Really need a pic but if you are getting readings across the resistors then I would test the clock by attaching a 12v supply to it. One end of the resistor connects to the capacitor and the other end to the 12v supply, unfortunately I do not have a spare clock to photograph but as I said, test the clock with the new capacitor fitted.

Just read your pm, you can post a photo when you reply, the last icon above this text is a black square with an i in it, click on that and you can insert an image - you will be prompted to go to the location where your image is stored.

The resistor with a measured resistance of 122 ohms is the resistor that fails if the capacitor goes short circuit, yours appears to be ok so just go ahead and re-fit the clock. If you want to test it before re-fitting, the large tag is the positive and the one you had to unsolder to remove the clock assembly is the negative, if you look closely you can see a negative symbol close to it.

When re fitting the capacitor make sure the positive and negative legs are soldered correctly regards polarity.

Great. I really appreciate your help with this. Thanks
