2006 F650GS Starter motor and battery needed in Ulaanbaatar ASAP!
 

The voltage reading is around 14.4V. I think heat probably killed the previous battery due to the stupid placement next to the oil tank and air box. Both of which get pretty hot on a warm day and there's little cooling to the battery. Using a tank bag doesn't help. Hopefully that's all it is. As you can tell I know little about electrics but that flow chart is really good and I'm pretty sure that was all done yesterday

Now as i remember I know at least two separate cases happened to friends to pretty much same bike/model range where bike batteries have died in Mongolia.

In first case it was not sure what was liquid level of battery when bike left from Finland but some distance after Irkuts coming back from Mongolia battery was dead dry and dead.

In other case battery died near Gobi desert.

I am not expert with BMW and GS650 bikes but definately for me sounds like it would be good to periodically check liquid level if you dont have AMG or gel-type battery.

First battery that died in Kyrgyzstan was gel type. Second battery was cheap Chinese acid battery but the liquid levels were fine when it died and had only done 5000km. It was extremely hot though

I have a F650 GS 2006 in UB
 

We can talk about it if you are still in need?

Please contact me.

Pieter
