Can anyone post a photo of an unmolested Bayou 220 battery compartment?

I have a Bayou w/ butchered electronics, and I can't tell what goes where. Both battery wires are black, so I can't even tell which one is positive and negative.

Thanks in advance.

 

hot/(red-positive) wire ought to go to the solenoid then on to the starter. the other one, negative, goes to ground.

 

That's the thing... there is no red wire. They're all black (all 3 or 4 of them.)

I just want to make sure nothing's missing, before I begin tracing them all.
