Knocker Coil Issue

[Slash]

Thought I would post a video of the knocker coil, sorry the video is sideways the coil is installed vertically, but it gives you an idea of what's going on. It just can't seem to hit the end to make the knock noise.

On a separate note shortly after I got the knocker coil working (albeit pretty pathetically) the game decided it doesn't want to let me play it anymore.  When I turn it on it appears to go through the start up procedure with no problems but it won't let me start a game when I hit the start/credit button.  I was playing a game when it first happened and it just stopped working like I had tilted it, but now it won't let me start a new game.

The button/switch is fine because I can use it when going through the diagnostics/menu etc.

I have done a video of the start up procedure to see if anybody can spot anything dodgy.  I have run through the switch as well as coil tests and everything appears to be fine???  I'm ready to put this POS on the verge

You've got the plunger upside down
The plastic bit is supposed to strike the frame not the other end

Is the game in freeplay?
You don't have any credits displayed so if it's not i freeplay then it won't start

[Slash]

lol - is that right re the plunger.  Rookie error    I will switch it around now.

Second rookie error no credits.      I'm not used to having to do that, I wonder if the pascal board has a free play setting, I will have to read the manual.

Funny how a video can trouble shoot stuff in seconds. I appreciate the help.

Just gotta find out why my vari target and star rollovers have never worked and then I think it's all good!

[Boots]

There is definitely a freeplay mode, it's one of the great extra features with that board.
I believe the Pascal board displays "99" in the credits when it's set to freeplay mode.

[Slash]

Cool I will have a look for it now.

Just swapped the plunger around then and it's knocking beautifully now.

Sorry, but a had a chuckle at this.

Glad I can give something back to the community 

In my defence re. the knocker coil, I put it back together exactly as the pictures I took before disassembly.  I should have known better as whoever tinkered with this machine before me put quite a bit of stuff on incorrectly, e.g. the pop bumpers were wired in reverse when I got it (I found out about that the hard way too).

[Steevsee]

To be honest, I didn't pick up either of the issues myself.

Good eye Boots.

I contacted Pascal at FLIPP regarding the board and he said what Slash said above, it is the tran at Q1 for the knocker coil.
As you will see by the attached picture it really is that transistor, the big hole in it gives it away! ;)

Interesting thing is I was getting a second coil warning which I thought I detected by disconnecting the wires to the left slingshot coil.
Pascal informs me that the slingshot coils are not CPU controlled and fire directly from the switch which makes this problem interesting, the problem I have now is that the displays have failed and unable to go any further until they are fixed. it seems there is a short in one of the displays. Trick here is the fuse on the board has done it's job and blown and I have One spare! to test the displays by disconnecting them and trying them one by one, good-bye spare fuse!

I will order some spare fuses and extra transistors and diodes from Pascal then I can move forward and check whats going on with the coil warnings etc. Euro and Shipping is a bit hexy but got to do what you got to do and so close now! :)

Cheers: Brettski... :)

[Boots]

Can you temporarily fit an inline fuse with a lower rating than the pascal fuse?
Do you have another sys1 to test them on?
Have you visually inspected the displays or tested them with a multimeter?

Mate that looks nasty

Hey Brett, Sure you can't get the parts locally? The fuse must be fairly standard I would of thought?

[Brettski]

Here is a pic of the spare fuse, it is a 100ma. The original is supposed to be 80ma. The tiny little prongs make it quite limited I think.

It is a two prong fuse and small as you can see but I don't know where to get them locally, I tried Jaycar but no go and couldn't find them at RS-Online.
It would be good to find the other components locally and in one place but I haven't had any luck. You might have better resources Dan, here are the parts Pascal has available. http://www.flippp.fr/spare.php

Chris I have another System 1 (Sinbad) with a Ni-Wumpf board but how would I go about this without causing trouble with this board? Let me know what you had in mind here as I might not be thinking about it right! :)

It does look Bad Pinball God! All was good except what I described above so once the displays are sorted out and Q1 replaced we will see how it goes! :)

Cheers guys appreciate any thing you can suggest here.

Cheers: Brettski... :)

BDW93C readily available from RS Components..

That's a PCB fuse.. RS should have them. If not can solder in any fuse
