I want to add a 12V power socket (i.e. a cigarette lighter socket) to my XM-2000.
Do you think I should:
(a) connect directly to one of the batteries in the string
(b) connect to the DC to DC convertor (which I assume is the black box that sits where a battery for a gas scooter would have been)
(c) something else?
I know that (a) will create an unequal load on my batteries - but then my PowerCheq's should compensate for that, right? This is the most trivial approach.
I'm leaning towards (b) - I just have to figure out which wire does what (shouldn't be too hard ;-) )
Do you think I should add an additional fuse? If so then am I right in thinking that one should always put the fuse on the negative wire? (If so, why?)
