parasitic drain experts..., read this Options

[njccmd2002]

i have been busting my back trying to find a parasitic drain. i think i found what drains my battery.

i have 2 options. the aftermarket pioneer radio or the aftermarket alarm. funny.

anyone has had an aftermarket radio do this. its a pioneer.

i have both disconnected and seems too be no more drain. of course i have to see which one is the culprit....


stay tuned

If you have a good multimeter you can measure the amperage via it's fuse to see how much power the item itself is drawing, a good number for total parasitic draw is about 50ma on a car with a bunch of stuff like you have, it's probably the alarm though, especially if it's a fancier one. My 00 Celica has a steady 30ma draw when sitting off, it's got a factory alarm with features comparable to aftermarket alarms (intrusion, glass break sensor, keyless entry). The radio will have some key off draw to keep settings alive, but if it's got a high draw it could be the bluetooth module inside not going to sleep. I've seen that happen with Honda factory sound systems.
