I picked up an old GE Center Cab 44 ton diesel (HO) at a local swap meet. It is an AHM 4-wheel model dating from the 1980s or 70s, I believe. It is a bit of a hesitant runner, but I believe it holds promise. When I opened it up, I found what looked like steel wool fibers all over the motor and the side supports, as well as other accumulated crud. There are two light lenses fore and aft, but when I opened it up, only 1 bulb in the front, and it was flickering when I ran the engine. Should I replace the existing wire that appears pretty brittle? Should I use LEDs and replace the small bulb, adding a second one? (and how to wire that properly?). I also read that 100% synthetic ATF fluid makes for a good re-lubricating method, but where?
Advice is requested on the best practices for cleaning the wheels, as I have researched conflicting methods. Also requested, best method for generally cleaning the motor assembly as well and improving electrical contact.
Thanks in advance for any feedback.

I've used a Walthers "Bright Boy" for cleaning the wheels. It's a hard rubber with a super fine abrasive mixed in. Others have used alcohol for cleaning the wheels.
Since all the gears and bearings are plastic, the ATF fluid can be used for the whole thing.
I have one of these AHM Center Cabs too. The light wire does seem brittle, but it's actually held up very well. As long as the bulb works, you can keep it.
Mine never ran well at low speeds, and the traction wasn't as good as I liked with its single axle drive. So I replaced the whole mechanism with NWSL Flea gearboxes, a couple gears, and an extra Mashima motor. It's a bit noisy, but it runs really well now!
