I just picked up a nice Batman Forever last night. I played it for a good 4 hours or so and the batwing cannon worked great all of the time. Now all of a sudden it is intermittently working (mostly not working). I checked all plugs and switches and everything looks good. I also checked to make sure the switches are positioned correctly. I don't see anything obviously wrong. I'm not sure what the hell to do here and I looked for a new motor assembly and haven't found anything. Any ideas or tips??? Any help is appreciated. Thanks!

Yes I suppose that would help!

So when a ball gets loaded into the batwing cannon, the DMD displays what is normally displayed, so the game knows that it's time to swing out the cannon....and it doesn't move. About 1 out of 10 times, it will move. I went into the diagnostic menu and the cannon home switch is set, the launcher works, it recognizes when a ball is in it too. It just doesn't power the motor and swing out. I tried to actuate the motor relay via the DMD menu and it doesn't do anything. Is there a relay that I can check for this? What else can I test?

I found the motor online

But i don't know if this is the problem. I was hoping to be able to find a complete motor assembly with the bracket and switch combined. Not sure if it a motor or switch problem. Then again it could be something entirely different.

Bump. Anyone got any ideas?

Yes. Already did that. Switches check out ok.

I also hooked up my meter the the leads that go to the motor for the cannon. I actuated the motor relay via the service menu and it voltage spiked and then I'm pretty sure my either blew a fuse or I fried something....because it didn't spike up after that. I think I'm leaning toward a motor because all switches appear to be ok, and it works some of the time. Maybe a short in the motor somewhere???

Pin_Crazed,

Thanks for the reply. I checked the switch for the cannon registering a ball a bunch of times. It seems to register it every time. I didn't try hitting the + or - in test mode. I was selecting the "RUN" feature, I'll try that when I get home. I just kept restarting the game and loading a ball into the cannon (bat cannon is ready on startup). So it would make my life a hell of a lot easier if the + and - worked to move the motor. Can you check on your BF and see where in the menu that you can move the motor? I think I'm in the right spot. I'm trying to actuate it where it say batwing cannon motor relay.

When I removed the motor assembly to test the "home" switch is when I got confused. There are two tires coming off that switch. I would assume that when you disconnect the cable and you hook up an Ohm meter to the end of the wires and open/close the switch, you should see a change from OPEN to 0 ohms. I did that and there was no change. But if I go directly to the switch points (before the wires) the switch tests ok. It looks like there are 3 leads coming off the switch with only 2 wires. One of the leads has a capacitor looking guy that is soldered to the other lead. Then there is a wire between the two. The one lead between the two outer leads, and one of the leads that has the capacitor soldered to the other one have wires going to the cable connector. So when I measured and the switch tested good, was when I measured across the two pins with the capacitor looking thing in between.....but those aren't the leads that go to the wires...so that makes no sense to me. Is this normal or is that switch bad? In the DIAG/TEST menu, it registers the cannon is at it's home position.

All of the soldering looks to be good. I will try moving the wiring around and seeing if that makes it come back to life. That would be a nice simple fix. Is there any way that I can check power to the motor itself when it is actuated? I think it runs on 50v. That way I could rule out everything else and see if it is just a bad motor. If I disconnect the cable to the cannon motor itself and hook up a meter and then actuate the motor, would that work?

Gotcha. I'll try to do more testing tonight and post any results. This issue is pissing me off! I just got this baby and it kills me that it's acting up! It's a great game though. I like it a lot.

So I started a game and loaded the cannon with the Playfield up. Cannon motor didn't move, so I tapped on it and it started working. Tried this numerous time and it didn't work again. But judging by the fact that it started when I tapped on the motor has to make me thing the motor is shorted....

I have read that one. Found it on a google search. I don't think that is my issue. I inspected the shaft from the motor to the batwing cannon and there is no flat spot on mine.

How do you do the batwing motor test? The only thing I can find is in the coil menu there is a test for the motor relay....is that it? Because the motor NEVER runs when I do that test. I don't hear a relay click or anything.

Ok sounds good. Thanks

Cannon ordered. We will see if it fixes the issue. If not, I'll have a brake new cannon motor for sale! LOL

Yeah. You adjust the linkage. It's a bit of a pain and takes some trial and error. But it is adjustable.

I can't get it to move in the cannon relay test mode. I'll install the new motor when I get it and post ASAP.

I tried that too. I also took off the heat shrink on the wires and checked them for a short. All wiring looks good. I will find out as soon as I put the new motor in though!

So I got the new cannon motor from Bay Area Amusements today (very unhappy with their service and I will post about that later). I installed it in my Batman Forever and it worked for a bit and stopped. I then made a stiff drink and began to dig further. I could hear a relay clicking...hmmmmmmm. Found the relay and tapped it while in test mode and it was sticking! So there you have it. Just a damn sticking relay. Hey, at least I know the motor is good now. Thanks for all the input guys. Now where the hell can I find this relay board?

I'll Pm you tomorrow on the cannon adjustment. Super easy once ya figure it out.

I tried filing the contact and sprayed her down with circuit board cleaner. No dice! Super happy to know what the problem is for sure now.

I do not have the game anymore. But yes it looks like that and is under the playfield.

Glad to hear you got it up and running. Nice work!
