Parasitic battery draw?

[gauge_half_inch]

And just a side note,are you testing the positive or negative side? It should be tested on the positive terminal. Also you can use the meter without breaking connection of power if you use a clip style lead for the terminal end and the standard for the post side. Lossen the terminal and clip the lead to it place the other standard lest in the center of the post and slide the terminal up over it. It should not break vonnection and reset everything.

Correct me if I am wrong. The ROOM fuse is for the white/red wire and is hot at all times. It provides power through a 10 amp fuse to all the equipment that has memory such as ECU, radio and dash clock. It is there for all the interior lights including the cargo light. If you pull that fuse, there should not be any pull on the battery from the rest of the electrical system. Good luck.

Freakin car wouldn't start again this morning! Gonna test again tonight and see if I missed something. Would very short trips have anything to do with it? I pretty much only drive to work and the grocery store, both of which are less than 5 minutes away.

Unhook neg cable at night until you find the prob.

I had a similar issue with my 02 E350 turned out I had a bad cell in the battery.I kept thinking I had a some small amp draw. Jus a thought---

I'm assuming its draining down overnight then? Maybe tonight when you get home, just unhook the battery and in the morning hook it back up and see if it will crank. It does sound like it could be the battery not holding a charge. If its dead in the morning after being unhooked all night, you'll know its the battery. If its not, you'll know its the car killing it.

Batteries also perform best at about 80 degreesF. If its 100 degrees out or 45 degrees out it makes a difference too, and will exploit a weakness that you can brush off and neglect in warmer months.

Could be. Thanks for the heads up

Will definitely try it out

Yeah, seems like it has this problem in the mornings when it's colder

I vote for the battery being bad. If you hook up your ammeter in series with the positive side and after about 10 minutes you have no more than a couple hundredths/thousands(can't remember which is the safe zone) of an amp then your battery is loosing it's charge. Also don't disconnect the ammeter after you get your reading or you'll disrupt connection and regaining the connection again to recheck will have a false reading, you need to leave it hooked up.

cody,run it by autozone & get a free battery & alternator report.

Think I'm gonna run to autozone and just tell them to give me a new battery!
Been keeping a close eye on it, checking volts before I start it up, when it's running and after I shut it off and everything seems fine. Go out this morning, check the battery and it's at 11.4xx volts and the car wouldn't start!

Car/battery has been fine the past few weeks. Battery was dead again the other morning, fine again for a few days, now dead again this moring. Just gonna replace the battery now and go from there

damn my blue car has developed one of these!!!!

Yeah man, it sucks! Only power I can figure is being drawn overnight is the door popper, but it's not drawing that much. Battery is being charged/tested at autozone right now so I'm hoping the battery is fudged!

I like this style amp gauge, you pull the fuse and plug in its place , helps isolate current draw . I have seen them low as $14 in harbour freight
