GS Battery died again

Is it this lead??

That lead connects direct to the battery. The connector up by the headstock referred to doesn't, instead it connects into the Canbus wizardry.

No!

I guess I found the problem. called to a friend of mine who is an expert on the CAN BUS system. First thing he asked was, what navigator do you have on the bike? I told that I have a garmin, he asked that is it a type of garmin which has a separate transformer on it. I told him yes there is a box between battery cable and plug for the navi. He told that here in Finland they had lot's of problems with taxi's where a certain type of garmin navi was installed, and all of those navigators where a type with transformer to decrease voltage from 12 volts to something lower. In my zumo 220 is a similar system. This system is poison for vehicles with CAN BUS system because even when you switch off eletricity completely from the circuit so this transformer still goes on, and even when the current is low so it leaves the CAN system activated and drains the battery,,,
So now I took off the navi fuse and tomorrow we'll se again that was this problem solved...

its a voltage regulator, some of the garmins use 3v or 5-8v, i imagine this would continue to drain the battery but am suprised that with the garmin removed (ie no load) it would drain it to flat that quickly?

Updates

Some updates for the problem.
took the whole garmin regulator away, and after 5 days there was still 12,8v in the battery. Sent an e-mail to garmin support and they told to wire the system directly to the battery. Their opinion was that will solve the problem keeping CAN alive even the power is switched off.
Anyway took the bike to the workshop today for sometimes poor cranking when hot, and mentioned also of the battery drain problem. Let's see in a couple of days what they say.

this will do the trick if you have the micro usb connector
