Second Battery

[PinkRacer]

In our '99 Yukon, there are 2 batteries, but one has no wires whatsoever running to it, and it's a Delco battery. Why would that be there like that?

[ZZebes]

its supposed to be hooked up as an Aux battery. Go see the dealer

does the yukon have a plow or a lot of accesories?

Nope, stock SLT as far as I can see. Had a 7way trailer plug, but only the basic lights were hooked up (signals, brakes, tail lights, ground, reverse/aux). There are no wires anywhere near this battery...so I'm puzzled, because of course it'd be toast now from not being hooked up and sitting in the cold.
