Approximately how much current is "normal" or nominal for a remote start alarm and bypass module to draw when at rest sitting there disarmed or armed?
I am seeing 0.05 Amps or 50mA when at rest on that circuit. That's 0.6 Watts.
(That is at rest. When the car is "awake" it draws 630mA on that circuit without the Alarm/RS and Bypass. When the car is "awake" and the Alarm/RS is connected then the draw is 680mA.)
The battery was old and very likely the problem, so I replaced it. I just want to make absolutely sure that there isn't a drain the Alarm/RS and Bypass wiring.
Thank you VERY much for sharing your experience / knowledge!

I think I have seen from other posts that 50mA or less is normal.
Can someone with more experience please confirm that when you have a chance?
I tried searching before I posted, but I saw a lot of troubleshooting steps that didn't mention the target current draw. I dug some more while I was waiting for the car systems to go back to sleep and found mention of 50mA or less a couple times.

This post helped me a lot: https://www.the12volt.com/installbay/forum_posts.asp?tid=57883
I'm linking it here if someone else is searching through the forms for battery drain alarm remote start current milliamp type keywords so they don't have the same needle and the haystack.

I have always considered anything under .06 as normal. Usually there's little draw difference between armed or disarmed, with the execption of spikes from light flash and chirps when changing.

That 630 milliamp draw seems very very high to me, the alarm/r/s combo armed I would expect 35-59 milliamp extra.
