Som du nok har opdaget, synes Teknatool ikke, at man selv skal pille, så de har ikke offentliggjort et diagram og giver ofte alle ledere samme farve.
Det her er et udpluk fra forskellige kilder, og det meste er sort snak for mig, men måske er der et stikord eller to, der kan hjælpe dig videre.
God kamp!

Teknatool does not publish an official wiring diagram for the NOVA Comet II Midi Lathe. The manufacturer classifies the control box as a "Y-Type Appliance," meaning all electrical components and internal wiring are restricted to factory-only service. Furthermore, Teknatool often utilizes monochromatic (same color) wiring inside the switchbox, making visual diagrams difficult to standardize.
However, if you are attempting to diagnose a power fault, replace a broken On/Off switch, or wire a replacement Permanent Magnet DC (PMDC) controller, you can use the standard schematic logic outlined below.
1. Main Power Switch Connection (DKLD / KJD style Magnetic Switch)The Comet II utilizes a safety paddle On/Off switch (often a standard 4-terminal or 5-terminal NVR magnetic switch):Terminals 1 & 3 (Input Line): Connects to the incoming AC main power cord (Live and Neutral).
Terminals 2 & 4 (Output Load): Sends AC power directly to the internal variable speed control board inputs (usually labeled L and N or AC1 and AC2).
2. Variable Speed Board to Motor RoutingThe variable speed controller rectifies the incoming AC voltage into adjustable DC voltage.Motor Outputs: Look for terminal outputs labeled M+ and M- (or A+ and A-) on the control board.Directional Toggle Switch (Forward/Reverse): The M+ and M- lines route directly through the center pins of a Double-Pole Double-Throw (DPDT) toggle switch. Flipping this switch crosses the polarity of the wires before they reach the 3/4 HP DC motor, allowing it to spin backwards.
