Battery Connection Help Options

[AvalonFal]

I've been having problems with the battery draining over a couple of days of non-use, so I'm intending to replace the PO's battery cables (a few splices in the current ones) and go from there. PO relocated battery to the rear trunk & that's OK. However, I came across this situation:

- Engine off, key out.
- (+) battery cable disconnected at battery
- (-) battery cable still connected

I measured across the disconnected (+) cable to the connected (-) cable & got a voltage of around .6 - .75 volts. Is this normal to have voltage across a disconnected (+) cable??

Car starts fine when battery is charged, but, as I said, battery loses juice after being idle for a couple of days.

Thanks everyone for the electrical info.

Getting closer, but I've hit a dead end. I've isolated the current draw to the larger red wire at the fuse panel that runs from the battery (+) post. When I pull this wire off the panel, the draw disappears. Of course, a lot of things also disappear, like interior and dash lights and many other accessories.

So, where do I go from here??? Is this wire 1 continuous feed from the battery to the fuse panel with no other connections in between? If so, do I need to run a whole new wire from the battery through the tunnel to the panel?
