1992 Nissan Maxima battery drainage when car is not running

Hi Jimmy,

you can test for draw on battery by using either a test light or a digital volt meter.

To test, make sure everything is off, if has light underhood remove bulb, make sure all door etc. are closed, then remove either the Positive or Negative Battery Cable. Next connect the the Test Light or DVM between the Battery Terminal and the Cable. If using test light if light turns on then you have a draw the brightness of the light indicated significants of draw. If light is fully lit the you have a 12 volt draw.
If dimly light you have about a 1 - 2 volt draw. Of course if using DVM with know amount of draw.

Then leaving light ot meter connected start pulling fuses. Pull One at a Time, checking light or meter each time. When light goes off or meter read 0 then you have found the circuit the draw is on.

From the should be able to determine cause.
