Any Electrical Wizards Out There?
I just spent 4 days at a racetrack campground and our house battery drained each night. I just figured it was time for a new one but it charged up on the way home and held the charge for 2 days so far...

Well after literally tearing my RV apart I found the source of the drain. The refrigerator. It has a 1.4v drain on the system. The manual says its normal to draw 500 milliamps and should have little effect on the battery. So now I have to wonder how milliamps compares to volts and what condition is my refer. It works well, freezing stuff if we want, it's just problematic to light at times. This is usually caused by rust falling down the vent and landing on the sparker.
In retrospect I would advise against cheap Chinese DC clamp on ammeters. They are useless if they don't have the sensitivity to read less than 1 amp as mine is.
I charged my new battery off an on for a couple of days and it holds 'about' 12.9v. Not much better than the one it replaced but I have another that holds 12.8 that's a wet cell that I'll eventually install with a battery switch and forget about the refer draw.
Thanks for the help. I now know much more than I did and used the wait time to wax the rig. It should be ready for some worry free trips- after I put it back together. Now why oh why did they piggy back the refer to the lighting circuit?
