How do I access the wiring at the front of the bike?

Post by BRYuma43 »



I'm tracking down why my tail light isn't working. Thanks to this forum, I think I've got it narrowed down to no power on the brown wire past the fuse block . My question is, how do I best access this wire between the front of the bike and the connector under the seat? Should I remove the false tank? The fairing? I've got a 83 aspencade.

Take the false tank off. There are 2 screws on each side in the front. Take them out and throw them away. 2 bolts at the rear of the tank where the seat sits. Lift the false tank off.

So you're saying when I re-install the false tank, just use the two bolts at the rear by the seat? I can tell one of the front ones is missing already so I only have one more to go to get it off :D

Sorry but I've just gotta poke my nose into your problem with a question...
The brown wire you mention...is is solid brown or does it have a tracer color and where is it located?
Do the park lamps work up front?

The 10 amp parking fuse..with the key on is there volts on both sides of it.?

The plug for the tail lamps (I think) is under the seat.The brown wire is for the park lamp.

No, please poke away!

I have brake lights but no tail lights (or the light on the volt meter- I believe it's the same circuit). Headlight and all turn signals work. Digital displays all work. I ran a jumper between the fuse block and the tail light (solid brown wire) and got the tail lights to work. There is no power to the brown wire before or after the connector under the seat, so I'm looking to trouble shoot the front section of the brown wire. I'm thinking now that I might just run a new wire from the fuse to the tail light rather than try to get at the existing wire in front of the connector under the seat. It ties into a harness that I can't follow without digging - that's where my initial question comes from.

Virgil - also, I don't get a tail light in "On" or "park". From reading, there is power from two sources (10amp fuse and 5 amp fuse)? I don't care much about the "park" functionality, but does the brown wire provide power for both? Is there another problem I need to troubleshoot since the lights don't work in either key position?

Thanks

I'll go over the schematic and post the results with this info in the morning.

Ok.Lets look at this.
10 amp fuse marked "tail".is there volts on each half with the key on.
It is the switched power feeding most everything.
If it's ok,look for this plug from the right switch cluster.Take note of the jumper on the plug.
It connects the power from the tail fuse (brown/blue) to the brown/white wire feeding the lighting circuit.
This jumper is the most likely problem.

Yes, there is power at both sides of the fuse...

Ah, I was confused about the brown/blue wire I saw last night when flipping over the fuse block. I was expecting it to be brown/white at the fuse block, then transitioning to brown somewhere down the line all the way back to the tail light.

Yup.the color code change is at the switch cluster plug.I think it was a universal harness and perhaps in Euro it may go to a switch to shut off the lights.Something we
cant have here.
I've never looked for that plug on mine so I can't speculate on where it is.
Keep us posted and take pictures if you find the problem.Its impossible to post a schematic of this circuit..sorry for the screen shots.The whole schematic looks a mess and difficult to follow on my phone.
I hope this helps sort this out.

Thanks!

Where did you get the schematic? I have a service manual for GL1100's thru 1982 and I don't see a 1983 aspencade version on the website here.

Also, I think I know the response I'll get, but what are your thoughts on using a fuse tap on the 10amp fuse and running a wire directly to the tail light rather than trying to dig into harnesses and such? (see attached pic). It wouldn't fix the mini bulb that lights the volt meter,
but at least it gets me riding.

Use the tap if you need to.Unplug the fuse and turn on the key.You want to put the tap on the side that does not have volts.Its the load side and the fuse will protect the wiring.
To get moving it's fine to do this.Its a temporary bypass.
You can tie to the brown or brown/white wire..

Thanks Virgil. I'm itching to ride this thing. I'll dig into the harness down the road. I know what to look for now. I'll probably replace the fuse block too.
