Meter reading parasitic draw that is not pulling down the battery.

yobenny · Nov 25, 2024

One pic showing checking amps on the negative post, it's reading a 3.3 amp draw.
I forgot to disconnect the battery and left it for two days, came back realized what
I did, checked the battery, it's a half volt lower than it was.
How is that possible?
Shouldn't the battery be drained after two days with that draw on it?
Thanks for any help fellas.

Maybe that draw was before stuff like modules hadn't gone to "sleep"?

Have you tried cranking the truck yet?

All the modules are disconnected and all the lights inside are out, tripped the doors, it's asleep.
I took the amps reading right after I checked the battery voltage in disbelief that it is still charged, and there is the draw. I just don't get it.

A shop that looked at it said the E & B modules are fried, must have been lightning strike they said.
Nope it was not that I was standing right beside it.
They said scrap it, I said nope bought the new modules but afraid to put them in and fry them too because of this 3.3 amp draw on this that I cannot figure out. So no, I haven't tried to crank it yet.

I would recommend that this issue be kept in one thread. I'm seeing multiple threads and the answers and info is going to be all over the place.

I keep making new posts because nobody is giving any answers.

Maybe if your thoughts and test results were in one thread, it would be easier to digest and respond. Lots of good people on here with varied experiences. Ultimately up to you, though, it's a <somewhat> free country.
