She has started up every time,
Charging starts out at 14.5 volts then levels off to 13.8 volts after running/driving for about 15 minutes.


Did a current check with everything off, and meter shows 30 milliamps.
I think this is low considering the four items drawing current, but no major current draw.
Charger does shut off when battery full.

 

Received the Wi-Fi OBD tool, as Gorn suggested.
Selected the free application for iPhone and works pretty good.
Only problem, was unit left plugged in for about 15 minutes and it had gotten hot.
I will take and check it later.

Camaro worked great yesterday, started a dozen times in my journey of errands.
however, once charging dropped to 13.6 volts, starts after this, voltmeter only indicated 13.8 volts.
Since larger battery, current draw is 'spread' over the volume available than compared to a smaller battery capacity.

 

It's been a week sitting with no charger. Voltmeter indicated 12.4, during cranking showed 11.6.
Started right up. Charging started out at 14.5, then leveled off to 13.6 volts in the 20 miles driven.

 

I forget have you done a draw test yet? You should not see much of a difference for sitting a week.

I just order one of these , it should take the guess work out of diagnosing electronics. It has a current flow adapter also. Ton of info on youtube about them.

Thanks, Gorn, I did a quiescent current draw in Post 11 and found 30 milliamperes. and no major draw over an amp.
As far as starter current, I have an inductive meter, but no assistant at this time.
