RSM tyre truer requires adequate power supply such as Kelvin Light.

Tru-Speed Slot Car Diode controller.

Features:
3 overall sensitivity settings
10 Element/torque adjustment switches for innumerable permutations.
4 Brake adjustment settings.
.LED for Power, Brake, and continuity tests.

Each of the 2 sensitivity switches feed 0.5V more to the element as they are switched on.
Both OFF:Minimum
Either ON:1st stage added
Both ON:2nd stage added

The 10 element switches each change to voltage between each stage from 1V to 0.5V when switched ON.
These give you control over the response of the motor to different throttle positions, enabling torque control and ease of car handling for any track circumstances.

The Brake control slows the motor fast as if with full normal brakes, but then releases at 3 different stages to give a controlled coasting effect. 
Both ON:Full brakes
Inner OFF:1st stage coasting
Outer OFF:2nd stage coasting
Both OFF:3rd stage coasting.

The LED shows power present when initially plugged in with NO car on the track, and illuminates provide the brake switch is OK.
The LED will extinguish when a small movement of the trigger opens the Brake contact, but will re-illuminate when the car is placed onto the track.

This provides 3 useful tests with just one LED!
