Title: Amps
Post by: Vladi on November 02, 2007, 05:29:01 PM

I've measured how many amps the car uses with everything off (engine, etc.) and it turned out 0.86A.
Is that normal? Did anyone measure this?
I also measured my VW Golf it read 0.51A so i'm not far by much...

How did you measure the current?  You have to measure it inline (break the circuit and the multimeter will complete it) you can't measure current with one lead on the + and one on the -.

800 milliamps sounds kind of high with the key off IMO

Yes, i took the - off the battery and i connected the multimeter between the battery - and the chassis -.

.04 amps if its more than that then its to high (also, connect it and wait about 15 minutes and then check it, sometimes the ECU will hold voltage in it capasitors made for voltage spike protection).

.25A is still kinda high, .25ma is about right for our cars.

Do you have any car alarm??.Might be one of the problems,and even like that 0.25 means 250 mA ,it's an old model?,should be somewhere near 0.10,if not the only thing that could eat some power it's the cd player or the OBD because has a clock.
