Use the Bally Color Code Here's a copy of oldReno's post on the color code. There is no need to memorize this code, just print it out, so it's handy. Bally schematics use numbers, not colors on their prints, so using this number code will make things much easier to troubleshoot. "Bally color code. The pneumonics are "Red blooded yankee girls wear brown or black garters." 1 Red 2. Blue 3. Yellow 4. Green 5. White 6. Brown 7. Orange 8. Black 9. Grey (gray if you prefer) 0. Means it is a solid wire, and there is no trace. Solid wires often carry voltage other than signals. 10 means a red wire with no trace. 20 is a blue wire with no trace, generally your 6V light feed. 30 (yellow) is your 'common' wire. 50 is part of the 120V system. 70 is a solid orange, which is your 50V feed, or source. 80 is another part of your 120V. All wires have minimally 2 digits. If it's solid, there is a 0 at end. If it has a trace, the 2nd digit is not a zero. The body color is the first digit, and the trace is always the 2nd digit. A dash ( - ) after the wire denotes its next re-use. For example, on a schematic a 93-1 wire is not the same wire as a plain 93. So be cautious, often Bally had to use the same color wire for different circuits, although I don't know that they used any solid wire ( 0 ) as a duplicate. Expect a solid wire to remain true." |
