I want to use Parma controllers with my Carrera set but keep the existing wiring, got any diagrams or hook-up instructions?
From alt.hobbies.slotcars – I’m using Parma controllers with my Carrera set. Here’s the mapping you’re looking for: —– | | | — | ( Black (to track) | — | | | | | | | | | | | — | ( Red (brake) | — | | | — | ( White ( to power supply) | — | | —– FYI. Carrera connects their power wire (white) to the negative side of the power supply. Almost everyone else connects the power wire to the positive side. With a resistive controller it doesn’t make any difference, but with an electronic controller (which Carrera makes) you must follow the manufacturer’s method.
