Recently my battery has been going dead if the car sits for a few days. I checked the current draw with the ignition off, with just the stock battery wire it draws 150 mA, and with my sub wire connected (which also has the alarm) draw is about 280 mA. Anyone know what the draw should be?
with EVERYTHING off, should be 0. put a self powered test light in series with your negative battery cable and start pulling fuses till that light goes out, had the same problem with my teggy. good luck. but to answer your original question its .2 but that will drain your battery quick
Current draw will never be 0, unless you disconnect the constant power for HU and clock.
However 150mA is a lot, [maybe a relay stuck on] and 280mA is way too much, could be a problem with alarm.
gen2crvtec is correct about pulling fuses until you find the circuit that is drawing the current, you obviously have a multimeter so you will not need a test light.
The draw will have to be on a constant power circuit, so start by pulling the “hot at all times” fuses.
The amp power lead should have 0 draw when system is off.
You say the amps power lead is also the alarms power, if so, disconnect it and connect it to a constant power under the dash, it should not be connected to the amps power cable.:stare:94
most computers & accesory electrical with pull 100ma or less but it will never be zero if you are pulling more than that when you hook your meter in series you have to wait for about ten minutes before you start to diagnose your problem (most oem computers have a sleep mode that doesnt begin until after the key has been turned off for awhile) Then start to pull fuses one at a time until your current drain slows down
sorry ill be more specific, i waited untill my computer was off when i searched for mine, and a test light made it easier, instead of looking back for numbers i just looked for that light to go out
