Space gun and solenoids...

All interesting information, as the recoil in my Space Gun is the last thing I need to fix. So the pots actually control the recoil function from the board? For some reason I thought there was a separate smaller board that controlled this, but that sounds incorrect. And finding a Space Gun manual is tough these days.

I will try to clean, and not grease, the plungers and sleeves and see how that works.

And I heard that Operation Thunderbolt recoil solenoids are the same part as in Space Gun, but I am not sure about other Taito games. Can anyone else confirm?
 
Operation Wolf 3 have the same guns and inside look the same,but I don't know how they are controll.
I think on Space Gun,the control is trough the both transistors from the board,because at the pinball machines the coils work trough the transistors.
But I doubt it's problem from them,because if the transistor fail,the coil will not work completely or it will lock immediately,and not to be weak than the other.
The pots are just or the movement of x and y axes.
Never grease the coil or plunger.This is wrong.You can grease only if you have gears.
I think there not have full manual with schematic for this game,I searching for this from years.

Thanks Arakissun. Good info. I agree that finding the full manual for Space Gun is impossible. And I was hoping Operation Wolf also used similar parts, as those guns and parts are readily available. Operation Wolf 3 is very rare, and finding parts from that game will also be tough.

I guess it's back to cleaning the plunger and checking the board for me.
 
Can you make some video with both guns in action without the plastic to exactly the difference?
Also both assy are with same parts-springs and etc.?
 
I was digging....i have found some of space guns documents. Can these help?

Hmmm,looks like there have some differences.
At this manual K connector are different from the info of KLOV manual and all other manuals form the web,which are same.


The manual from the web(left for P1),in the middle(for P2) and the one from here(on right).
I know that this one here is original,but when I wired my machine I used the one from the web.

I'm a little late to this thread, but I just finished putting a Space Gun together. When I was done I had two perfect working guns but after one day of play the solenoids barely function. I really don't understand what would cause this... was wondering if anyone had any ideas. I saw someone here said the guns share parts with T2... I am not sure that is true but I found a source for the T2 solenoids so I ordered some. They are certainly not the same coil but they activate at 20vdc, and looking at the documentation here it looks like Space gun uses 24vdc for the guns... so hopefully they are compatible. I'm not convinced there is anything wrong with my coils though.

I also wanted to add to this thread, that there is no grease in the solenoids, and that the "old grease" people are cleaning off them is actually rubber that has turned gooey. Here is a picture of one that is intact. It's still a tad sticky for rubber, but it functions as it should, as a bumper. I don't think running these without some kind of rubber there is a good idea considering the kind of wear it would create slamming the metal against the coil over and over.

Space gun - player one coil always energized

Hi

I have a space gun where player one coil gets energized when I turn the game on.
When I press the fire button it stays energized, the game fires as normal on the screen.

For now I just have cut one wire going to the coil, because it got wery hot.

Player two coils works fine.

I assume that there is a transistor on the main pcb that controls the fire action to the coil.
But I have not been able to find any schematic on Space gun arcade.


Does any have some schematic or know how to fix the coil issue?
 
Let me see if I can help you! I wont be able to look at it until about 7pm EST. I see you are in Denmark. So basically, if I understand what is going on, this is what is happening:

One of your gun solenoids just immediately energizes as soon as the game turns on. It does not matter if you pull the trigger, it just stays locked on. The solenoid doesn't act like if you are holding the trigger and shooting the gun(making the feedback feeling), it just continually energizes the coil and holds the plunger in place. Thus getting the coil very very hot in a short period of time.

Could be a shorted transistor on the pcb in the gun control area.... Ill have to look inside mine to further help you.

Hi in99flames

I have now found the bad IC, that causes player 1 coil always to be energized.
It is IC82 an 74LS32N it testes bad.

But I need you help - Is it possible that you can take a picture of the back of your PCB where IC82 is located?

Because this time I removed the IC I have broken a couple of traces, normal I take picture before I start removing chips, but not this time - and now I am unsure where the broken traces are needed to be connected.

I hope that it is IC82 - I am waiting for some new 74LS32N IC's
I have also tested the transistor, it tested OK.

Kind regards
Per

I had recommended he check the 2SD633 associated with that particular gun. I got a gut feeling it is shorted causing the coil to energize indefinitely.

Thanks for the tip :)

I have checked the one to player1 it is fine, also the diode.
I back tracked the parts from the connector, and coil1 in the manual.

Might be an idea to check the player2 diode also now ehen I hace the pcb pulled out :)

Ok cool! So the transistor isnt shorted. Good. Well I was wrong [emoji14] but we know that the 74ls32n is looking like it is bad so ok ill get you pics!
