WTF, XT 660za, battery under fuel tank
 

Well; as the manual says; should you need to charge the battery; Contact a Yamaha dealer, smooth...

Maybe I should be graceful I can fuel it myself...

Since I plan to use my bike as a job-commuter the whole Winter (here in Stockholm Sweden that means below freezing point), and also generally; I would like to be able to charge the battery myself;

I plan to connect wires to the battery and have them ending under the saddle or similar easy accessable Place, for charging and (hopefully never necessary) jump-starting (i.e. Cable of 10mm2).

Anyone know how "tricky" it is to remove the tank to access the battery? - tricky/sensitive connections for the fuel - hose and level sensor.

You should wish Yamaha had made this kind of "feature" original whith the bike.

Tank removal is fairly easy - the second time....

Remove the two side panels (the ones the indicators are attached to), two allen head screws each. Careful of the large rubber washers on the lower pins, they'll make a brake for freedom (I've put some duck tape around the pins so they stay in place)

Remove the side 'scoops', theses are the protection panels on the side of the tank, not forgetting that they are attached at the front of the rad too.

Remove the plastic supports from under the tank that the scoops are connected to (you can manage without removing these - but it's easier if you take them off, only three screws each),

Remove the two long bolts from behind the scoops,

Remove the seat, then the fixing plate at the end of the tank (where the tool kit lives)

Lift the tank up, put your hand under and remove the retaining clip from the fuel connector.

Remove the two electrical connectors, and the overflow,

The fiddly bit, squeeze the sides of the fuel line connector together, the connector will come away from the tank easily. If it's not easy, you haven't squeezed enough!

Best to do this with an empty tank.... obviously!

Lift the tank away and put it on a blanket, or something else soft, be gentle - you don't want to destroy the fuel pump!

See.... easy.

Reassembly is just the reverse of taking it off.

Second time it really is much easier.

thanks a lot! - I strongly Believe this will be very helpful. - otherwise I will be back crying...

My suggestion would be to connect a battery maintenance system to your battery so then you just plug and unplug the device. I would start with a new battery and Yuasa is generally the best. Then I have used Accumate in the past and then I discovered the Yamaha branded one which is made by CTEK and I now have about 4 and my bike batteries now last even 5 years, cos I always connect one when I am not using the bike. Er well bikes, cos I have several!! Have fun.

You do not need to remove the tank to access the battery connections on the ZA model and connect up a charging port and/or accessories. You only need to remove the tank to remove/replace the battery.
