Accessory outlet in topbox 2010 gl1800

[Twoup6]

I have had a USB outlet connected to the accessory outlet in the topbox powering a Sena SM10 and other devices until recently when I found power is no longer present. I have checked all fuses but no issues. Can anyone advise where this gets power from before I start stripping down the wiring harness to look for broken wires.

To the best of my knowledge, the first generation of the GL1800 (2001 - 2010) does not come with an accessory outlet in the topbox from the manufacturer. Unless, the Australian version is different than the American version, that accessory outlet is something that a previous owner installed. You will probably just have to follow the wiring to find out where it is connected to power.

Hi Mikeb, thanks for the reply. The accessory wiring is standard behind the cover in the lid. I have connected a usb outlet to this wiring.

Okay. I will have to go with what you know because I am not aware of an accessory socket option on the 2001 to 2017 Gold Wings.
I had to add accessory sockets on the 2003 I owned and now on the 2017 I recently bought.
Maybe the Australian Deluxe model comes with the accessory socket already installed.

I would pull the top inner lit out and start from there. The plug may have come off the USB plug. Use a tester on the plug and see if there is power. If not, then start working your way to the fuse panel. Also check the wires where they go from the lid to the back of the passenger seat. They have been know to pinch or get caught and get cut.

On my '09, I had to replace the harness that goes up the right side from under the seat to the trunk. My rear speakers weren't working, but I found a number of wires broken at the hinge for the top. Power runs up this harness to a plug in the lid for the lighted factory mirror (option). There are two plugs in there one for the rear spoiler light and one power plug.

Is the power plug a factory installed option or is it a plug that can be purchased and installed by the user? Does it plug into one of the power plugs under the trunk lid?

I know that there are a couple of ports under the lid, one that is powered on at all times and is used by the Vanity mirror and another that I have not used. I do not know what the other port is for.

Thanks again Mikeb. The USB outlet is one that I purchased and installed myself. I have connected this to the power outlet behind the lid cover where power is available at all times (with ignition off). It looks like I will need to check the wiring at the hinge to search for broken wires.

Thanks Twoup6, that clears things up a lot.

You most likely have it plugged into the red connector under the lid. That power is also used for the Remote Trunk lock. If the remote trunk lock is working properly, then there is still power there. It is most likely a bad connection at the red connector where you have the USB outlet plugged in. Maybe the connection is slightly oxidized and causing an open circuit to your USB outlet.

If the remote lock is not working, it appears that a fuse may be blown. Look at Fuse #22, Battery Fuse. The wiring is a possibility too.

Have just checked and when the remote lock button is pressed, the hazard lights flash but the locks do not activate. I will remove the lid liner again this afternoon and check wiring. Thanks for the heads up.

I have since removed the cover and the seat and disconnected the harness to find that there are three wires with no continuity. Red/yellow, white and yellow. I believe that the red/yellow is my problem but I will run three separate wires and confirm that this has fixed it.
