Issue wiring a 6-lead single phase motor to an 8-pin control relay

I have tried to wire a 6-lead single phase motor to an 8-pin control relay. I could not attach the pictures, because it is complicated process just to do so in this forum, where I am new, as compared to others. Maybe someone could tell me how to do that. I have connected the terminals ( T1, T2, T3, T4, T5, T8 ) coming from the motor and the wires labelled 513, 514, 515 and 2M as follows:

Wire nut 1 : T2(White) + T4(Yellow) + T5(Black), (514) + (2M) joined together.

Wire nut 2 : T1(Blue) + T3(Orange) + T8(Red) + (513) + (515) joined together.

However the circuit breaker CB503 keeps tripping and the associated fused has blown. I would like to know what might be the issue with my wiring.

Thank you

I am familiar with the T1 through T8 wires, but not the 513 through 2M. Are these to the relay? And what voltage are you applying and to which wires. Finally, how are you energizing the relay?

Really need the diagram. An easy way to post it is to use the windows clip function and just paste from clipboard into a new post.
Thank you for your answer. I have tried attaching the pictures to my post, but I keep getting the message "Image cannot be loaded from the passed link". Please do you know how to overcome that issue?

Try taking a picture of the diagram with your phone and post the image here.

Thank you for your answer. Honestly, maybe it is because I am a new member, but I have tried every single method I know of, and used successfully on other forums with no problem, to attach the images along with my post, to no avail. Very frustrating

You could try reducing the file size of your picture.

Picture or not - What are leads 513, 514, 515, 2M for? I would leave them out and try the motor.
Thank you for your answer. Without a picture, it would be difficult to explain. These are connexions inside the control relay. All the wires I mentioned in my initial post are necessary for the wiring. There is nothing to be left out. This is not an option.

Very frustrating. I do not think the size of the images is the issue. I have uploaded the same images on another forum with no problem.

It may have to do with you being a new member. Don't give up yet. Wait 30 minutes and try again.

Is this a new motor replacement.
Post pic of old motor diagram.
Looks like you have a single phase reverse relay.
The motor is the one currently in place and it was operated manually to move another equipment, which is the issue I am trying to resolve.

I do not have an old motor diagram. All the information available to me has been provided in my post. I am just trying to understand the reason my wiring keeps blowing the fuse protecting the circuit even though it seems I did it correctly according to the electrical diagram I was provided.

The relay is a motor direction revealing relay. Should have a timer in line to keep for reversing to soon and damaging relay and motor. Make sure it stops completely before reversing.

Thank you for your answer. However, I am confused because the wiring diagram on the motor's nameplate stipulates that, for low voltage, to also connect (blue+orange +red) and (black+yellow+white) respectively TOGETHER. To me your answer seems to insinuate that the red white wire should be connected to 514 and the black wire to 515, but separately. Am I mistaken in my interpretation of the wiring in the nameplate?
