Parasitic draw test / question / and multimeter

Pardon me for what may seem a dumb question or questions, or ones with obvious answers, but I suffer from this anxiety bullshit and the meds I'm on don't always work, so ....

1.) I've a 1990 Dodge Ram 50 2.4L base model. Is there any kind of amperage draw if I merely leave the key in the ignition overnight? I would think not, but I'm far from expert; and,


2.) I just want to make sure I have this correct. I seem to have a "parasitic [ amperage ] draw" on my truck from somewhere. A YouTube video on the subject said I might need to be able to read as far down as milli-amps to find the culprit. Can someone please just look at this and tell me if it looks like this multi-meter will do the job for me? https://www.amazon.com/Genssi-Profes...ale+multimeter


THANK you for any responses, and your understanding

That looks like a nice meter, does a lot of stuff much more than a Multi-meter.

It looked "nice" to me also, and the price is decent. Thanks for your help, LSR Mike.
