USB outlet

Postby drafter55 » Thu Sep 01, 2016 1:57 pm



I recently bought a used 2007 GL1800 and feels great to be riding again after a 5 year. Also great to see this web site so thanks to all that contribute. I installed a dual USB outlet in the left side fairing pocket. It plugs into the wiring so it is almost goof proof. Don't ask about the one hole too large and the other hole in the wrong position. :-)
I found the USB charges my MP3 player as advertised. However if I try to plug in the Aux plug while charging, all I get is clicking. As soon as I unplug the USB cord, the MP3 plays just fine through.

I have verified correct polarity and all that. Is there a fix for this?

Thanks

Can you provide a bit more info on the MP3 player. It may be tht while charging it can't be played, possibly? have you used this MP3 player in your car for example with no issues while charging? I currently use my IPhone SE connected to power and the AUX plug with no issues....2008-HPNA

If you unplug the MP3 player from the power does the noise go away ? If so you need to isolate the usb power from the bike power or possibly use a noise filter. If it is still there when you are not connected to the bike power than it is the cruise control noise. Not a lot you can do about that one.

If it is the bike power that is causing the problem than add the iso power supply. I have added a 1.5A 12V to 5V isolated power supply to the bike. I power my bluetooth transmitter and my Garmin Virb camera off of it. I just gutted the electronics out of one of those cheap dual usb adapter for the usb socks. Works great only noise I on the audio is a very very small amount from the cruise control. By using the dual socks I can power or charge an additional device while powering my bluetooth transmitter.

A lot of the time the MP3 player (or phone, or whatever) doesn't isolate the audio ground from the power ground, and you can end up with nasty ground loops when running the music player from a charger.

Try a ground loop isolator, it will fix this sort of problem.
