Sega Windsor Playboy machine

Did what you said and when tripping the coin switch it had no effect on volt meter. The volt meter did read 0.264 before tripping it if that means anything.

[radiochrissie]

So you know the coil is OK but you are not getting the correct voltage across it.
The next thing you need to check is the supply voltage which should be 28 to 30 volt. This voltage should be across the grey and blue wires which come from the transformer secondary.

If you have 30 volts across the circuit you may well find that the safety relay has failed.
Someone has rewired this machine at some time so it is clear there has been a problem that someone has tried and failed to fix before.

[trops79]

In order to check the supply voltage I believe it needs to be plugged in correct? How can I get to the wires while it’s in the case?

[radiochrissie]

You can check the supply voltage with the mech out: Trace the blue and grey wires coming from the transformer to the connector at the rear of the case. Check the voltage here first.

[trops79]

Here’s a photo of the wires. The grey and blue go different directions. Maybe it’s different on my machine?

[radiochrissie]

The grey and orange is the 30 v supply, the pink is probably the 6v tap.
If you have the correct voltage here the fault lies with either one or more of the mech switches. These can corrode over time causing a high resistance. The fault could also be with the safety relay. Worst scenario is that it is caused by the rewiring someone has done. The only way to sort this out now is to check every switch contact and compare it to the circuit diagram. It is fixable but it takes time and patience.

[trops79]

Thank you for your patience with me!
Anyway, I checked the grey and orange with the volt meter and it reads approx 14.9. Plugged in of course.
Could it be the lame connection - see photo.

[radiochrissie]

Someone has clearly messed with this.
The voltage you measured is clearly incorrect. This may be a daft question but you said that you are in the USA which is 110 volts, if the machine is still set to 240v it will cause this problem.

[trops79]

Yes in the US. If the 240/110 is the problem is there something I can do? Buy an adapter, etc??

[radiochrissie]

OK, so it looks like this is your problem. I would suggest you rewire the transformer input to take 110 volts. This is very easy to do as long as you follow the wiring diagram posted earlier.

[trops79]

I’m “electrically challenged”. Lol
What would this consist of? Please explain in the simplest form.

Here’s a pic of the transformer wiring. Btw I checked the volts coming out of the transformer and it was about 120.

[radiochrissie]

120v is going into, NOT coming out. You need to reconfigure the input for 120v use.
This is clearly shown in the schematic. If you are unsure about doing this yourself, you will need to get someone who does.
This is mains voltage and needs to be wired correctly and your safety comes first.

[radiochrissie]

Sorry, if my post above comes over like some schoolmaster
Would pop round and do it myself if you where a little closer.

I must say radiochrissie is doing a great job helping with this machine, a prime example of what we do well on this site

Definitely a case of getting someone in to do this part of the fix. It's not a big deal for someone who knows but never worth taking chances with something that bites back.
What you need is not really a household electrician - more like someone who works on Hi Fi or older type TV's, radios repair etc. As all the correct ports are already on the transformer it would take him about 10 mins to do and you would know it's right.

[radiochrissie]

Thanks for that coppinpr, I think we all gain something when we help others.

[trops79]

I very much appreciate the help! Unfortunately I need to take baby steps...mechanical slot machines I’ve pretty much mastered but this electrical stuff is like learning Chinese for me. Lol
Anyway, I tested the volts (red and black wires) after the transformer in this area (in photo) and it was approximately 120. Isn't that after the transformer?

[radiochrissie]

No, that’s the INPUT to the transformer primary, which in your case is 120v.
The output or the secondary is shown at the bottom of the transformer.
What’s needed is that the transformer primary has to be adapted to take 120v. At the moment it’s set up to take 240v. As you're only putting 120v in you are only getting about half the expected voltage out.
If you look at the transformer where the black and red cables are you will see 8 different taps or connections. These taps have to be configured in a different way for each type of mains input voltage. Look at the schematic and you will see the setting for 120v.

[radiochrissie]

Actually the setting you need is the 110v in your schematic.

[trops79]

OK I'm starting to "get it" now. So I need to run a new cable (old one is spliced and old anyway) from the outlet to the transformer utilizing the correct volts indicated on the transformer right? I think I'd like to try it myself. If I took a close up of the schematic and the taps on the transformer - could you point out where to attach the new wires? Don't worry, I wont blame you if I light myself up.

[radiochrissie]

Go for it, I will help.
