2004 Amp draw when off

[dslksl]

What should the amps be when the truck is sitting there and off?

[WEF]

There will be a draw to the electronics but it's so small you won't see it on a regular amp meter. I think a Corvette is around 20 milliamps.

I think that you'll find that the number will be around 50 mA and will vary with cycling of OnStar (if equipped) and some modules don't shut down for a period of time.

I believe that GM doesn't actually consider a parasitic drain until 100 mA.

Hope this helps.

I see a 186 ma
Inline with a Fluke 87

Time to find out why.
Thanks for the input.

So is 100 ma the normal?

[dslksl]

I found a aftermarket amp that was not shuting off.
After I fixed that the amp draw went from 185 ma to 25 ma.


Thanks for all you input.
