my 3b has someone’s restoration harness in it, but someone added a lot of other little things making circuits hard to follow, and now my brake lights are not working.
The harness looks like a quality braided covering one, i have seen the schematics, but they do not show what color wire goes to what. Does one exist with colors, were they consistent at all? Edited by bkwudz - 19 Nov. 2017 at 11:22am |

Sorry, my 3B has messed with enough that when I tried to trace down why my rear lights didn't work I found 3 different colors of wires heading back there. I think I would first check out the brake light switch. Connect the 2 wires and if the lights are on you have the answer.

Paul,
My harness was decomposed to the point I couldn't see any color. Many wires were already replaced with modern generic wire (all the same color - so I had to trace them). I have a new harness in a box yet to be installed. Here is a partial on color: Using the Vintage Wiring of Maine manual, they identify Green W/T from stop light switch to upper harness. Left and right tail lights have Green G/T and Red W/T (I requested an inclusion of a turn signal which may affect color- I haven't gotten into it yet). |

thanks Rus, that is helpful.
I believe I have a harness from VWOM, I would guess I have a short somewhere, as now I notice when I put the lights on, it trips that breaker on the switch half the time. Maybe the switch is bad too.

My light switch breaker was kicking off all the time. Turned out that I had the bulb in my tail light in slightly skeewhompus and the bulb was doing the shorting out. Took me a while to run this down, but other than time it didn't cost me anything to fix.

Is that a new technical term? |

There's a reason it's called Ol' Unreliable

Yes, check the light switch. I had two go bad on my 3B few years ago, and they were new replacements. I can't remember the brand however. One switch was shorting out enough to stall the engine every time I pulled the switch on. |

Here's a post from Jeeproger about a known problem and repair for some of the faulty new repop headlight switches.
