battery drainage

[libertyc <libertyc@erols.com>]

Hello group  - I'm about to diagnose a severe battery drain problem and 
want to make sure that I am approaching it correctly.  If I attach an ohm 
meter in series between the + battery post and the + cable, I should see 
no reading (with car and accessories off). I do.  So, I am going to use 
the wiring diagram and disconnect circuits one at a time until I see no 
flow.  Then I will try to narrow it down until I find the culprit. Is 
this the correct method??
