrix. For what it's worth, I checked all the pins on U9. general for sale 1 : EVEL KNIEVEL got his new Red.
