Satnav power problems

[MarkW]

Hi folks.

Is there any reason why my satnav would work off the 12v supply in my car but not off the connector I wired onto the bike battery? The screen flickers quite dimly and then it switches off (the battery in the satnav has long since been incapable of powering the unit). It's a 2006 ZZR600 with a 12v battery, and I wired a Digitek Moto Charge USB into it.

Cheers!

Maybe your bike battery isn't 100% anymore so is struggling to power the bike and sat nav? Try checking your connections to the battery make sure they're tight could be something simple.

Good luck!

Hmm... This is odd.

My satnav (a Becker BE Z101) has the cradle hard-wired into the 12v circuit in my XC90, and it works fine when it's in its cradle. If I pull the USB cable out of the back of the cradle and stick it in the USB socket on the side of the satnav, it still works fine. But, if I connect it to the cigarette lighter socket with another USB cable it doesn't work, doing the same thing it does on the bike (flickering display and then powering off).

So, either the cradle is wired into something that provides a different current to the cigarette lighter socket (seems unlikely) or there is something specific about the cable connecting the cradle to the power source. As far as I remember it was just a bog standard a USB cable.

Any thoughts people?

Sounds like you need to test your socket on your bike and not your sat nav.

OK - quick update, because I know you'll all be anxious to know how I'm getting on

I chased the cable in the car from the back of the satnav cradle to where it joins the car wiring. I thought the guy who did it had spliced the USB cable into the switched 12v circuit, but what he's done is splice in a cigarette lighter socket and then plug the original 12v charging cable into that. The plug on the charger takes the 12v feed down to 5v.

So, I'm going to look for a 12v USB to 5v mini USB adapter (if such a thing exists) and then I should be sorted.

You'll be after one of these then mate plus the adapter.

Problem solved: I bought a new satnav that'll run off the 12v USB socket I fitted. It fits in my tank bag perfectly, and is tons better than my 5 year old Becker. Sorted!
