I think you might find some useful information in this thread of the forum: https://www.marklin-user...-My-Faller-AMS-addiction

Hi (a first name maybe?)
A warm welcome to this forum of train fans
Here a French enthusisast of Märklin and Faller. Long time ago, I use to have a Faller AMS car system but not anymore.
What I see are elements of the Faller AMS (HO-size slot cars) and sold in the years 1965-1975.

Can I made my own transformer (power supply) and what voltages it must be AC or DC and what options
The cars were definitly DC
Faller Transfos were 16 VAC (16 VA I think) like the 4016 (in the 1976 catalogue
Attention you must have a rectifier between the transformer and the car (Faller 3808 in the 1970 catalogue or early (1965-1968) large controls with a rectifier to select the wave side and controls for lane switches
There were special sliders with a rectifier (4893) allowing to control independently 2 cars on the same track
In absence of these rectifier-sliders, a simple diode 1N4007 or equivalent allows to do the same trick.
By swapping the magnets it was possible to make a car use the upper or lower portion of the sine wave and still go forwards



-how to hook after that the wires/jacks.
Underneath the tracks, it is possible to solder a wire for connection in absence of the double track feeder referenced 4702

Track cleaning
These tracks may oxydize easily and the cleaning trick was to use a small metal rectangle to gently swipe all oxydation

Here is my layout with the newer version of the Faller Car System

Hi
From what I see on your video, tires and sliders need replacing (Tire gum is hardened, sliders have grooves)
By serach "Faller AMS ersatzteile" I found this
https://slotcar-online-s...e/faller-ams-repro-teile
Probably you may find more as there are many Faller AMS enthusiasts in Germany
Cheers
