Hello. I found my 6 pin molex to the motherboard has a burn mark on the connection. What I have to do to change the burnt connections? :Please_Post_Pictures_2clr:
-
I would try to clean it first. Something lightly abrasive. The pin and inside the connector too. Oxidation or looseness can cause this. A little cleaning might do it. And easier than changing a pin where you are.

Okey. So I have to pop them out from the white plastic house and clean them whit electro cleaner?
-
The last time I did one, I sprayed it with electric contact cleaner and kind of cleaned it out with something small like a pipe cleaner. Sometimes you can spray them and plug and unplug them a few times to clean them off. I don't know what you have but look around for something small enough to clean them.
-
So I dont have to remove wire from the white plastic house?
-
If you can't get to it well enough, then you may need to remove it from the Molex connector. The black spot is from heat. If you can clean the inside of the connector without removing it, that's what I'd do. If you do remove it, try pinching the connection a little tighter. Or if it looks really bad then replace it.
-
Thanks. I do that tomorrow
-
Also some of the vendors on here sell the entire plug as a pig tail. Just splice the wires and you're done. Rudy's Deals (on the home page) used to sell them.

One sure way to correct the problem forever is to cut the wires off the plug one by one and solder them on. The reason is because of heat as shaggy mentioned. I have done this in the past and you will not have that problem due to bad connection.

I don't have this type power supply harness on my machine.

I wondering what type contact socket I need to change out the damage on my 6 pin molex to motherboard. I found this type on ebay:
1. Contact socket, 20-18 AWG crimp MPN: 85-20-112 molex
2. Contact socket, 26-22 AWG crimp MPN: 08-50-0185 molex. How its the right type contact socket?
-
Can some one tell me the type of this 2 contact socket are right to the 6 pin molex connector? :Scratch-Head:
-
If you don't have the 6 pin power harness you show, what do you have?

:I_agree_1:
:me_too:

I have to old IGT slot machine. One are from 1989 and second are from 1992
-
You have a early model splus.
That plug is hard wired into it
You would have to cut and solder one back on
-
Someone have pitcher how I do that
-
Are you talking about the 6 pin Beau plug the hopper plugs into or the Molex plug on the right side of your pic (more than 6 pins)
Let me know....

I takling about the 6 pin molex to the motherboard
-
I dont know your experience... but if your asking how to replace that connector, you might be kinda new to this. Can you let me know what makes you believe that it needs to be replaced? What did you check? If this really needs to be replaced, I will PM you and you can call me and I will walk you through the process. Nothing big at all...

Looks like someone cut and repaired the orange wires. It is the green that usually burn. The front of your plug looks super white. You need to pull it off from the MB to see if it is burnt. If the machine is turned on, are the reels stiff or turn freely?
-
On the white plastic house to the 6 pin molex are litle yellow color from there the green wire are. I have cleand the the molex connector whit electro cleaner spray werry good
-
Can you post a closeup photo of this molex connector so we know what you have and what you need to do?
-
Here is a photo of the connector. Is it bad or not?
-
The connector housing (white plastic part) is not bad and there is no need to replace it except for appearance reasons. But it shows a browned area that indicates that 1 contact inside the connector housing has been over heated. You can remove that contact while it is still attached to its green wire and inspect it, possibly clean it with something by scraping off the tarnished surface of the contact. I'd try something like fine sandpaper, small file or knife blade. The tarnish can not be removed with liquid like contact cleaner or simply wiping it with a paper towel.
If you are not able to clean the contact well enough then you cut it off from the green wire. Then remove some of the green insulation (about 1/4 inch) and attach a new contact to the freshly exposed wire. The new contact can be crimped to the wire but you would need the correct crimping tool. As an alternative you can solder the new contact to the wire.
The contact is held inside the white housing by a springy leg or clip that is part of the contact. You can depress it slightly thru a small opening on the side of the white housing and pull the contact out of the housing. To reinsert the contact simply orient it correctly and slide it into the housing until you hear it lock into place.
There is probably a video on youtube showing how to work with these type connectors. They are commonly called Molex connectors, after the name of a prominent company that makes them. If you are not able to do this repair then find an electrician in your area, he will probably be able to do it for you.
Below is a photo of a typical Molex contact, you can see the little spring arm that locks the contact into place when it is inside the connector housing. To remove the contact your press in on the spring arm and slide the contact out of the connector housing. This is easily done while the wire is still attached to the contact since you can pull on the wire while pressing in on the spring arm.
Keep in mind that this overheated contact was mated with a male pin on the motherboard when the connector is plugged in. That male pin probably also has tarnish and should be cleaned. Repair should be done to both the connector contact and the male pin it connects to. Look for darkened areas on the male pin midway along its length, that is where the female contact inside the white connector touches the male pin on the motherboard.

That is the tell tale sign. Very minor color. Do you know how to use a very small probe to remove the pin from the connector? You can remove the pin and replace it with a better pin. The original pins only touch 1 side of the MB pin. The new ones touch 3 sides. One of our long time members has this listed http://www.ebay.com/itm/IGT-SLOT-MACHINE-S-plus-POWER-CONNECTOR-REPAIR-KIT-/152386783386?hash=item237af5c89a:g:EgcAAOSwt5hYcOTs (http://www.ebay.com/itm/IGT-SLOT-MACHINE-S-plus-POWER-CONNECTOR-REPAIR-KIT-/152386783386?hash=item237af5c89a:g:EgcAAOSwt5hYcOTs)

Okey. So in don't need to replace it? So the connector are not burn?
-
How did you get to that assumption? Yes it is burnt and needs repair. You have been told how to remove the connector from the molex. Remove it, clean it, bend it, replace it, whatever it takes to get a good contact.
-
Okey. So in don't need to replace it? So the connector are not burn?
:Scratch-Head:
I think you are going to need to find someone near you to help you with this. It has been explained fully, if you are not able to understand the advice and suggestions given to you then hopefully a friend or repair person near you will be able to help. Good luck with it!
-
I am willing to help you as I stated earlier if you want. The connector is not bad, and the pin for the darker area on the white plug, only seems to be a little faulty and I cant see that this is a fix to a machine not working. It will help it in the future but the look of it, doesn't show a problem. Very easy to replace the pin inside the white connector. PM me and I will provide a # to reach me at one more time.

I have a feeling he is in another country maybe.

Correct, Norway. :yes:

I knew there was a language barrier.

My machine works perfect now. I just used some fine sandpapir to remove the oxidation and cleand the connector whit some electro cleaner and no its shiny like new. The connector was NOT burned, its was just dirty. So I will thanks all off you fore all help. Tropic svolved :propeller: :dancing_2: :thank_you:

Glad you got it going. :applause:
