The resistance is low but OK. You now need to check the voltage across it when you trip the coin lever. You need to attach your meter, set to AC volts across the coil terminals. This has to be done when the mech is back in, which can be difficult. It helps if you have small clip-on test leads. You s...

The next step is to check the solenoid resistance and the voltage across it. With the mech pulled out, check the resistance across the solenoid. It should measure about 12 ohms. If this is OK, let me know, and we can move on to the next step.

So let me get this right, you trip the coin switch but the handle is still not engaged? Just confirm this and we can move forward. If this is so, then you may need to adjust the end stop on the solenoid. One other thing, do you have a test meter?

Green is always earth, so connect them together. The red on the Sega is the live. Connect this to the black on the USA lead. The black on the Sega lead is neutral. Connect this to white on the USA lead (white is neutral). The best way to do this is to remove the old mains lead completely, and resold...

Ok, Mr coppinpr is correct. :cool: The first thing you must check is the main solenoid closes when you trip the coin switch. Someone at sometime has rewired your machine and for some reason has modified the dropper resistor to the aforementioned coil. I think I know why, but won’t muddy the water by...

Hi, can you post pictures of the back of the mech and the front of the mech. Particularly the small circuit board mounted at the back of the coin mech, which looks like someone’s had a go at.

Hi mike, sounds like it has not been pulled out for some time :roll: You say that you have undone the upper wing nut and the 2 bottom clamps , that is all that is holding it in, it may be stuck in with old grease. It should come out if you give it a tug. There is a handle inside at the back to pull ...

The 2 bulbs on the door will be 30 v , the coin denomination light may be 6v or 30 v depending on your version of machine.

Some of these Windsor machines had a 6 volt tapping to supply the coin light. All other lamps were 30 volt.

Hi, my Sega Windsor uses 30v 0.15a bulbs. These machines use a 30v ac supply.
30v 5w bulbs can also be used.
It is possible that someone has used the wrong bulbs in the past, don’t let this throw you.

Sega Windsor now fixed ! As I was not able to ascertain the correct solenoid I made my own :cool: The original solenoid coil had gone short circuit due to overheating and measured just 0.4 ohms, to find out the correct resistance I carefully unwound the coil, which was 77 metres in length. I then me...

Yes! this is for testing electrical leakage currents between two conductors.
500v is still used today for this purpose.
In simple English, it tests the insulation between two cables. JC is correct, it is not a resistance meter.

Good god, All I can taste now is metal, it certainly cleans your tongue up
As I have said previously, my solenoid is no more, it has ceased to be, all I need is someone to help me find a replacement or give me the part number that is written on the coil sleeve.

Oh yes, I think 'capacitive coupling' rather than 'resistive short' would be my explanation.

This is all very interesting :cool:my solenoid cable is knowhere near the lighting cable, I have had problems with noise being induced on my hi fi when cables are run together but would have thought that there would not be enough current induced to operate a coil, even slightly, but hey , I have bee...

Would love to add photos but can't work out how to do it on this mac

Oh yes, regarding AC and DC, this machine only uses AC , there are no rectifiers in the machine

I know the power supply rail is 30v ac but the supply to this particular solenoid is dropped across a 10watt resistor, so the voltage is much lower to operate the said coil. I can't understand the reason the manufacturer did this ,maybe they had some low voltage solenoids they needed to use up ? !PU...

If someone out there has one of these machines I would be grateful if they could tell me the part number of the coil,usually printed on its sleeve.

I did many checks and I know the fault is the coil being short circuit, it has overheated at some time, not helped by the ciggy paper wrapped around the 2 amp fuse
Clearly the coil had been causing the fuse to blow as it grounds the supply voltage as soon as it is connected.
