Topic: Blinker insanity! 76 Honda CB500T

[Meet The Twins]

Replaced the flasher relay, the handle bar controls, and the rear blinkers. Now when I activate the blinkers the rear blinkers flash but the front blinker just goes out.

-Front blinkers work as marker lights.
-Rear blinkers DO NOT light up as marker lights.
-When rear blinkers are activated they will flash but the front blinker will go out.
-Bulbs are fine

The PO had cut the front blinker wires and stuffed them into the headlight shell.

I have two orange wires and two blue wires. I dont know if both blue wires go to the right side and both orange to the left or if one blue and one orange on each side.

Of course the wiring diagram shows a green wire to each side with a blue on the right and a orange on the left.

Any Ideas?
Thanks guys!

Hi dont know if i can help as i am not familiar with indicators acting as running lights  , as here in the uk we don't have them, usually orange is for one side & blue is for the other , have you checked your earths are good? maybe someone else will chime in and help you better ? cheers mick.

Your diagram does not show any provision for the front marker lights. Orange is left, blue is right, green is ground. The marker light wires should have a white stripe. I will assume for now that you have swapped in the 550/4 style switch with 7 wires, for the 3 wire switch shown in the diagram. It connects as follows:

Orange - left turn
Orange/white - left marker
Blue - right turn
Blue/white - right marker
Brown/white - tail light circuit
Brown/blue - idiot buzzer
Gray - flasher

Hope that helps.

Happy trails.

I think there is a white tracer on the marker lights (or a very short piece of tube?)
 The solid colour is the indicator. Sounds like the green ground wires are not connected (they my be black with green tube on them)

Check all grounds and look for rust on/in the signals. Mine was an unforgiving mistress...

Thanks for all the tips guys! I tried your suggestions but nothing helped. You see, I cant find a wiring diagram that matches my CB500T. I have a 9 wire left hand control. NONE of the diagrams I have found show a 9 wire left hand control.

Prehaps it is a PO modification? Sounds like an option.

The CB500T wiring diagram shows a 9 wire left hand control.

On my Kawasaki I have two gray and two blue wires. One each for each side. On mine the blue wires went to two red wires for running lights and the greys went to two different colors can't remember them just now. Is you bike equipped with emergency flashers as well?  Follow the wires out of the bucket and see if one color goes to one side or if both colors go to both sides. Try both the orange and the blue to your running light power source (probably two wires the same color with power on when ignition is turned on) Whichever color produces the brighter light is the signal wire. Hook the other to the running lights. Then turn on one blinker and try the other wire until you get it blinking. Then switch to the other side. I couldn't find a wiring diagram so used this procedure and mine now work. If once you get them all working they blink slow just go to a heavy duty flasher unit.

Check a real Honda owners manual or shop manual (same but bigger) wiring diagram, the others are worse than useless.
I think you have connected the marker wires to the signals, these lights should be on in low beam only and go off on the side the signal should flash on. The rear signals have no marker function (in most markets including North America and the UK). Check the wire colors going to your rear signal lamps, the front signal lamps will have exactly the same colors. Wiping the wires with alcohol or varsol will let you see the colors better, they get coated with grunge and all look greyish after a while. I'm pretty sure you need solid light blue and solid orange color wires for the signals, the marker wires have a thin white stripe as well.
