link not found

thanks for the link but it keeps saying page not found.. is it only the front running lights that are supposed to stay on? cause my rear ones have always been on. im sure it is a wiring issue but thats weird that they were always wired wrong. lol

I would test the voltage going to the bulb contacts. Also could be a single element bulb instead of dual. It is easy to put the wrong bulb in the socket, they look about the same except for the dual contacts on the bottom of the bulb.

The wiring harness for the rear fender is on the right side of the bike under the side cover. If I remember correctly there is a bullet connector for each light. It would be easy for just one to come loose. If you have voltage at the fender connector and the bulb socket, it has to be the bulb or the way it fits in the socket.

If it used to work as a running light and now does not then you need to locate the aftermarket item that is causing them to be on as running lights. I'd bet that where your problem lies. As stated above they were not designed to used as running lights when it left the Honda factory.

still nothing...

:dontknow:i traced all the wires and checked all the connections in every light... taking each light off and checking the inside connections also.. still the same result.. one lights up and the othere doesnt.... blinkers still work.. im assuming that the one that lights up is the actual problem but everything looks as it should:dontknow::banghead::banghead:

Ridgeville,

Look at the bulbs in your rear turn signals.

Are they both dual filament bulbs?

If they are, then they are there because of a previous owner
doing a modification to the lights.

If they are dual filament bulbs, try replacing that left rear bulb
with a new one.

There are two ways that the dual filament bulb can be wired
for use as a running light.
First and easiest is to wire the dim filament to the taillight
circuit. In this case, the dim filament would not go out when
the turn signal started blinking, so it wouldf blink
'BRIGHT-dim-BRIGHT-dim

The second way is better and easier for following traffic to notice.
You would run extra wires from inside the headlight shell all
the way to the rear turn signals and connect the rear dim
filaments to the front running lights. Now the dim filament
would go out on the side that had the turn signal blinking,
so it would blink BRIGHT-out-BRIGHT-out

Finally, there is a mod where you glue a ring of LEDs
to the lens of the rear turn signals and get power for
the leds from the taillight and steal the ground for the
LEDs thru the filament of the turnsignal bulb.

You haven't told anyone which of these mods is present in your bike.
You need to give us this info if you expect any of us to be able
to help you.

In the meantime, here is some info to help you out.

Under the right side cover is a bundle of wiring connectors.
The colors that you would be mainly looking for are

Green-- ground
Brown-- taillight and license light
orange left turn
LightBlue right turn
green with yellow stripe brake

The wires go thru the rear fender via a rubber grommet
which prevents the metal of the fender from cuttting the
insulation of the wires.

The wires run along the inside of the fender near
the inner fender support and can sometimes be pinched
between the two.

If you run shorter than stock rear shock absorbers
and wider than stock rear tires, it is not impossible for the
rear tire to rub against the wires and break the
insulation.

The bullet connectors in the wiring bundle can sometimes
slip out of their receptacles.
