I have an amp in a car. I thight it may be sucking too much current in off
mode.
its pulling 40 ma. in off. Anyone know typical current draws of typical
amps?
My car often sits for long periods of time. Even months. Thats 1 AHr in 24
hours. Too much.

My first knee-jerk response is...if you can put together this muchI have an amp in a car. I thight it may be sucking too much current in off mode.

After owning my Datsun 280Z for 26 years, I think I know what to do, how to doYou are not taking care of your car properly. Car batteries are designed to
be drained from starting the car and recharged up at a minimum on a weekly
basis. Otherwise you need to put the car on a trickle charger.
40mA is in reality virtually nothing. Most modern car computers draw 50ma
give or take when the car is off, add the car stereo/clock and easily you
have 100ma.
You are looking at a car battery with more than 1000 AMPS available current.
Granted 500 amps or so is required to start the car. The cars battery will
slowly have as much or more internal leakage current than total standby
draw of what is in your car. 40mA is well within tolerance for a device.
If it really sits for months at a time, you have bigger concerns than the
battery, like dry seals, sitting dirty oil, dry rot in the tires, etc.
Suggest you check into the proper preparations for keeping a car in storage
or non-driven condition, Or get out to the car, start it up once a week, and
drive it at least 30 minutes continously to get everything al the way hot,
charged up, and lubricated.

After owning my Datsun 280Z for 26 years, I think I know what to do, how
to do
it, and when I want or need to do it.
I had a Ford once that had a leaky brake light switch that of only 100 ma.
could discharge a less than perfect battery fairly fast. After I fixed the
switch, it worked fine.
Does anyone know how much a typical power amp draws, because
I need to know if I need to order a new one.
Thank you
