Well, I couldn't have been more wrong on these repairs being just battery terminals. These so far have been the most challenging for me so far.
There are the following to be repaired:
- TnA Thomas x 3
- TnA Henry.
- TnA Gordon.
I have looked at two of the Thomas's and while they had great battery terminals the member had attempted some repairs. I applaud the attempt but in order to repair I am needing to de-solder all of the wires on the circuit board. I started in on this but am needing to get some more wire which I ordered from Amazon. I got a bit frustrated with them and moved on to Henry. I figured re-doing the battery terminals would not be too bad as I have done several. I got all of the terminals out (see before and after below) and while they were drying after cleaning with white vinegar and water I had a look at the engine. While in the on position the wheels spun so I figured it had a stripped gear. Upon taking it apart I discovered more repair attempts and while not as bad as the Thomas engines I had looked at it was pretty bad. Then I discovered ther was no motor, no gears, and the spring for the activation mechinisim was gone.
Never fear though, a donor TnA British James was in the spare yard. James, Henry, and Gordon all have the same style motor assembly. I removed the wires one at a time from James, soldering to Henry as I went. 2 hours later and Henry (just the engine) is back together and working. Just need to get the battery terminals in and make final connections.
Once Henry is done, on to Gordon.
Here is the before and after of the Battery Terminal a rear after being cleaned up.
