Need a Quick answer from some of you electrical Guru's...Acceptable power drain?
hey I've got a pretty small battery on my car and it has worked fine for about 6 months but just recently the battery has been degcharging itself after I shut down the car...I wanna say it the battery I tested the drain using my multimeter and its about 50-60 milliamps or it was .05 or .06 amps....now this happened after my room fuse blew I never did find out why it blew in the first place though...I've looked through the FSM and the Haynes manual and cannot find acceptable drain figures...

Former Moderator. RIP Icemark.
50 to 60 mA is perfectly fine. I have seen a couple base FCs that were as low as 40 mA with nothing active, but that is pretty rare.
Above 70 mA is where I start worrying.
60 mA will take about two weeks to three weeks to drain a stock rated battery down.
Since it sounds like you are within range on draw, check to see if you have a bad cell in the battery. The battery should be at 12.6 volts with everything off. If it is under 12.0 volts you may have a bad cell internally in the battery.
Car batteries are sorta like those pace makers or hearing aids that have multiple 1.5 volt batteries stacked together to get the right voltage. Sometimes after accidents or major impacts one of the cells will short across, limiting the output at idle and draw (but generally not while charging).
