Green yellow refers to green with yellow stripes. Colour main tracer use brown main battery feed brown blue control box to ignition and lighting switch feed brown red compression ignition starting aid to switch. A good example of this is circuit 36 which is the alternator s output wire. The protective ground must be either green green yellow or bare copper. It is shown on page 12 of the 1981 evtm as being a yellow wire with white dots.
1 which identifies the main circuit part of the main circuit gauge of wire and color. A black dot can be used to suggest the injunction of two lines. A good example of this is circuit 36 which is the alternator s output wire. However certain colors have been adopted as local practice and are recommended. But since they did away with dots in 1986 on page 15 the 1986 evtm shows it as a yellow wire with white stripes. They show the diameter of each wire using a label placed at some point along side its drawn line 1 0 8. The us national electrical code only mandates white or grey for the neutral power conductor and bare copper green or green with yellow stripe for the protective ground. For example a wire marked gr would be green with a red stripe. For all other functions there are no legal requirements.

The protective ground must be either green green yellow or bare copper. Wiring code identification information wire code identification each wire shown in the diagrams contains a code fig. These can take some effort to locate on fold out map type diagram.
1 which identifies the main circuit part of the main circuit gauge of wire and color. The voltage across either hot wire with respect to the neutral wire is the same 120 volts. There should be a legend around the wiring diagram to inform you what each color means. Due to safety reasons the use of a 2 wire ungrounded system is discouraged. It is shown on page 12 of the 1981 evtm as being a yellow wire with white dots. Black is the default color and the wires in a 2 conductor cable with a ground wire are white and black. The color is shown as a two letter code which can be identified by referring to the wire color code chart fig. In the united states the national electrical code nec mandates electrical wiring color codes for the protective ground. Automotive wiring diagrams and electrical symbols.
