Hima electrical circuit

[DZR]

I am preparing the 2018's Himalayan of my daughter (silk road project 2022).

1 What type of long life battery advised to replace Royal Enfield part?

2 I am going to install a double USB socket (2*2A), a handlebar GPS and fog lights (Halogen). All the 3 devices to be connected to the battery output.
To help, I am loocking for a simple electric diagram and also ideally a tutorial (video).

Thanks in advance for help

Recommended?
I say Motobatt - MBTX9U
Had this brand for last 16 years on 3 different bikes. On my Kawasaki 750 lasted 7 years.
Apparently quite a tight fit, but does.

replacing Himmy battery

I just replaced the battery with a Motobatt MBTX9U, hopefully won't have to do it again for a good few years, what a pain in the arse job.

Hi Bluestrom,

Thanks for your post . I am not sure whether this battery is available in France but I should find something good as well.

I ran one trailer wire cable with 5 individual cables inside and a separate thick earth from battery (switched with a relay and fuse) to front of bike on to the Left side of front tank guard behind the Royal Enfield badge.
I used a 5 pin connector to run my devices. Used two pins for my LED auxiliary light, one for my GPS (Garmin Zumo) and one for my dual USB charger. So I still have one spare circuit.
Hope this helps.
PS I don’t recommend halogen aux lights.

The OP did say fog lights, something most Aussies don't have much experience of using!
Some cars like my Subaru have them, and additional tail lights too, but I have never needed to use them, and I live atop Mt Lofty and often start out in the clouds!
But I remember the proper Pea Soupers from my time in Scotland. could be quite nasty, particularly if it was freezing at the same time!

Hi Petespace1,
I noted with interest your solution.
The plan for me will be to connect : a double USB socket (2*2A), a handlebar GPS (Garlmin Zumo XT) and fog lights (LEDand not halogen) .
Why my choice for fog light: because it delivers a wide lighting and in the rather near vicinity front of the motorbike, what is missing from the main lighting. In addition there are several location along the road silk where fog or equivalent will be met.

I quickly draw two circuits for you. Circuit 1 is more elegant but a bit lazy, pay attention to the current flowing!

There is a second USB charger in there. Those things can fail and nav equipment runs out battery quickly! Racing to the next city and trying to find the bike shop when the battery symbol turns red sucks. Speaking from experience!
Modern chargers draw only few uA and can be wired directly to the battery. I have this one hidden safe and dry under the seat just in case.




Circuit 1:
Obviously this puts more load on existing circuits but that is okay imo.
The Head light has 10A fuse and the H4 high beam draws 5A. I would not want to add more than 3A to that, so the real power consumption of the fog lights can't exceed 36W. You can fit stronger fuses but don't overload the wires and connectors they are only rated 10A.
The horn has a 10A fuse but is rarely active, this circuit can actually take some more. Horn needs 5A???, the USB needs 25W (2A) max and the GPS maybe 15W (1.5A). There might even be room for heated grips with a 15A fuse.






Circuit 2:
Much more complicated but safer and can even supply Halogen.



My favorite is Nr.1 really nice and simple

Thanks JulianK,
Your drawing and comments appreciated. I am still not decided wich way I will follow.
For the moment? I am still awaiting the delivery of GPS and the fog light will be ordered soon.
