2007 cold starting electronic issue

I have a GPS and Gerbings hard wired to the battery. Occasionally, when it is very cold, I crank the bike and it is as though the battery got disconnected (my clock zeroes and so does my trip meter). It occurred a few times. Is it just the battery connection or is it something else? I have yet to fiddle too much with the battery as it is very cold and I don't have a garage.. Thanks for all the help!

 

I have to put a battery tender on mine in the winter Dani, or bring the batt inside over nite, its a pain but it seems to be the cold weather draining the battery.
If I let my bike sit for 2 days in this weather it will not start.

 

The battery on these things is just enough to get the job done, a little age and cold weather is all it takes to take it down.

 

The electronic systems operate on + or - 1 volt. It does not take much for failure.

Most of the cause in the winter time is a black greaselike coating that accumulates on the surface of the connections.
The connection may look very clean but when taken apart you will see that coating that is preventing the electrons from making a connection. It is acid so don't get it on your skin or clothes. Needs to be cleaned off.

THE PROOF.

You have seen a car that will not start, but..... The horn AND headlights work! It is just that that black greaselike coating is preventing the starter from working. Just cleaning the terminals will almost always start the car.

 

Thanks for the input all. I ride every day during the week. I don't have a garage and can't afford to take the battery in and out. Has anyone tried upgrading the battery to something stronger? I do notice a big difference compared to my previous FZ6 that never ever had any issues.

 

Seems weird. I've never had a problem & never used a battery tender. My GPS, hotgrips, HID's, ground effect led's & iPhone charger are all routed to a Centech aux fuse box under the seat that only powers up with the ignition. I don't hardwire anything to the battery. But if they're all powered off I'd think it'd be ok.

Have u tried removing the other wires from your battery to see if it'l last overnight? How old is the battery? Mine is stock '07 with not one problem thus far.

 

The battery lasts...it doesn't give me too much problems starting, even in 21 degrees (though, I do need to crank it a bit)
My issue that it zeroes the trip odometer and clock, both of which are annoying. Similar to what I would see if disconnecting and reconnecting the battery. Anyway, I'll try to take it a part and see if I have a loose connection.

 

I think you are on to something. This makes sense and I suspect this is what is happening. I need to see if I just remove the GPS if this happens again. It doesn't happen all the time and I kind of like leaving the GPS on it, but it is annoying because I use the trip odometer to calculate fuel range/mileage and am sick of recalibrating the clock each time.

 

Update: got a new yuasa st1300 battery and all problems solved! No issues no matter how cold.
