Tip & How-To about Acura CL
Turn off all lights and accessories and remove ignition key
disconect negative battery terminal
connect an amp meter in series between the negative terminal and negative batery post(have red positive lead go to terminal and black negative lead go to battery post)
now ur meter should read less the .5amp or less the 500 milliamp
some vehicle may have slightly more if they have alot of electronics but .5 amps is good rule of thumb
also remember that the computer systems on many newer vehicles may take up to 40 minutes to go into sleep mode.
so u may want to leave the meter on and come back later to see if it has gone down if it is excessive on initial reading
if u still have excessive draw on the battery start removing and replacing fuses 1 at a time until the reading on the meter drops to within specification.
at that point u know u have found your problem circuit
