Negative Cable

Replacing House Batteries. In a 2005 American Eagle, when I disconnect the Negative Cable that has two other cables on the post. I found out one cable has a draw on it, even though I have tripped all breakers as we all as the main battery switch. I do have a magnum power manager and inverter.

I would like to know if anyone has had this and knows what the draw is from. I'm hope someone can help me with my issue, before I start using my test light and pulling fuses to locate what circuit it is.

Inverters have a slight draw and a pretty good spark when connecting them.

Save some time and remove the inverter positive cable and see if the draw goes away on that negetive cable. The inverter positive cable should be the one that goes to a 300+- amp fuse near the battery.

Solar panel. Find and pull the fuse.

LP gas and CO detectors bypass the battery disconnect. So does the base power for the multiplex controller under the bed - it has a separate power line direct to battery positive. It uses that power to operate the battery disconnect switch, for one thing!

Negative Cables

Thanks to all for the help. I found it was my Inverter causing my issue.
