Amp draw with ignition ON? (1 Viewer)

[Everlong]

Chasing an electrical issue here. Can someone tell me what is the amp draw measuring at the battery with ignition On? No fans, lights etc. Just the ignition.
Thanks

Lots of computers and motors being fed during and after key-on...your 10A fused handheld meter isn't going to be able to handle that current. I've seen it shoot past 20-odd amps on one for a quick second before the fuse popped.

It is a lot whatever it is. I can get 30 min with it on acc and the battery is a harder start. Leaving it for a week at the airport gets me to 12.2v

Big assumption here is a healthy battery. Get it load tested - especially if it's new - new means you have 0 history with it, not that it's good.

From healthy charge to 12.2VDC over a week is a small draw. The dome light pulls enough to draw the batt down past that in a few hours. What's the draw with key off? Should be ~.05A (50mA depending on your meter reading) at rest after the key has been off more than 2mins.
