Amp Draw

Thank you Zora.
I hooked up my multimeter inline with the negative cable. When I plug it in, the system wakes up and reads about 630m/amps. (my meter is set to 2000 DC A m/amps) I am assuming that is "six hundred thirty" m/amps. After a few minutes it drops to 005 to 006. No decimals.
Again, I assume that is fifty to sixty milliamps. Is this correct?

OK... I might have to go a slightly different route with this.
I have a brand new battery. was unplugged for a few days till I had time to mess with it.
Checked the volts with battery unplugged, was reading 12.72.
Hooked up battery for a day or two, ran the vehicle, sat for a day, checked volts again, was reading 12.88 to 12.9.
Is this normal? Could my system be overcharging? Checking volts with engine running reads 14.75 ish UGH...
Failed to mention that that last reading was with the engine cold. As it warmed up the voltage dropped to 14.35 14.33.

Yes readings are with a handheld meter. I think I might have found the problem.
The vehicle does have an aftermarket radio in it, nothing fancy. It came with the burb.
Earlier today I went and put my meter inline with the battery again and had a higher m/amp reading. I was getting around 150-152. That was not showing up on earlier tests.
Started pulling fuses and when I got to the radio one, m/amps went down to what I was getting before... 005 to 006. I pulled that fuse out and left it out for now. No other problems as far as this thread goes. Not sure where this is going to take me but hopefully Ive narrowed it down.

Haven't chimed in in a few days. Radio is still unplugged and all looks good so far. Haven't had much time to mess with it but I think this whole time the radio was draining my battery.
Weird thing is that this radio has been in the burb since we bought it. Wasn't till about 2 maybe 3 years ago I started having these problems. Go figure...

I've always been glad that resellers offer harness adapters. I used one in my 'burb. I have an FCC license and experience in electronics, but the adapter harnesses make it a no brainer.
