Am I able to access a Switched Live from the pic below, please? Do the numbers help? I'm pretty sure I have done previously but I can't remember where. I sold the bike last year and removed accessories but now I have it back. I need a Switched Live for sat nav lead and usb lead.  |

Behind #5 is a 5 amp acc fuse. It powers the two wires inside the #2 tube.

Thanks. So, should I swop the ring terminals on the lead for bullet terminals and plug in to the two female terminals in the no 2 black sleeve? What about my usb lead? |

If I've got the sat nav sorted for No.2, I still need advice for a Switched Live for my usb lead.....

Parallel off the #2 and use it for both. A USB draws very little.

Should run USB un-switched. Allows for phone charging or other accessories Without key & headlamp ON  |

USB for charging jump start / compressor will draw 5-10A. What does nav draw? Careful! |

You should run a relay to power up everything you add on. Hot off the battery to a 10A inline fuse to the relay and then output to each hook up you need to use. the 5A as a trip for the relay only

Thanks but I don't think I need a Relay. I don't use accessories such as heated vests or heated grips or extra lights etc. I just need a Switched Live for sat nav ( now sorted) and a way of attaching my usb lead instead of straight to the battery. The USB lead will be for occasional use of a Gopro or using phone for Google Maps if I don't have my Sat nav. |

That is the proper way and practically fool proof. Keeps the added circuits sorted & Makes future modifications much easier to implement. Also makes a return to stock straight forward |

Also makes a return to stock straight forward To be honest, I more or less dismissed the relay suggestion as my electrical knowledge is not great. I wouldn't know what to buy, what all the terminals mean and where to put it. |

Just to clarify...
The two ACC terminals are Green and something else (possibly Green and Red). I can't quite see.
My Sat nav leads are red and black.
Do I plug in Sat nav RED to one of the acc terminals in particular and attach the Sat nav BLACK to an EARTH on the frame?
If so, what is the second ACC terminal for?

Here's part of the wiring diagram for an early Tourer. Looks like the acc terminal is green/orange (or maybe red). Grounds appear to be green. Clymer has easier to read diagrams than Honda.  |

If there's ever any doubt about a terminal you plan to connect to, get out a voltmeter and test those terminals before connecting anything!

Yes. Remember, it is a 5 amp service.
I used my 5A acc wire to operate a relay to a tiny circuit board. That board has hookups that go straight to the battery with a 20A fuse inline  |

I can see that, in the diagram, there's one red and green lead going back to the fuse box and then on go the ignition switch so that must be the Switched Live. So, do I plug in my Sat nav RED lead to that and find an earth for my Sat nav BLACK lead? I also have a solid Green ACC terminal lead as well. What would that be? Also, someone has replaced the ACC 5amp fuse with a 3amp. |

I can now answer my own question following a "Search".
The Green is EARTH.
The Red/Green is LIVE.
If I utilise those two terminals my Sat nav is up and running with the 3amp fuse in the fuse box.
USB probably straight to battery with inline fuse.
