WARNING: This guide is meant to be printed out and handed to an electrician in case they need it. Do not attempt the work yourself, especially if you have not done electrical work before - stop reading and call a professional to do the connections for you. If you have no idea what you are doing and create something dodgy it will kill a family member, a friend or you. Your safety and any legal claims rest with your electrician.
Disconnect the battery before starting.
Connection for a 12V DC on/off rocker switch with 3 terminals:
1. The positive terminal (marked with “+” “A” “1” etc) connects to the positive (+, red) terminal of the battery or to the light isolator switch.
2. The middle terminal connects to the positive terminal of the lamp (use the lamp’s red wire).
3. The negative terminal (marked with “-“ “earth” “3” etc) connects to the negative (black wire) of the lamp and to battery negative.
Problems: LEDs are unidirectional creatures, so if the lamp does not light up it is because the polarity at the lamp is reversed. Just swap the connections for the lamp only. If you have tried swapping wires or have bought one of my lamps with marked red and black wires and it is connected as shown...and you are still in the dark... something else is wrong, please, e-mail me.
E-mail me for a picture and schema if you need one. Thanks.
