hey guys, had this problem for a while but when you insert a coin, 1P start lights up for a second, then the game restarts, otherwise everything is fine on the game. There is no free play dip setting so this game works but is unable to be played since i picked it up, which is driving me insane.
 
What game is it? Most of the games manufacturered by Gremlin were designed to reset this way before starting a game. It was a logic clear circuit. Some early Sega games did this as well.
 
It's cosmic guerilla, i refrained from posting the name because i asked this before and i did not get any responses, i assumed it was because not many people have the game, so i was hoping if i was a little more general i might get a lead.
 
Looks like it is manufactured in '79 by Universal

Make certain the coin switch and index lamp are not connecting when a coin is registered.

On the above link and inside the operators manual, You want to look on page 22. There is a 4 pin connector with the coin switch and a light. If they are wrong it will cause a short.

ive checked out this diagram before, and none of the colors match up to what they show. i have two black wires, one coming from a light and one from the connector, an orange wire, and a black wire with an orange stripe on it,
 
Ad addition, i traced the wires back again to find out which colors matched.
1 = pink
M = pink
9 = black and orange
10 = black
the 4 pin connector has 2 pinks going in, and one pink going out to the coin door and it is hooked to a light bulb, where i always get stuck at is the orange wire.

On the board connector, if i trace the orange wire, it goes to pin K, as you can see on the diagram, it doesn't show anything on pin K,

If i follow the diagram, the pink wire goes into the light, then on the other leg it comes out from a black wire and goes to C, then the orange and black wire connects at the C or CON leg on the coin switch, if there was a second pink it would go to NO on the coin switch, but there is no second pink wire. and at the NC leg of the coin connector, the black wire that is not connected to the light bulb gets connected to it. Where is my other pink wire and what is the orange wire?

what you need to do is take pictures of the harness and the wires to the switches and post them...i was looking at the schematic..and i understand the schematic..but not the colors or the way your telling us it's wired...sorry :(

Pics always help; something about 1k words and a pic or something....

You are making this more complex than need be. most of the wires should be ground and one maybe two (I don't remember) should have some + voltage on it. Just use a simple volt ohm meter to test each wire for voltage.

I bet if you ohm the light wire with ground (while all power is off and unplugged) and toggle the credit switch you will get 0 ohms.
 
Is there a reset switch inside the coin door? If so try cycling it to see if your machine coins up.


It appears that your colors don't match the schematic, this is not very uncommon for games of this era. Trace the wires, either hand over hand or preferrably by continuity checks with a multimeter.
 
in the current configuration like the picture, which is as close to the diagram i can get without the 2nd pink wire, hitting the switch just turns the light bulb off
 
Hitting the switch should not turn the lightbulb off. With the game on check for voltage on both sides of the light bulb. The wire that goes back to the 'com' position on the switch should read 0vdc and the other side should be somewhere between 5vdc and 12vdc depending on circuitry.

I thought so....

Ok you need to ohm out the micro switch to find out what is what. I think the outer connectors connect when there is a credit or switch is activated. The inner one (center to bottom) is always connected. I suspect the yellow wire is your voltage and should not be part of that switch....I think.... You need a meter to be sure.

The orange wire in the picture that is not hooked up to anything tests at about a 3v, if i hook it to the NO post on the coin switch, the bulb dims when i hit the coin switch, but will not register a coin.
 
Do all of the lights go out or just the coin door light?

Pull that bulb out and try to coin up. What is the bulb number?


What is the voltage you are reading at the NO and NC locations (should be approximately 5vdc, possibly less).
 
the voltage at nc and no are 0 currently there is nothing attached to NO, and for clarity, after the diagram i rewired it, it no longer restarts, it just will not coin up at all. Only the bulb in the circuit goes out, and it is rated 6.3v 0.15a when i remove the bulb, it does not do anything different. The loose orange wire, is 3v, if i hook it to NO, the bulb dims, but still does not coin up.
 
I looked over your pic again and here is how it looks to me:

Black/orange is wired to Com. Also on Com is a black wire going to the light.
There is a black wire on NO.
Nothing is on NC.
There is an extra orange wire not connected to anything.
There is a pink wire going to the bulb.

Is this correct? What are each of these wires also connected to?


By the way, the reason the bulb is dimming is you are effectively reducing power across the bulb from 6v to 3v by inducing 3v on the return leg via the switch. This is not correct.
 
You have them backwards, nothing is on no and the black wire is on nc. The black and orange wire is from the wiring harness at the board pin 9 the pink wire is pins m and 1 they go into the four pin connector and only one wire comes out and it goes to the bulb. The other leg of the bulb is black and is going to com with the black and orange wire. On nc is a black wire which is pin 10 at the board. The orange wire is loose, has 3v running through it and is on pin k at the board.
 
OK. I don't see why M and 1 are connected. From looking at the schematic you should have the following connected:

1 - NO
10 - NC
9 - COM and bulb
M - bulb


M should have a branch that heads down to a 9 position connector as well.
