As an example, the HID system needs a good 7amps @12-13V to ignite and get warm, thereafter only 3amps. Together with the above mentioned stuff, this may cause problems with charging the battery, thus meaning no electric start!
PS: I assume you've got a larger capacity battery installed (stock one is only 4Ah)?
Hi Tony - yes, I believe that was basically the problem Neil had in Dos Sertoes...
The battery in my bike is a Yuasa YTZ7S - so presumably 7 amp hours?*
Sticking a meter on my battery, it seems to drop to about 12.3V when everything is switched on (Nav, fan and HID) - but goes up to about 12.8V if you raise the revs... you probably know more than me, but the guys at Trail Tech seemed to think their stator would be fine to run the HID and the fan, and keep the battery topped up?
A few posts back Spick mentioned he runs an HID with the stock battery (admittedly not a fan too) - but hopefully there won't be too many times I'm going to need both (unless I'm stuck all night in the dunes!)
I had a look, it says 6Ah...
