HO Alco Models/KMT EP-4 short circuit

[haberbeckbrandao]

Hello!

I need, if possible, some opinion regarding a problem with the assembly of a HO brass locomotive.

I bought an Alco Models/KMT EP-4 electric several years ago. It was recently painted with the NYNH & H scheme and had to be completely disassembled.

When proceeding with the assembly, I am experiencing a persistent short circuit and I am not able to identify the origin.

Apparently the problem arises when making the electrical connection of the motor with the bogies. The original motor is OK, and there is no short circuit in the mounted bogies when supported alone on the rails.

Is there (or was there) any Alco / KMT documentation of the model, such as an exploded view or an wiring diagram?

I will wait for an eventual feedback!

Thank you.

A clear photo of the model's bottom would be good.

Hello Toptrain1, how are you doing?

I would like to thank you very much for your feedback.

Fortunately the solution to the problem on my EP-4 was found about 3 months ago, through another forum.

I think it would be interesting if you can read the history of the subject.

The engine is running perfectly!

Have a great Sunday!
