Looking for someone who would know how much current (in mA) a 1999 Toyota
Avalon draws when it is turned off.
Background: The battery in the Avalon keeps going dead (newly purchased 60
month battery one-year ago) so I recharge and it is fine for a day or maybe
a week, then dead again. Took the car to a Les Schwab store and had them
check the battery and charging system; both ok. Put a amp meter between the
positive terminal of the battery and the cable and the car is drawing 15mA.
Trying to find out if this is normal or too high.
Further checking of the individual fuses show the radio fuse is drawing ~3mA
and the dome light fuse is drawing ~4.5mA. Pulled all the dome lights (8 in
all) but still drawing current. Not sure what else is on that circuit; I
have a the factory manual but not the separate electrical manual (extra
$80).
Any help would be greatly appreciated.
Thanks,
Tim |

If you are going to park for a week or more, turn the auto headlights to the
off position. It should draw a little less with the headlights in the off
position. 15 mA is a little high but not grossly so. Some aftermarket
audio, remote start, and security systems draw all the time.

Just guessing here, check lights in the glove box and trunk and make sure
they go off when shut.

15mA is only 2.52 Amp hour in a week. This is not enough to kill a
100 Amp hour battery. It is probably close to the self discharge
rate. Your problem is probably elsewhere, an intermittent switch? >> Stay informed about: Phantom Load on Avalon |

You should also check your mirror lights if you have one. I once gave a jump
start to a woman who's mirror light had drained her battery. >> Stay informed about: Phantom Load on Avalon |

I can confirm that two ECUs, a CAT1 alarm and immobiliser and a stereo
in my car draw approx 15-20mA. However on a good battery that will last
indefinitely (has lasted a month on mine, 62A battery, without going
flat) but with my old battery that *appeared* OK it wouldnt last two
days.
