Coach Battery

The Coach battery is in a box below the passenger seat. 
It is only accessible from beneath the vehicle.

You have to loosen the bolts then slide out the cover.
Place a trolley jack or other support under the cover before removing the cover plate, and do NOT get any part of you underneath it.

Be VERY careful with the terminal connections, as it is possibe or short these to earth when removing or replacing the battery.

You should only use a deep-cycle battery to power the coach (a starter battery will get damaged quite easily if constantly discharged).
Due to the difficult location of the coach battery, you should fir a sealed unit which requires almost no maintenance.
