Thank you!
The link to the diagram was very helpful!
Have a great day!

Recently, I purchased an HO model of the 1832 Dewitt Clinton.
The Ebay seller stated, in the auction, that the motor doesn't run.
I took it to the local model railroad club where they have their HO layout and a test track.
I hoped they might be able to take a look at it.
The man I spoke to was cautious not to try working with it as he was unfamiliar with it.
Is there somewhere I can find a guide to servicing it?
When it was put on the test track, there was no sound (hum,/buzz, etc.,..) coming from it.
does anyone out there have any experience in working on this model?
