2002 Ford Thunderbird Question: something draining battery,hooked up to meter and can't find source

Answer 1
you will have to perform a battery draw test by hooking up a meter in series between the negative battery cable and the battery terminal,then pull fuses one at a time until you see a drop in amperage.And wait 45 minutes after you hook up your meter to the vehicle to allow the modules to go to "sleep". -

Thanks I think they have done this or at least some of this. The owner of the shop says he fixed this problem on other cars but it can take as long as a week or more. Does this sound correct? -
Comment 2
It is possible for it to take a week or longer if the concern is intermittent.If there is a constant draw on the system it should not take very long to find.I wish you luck,and keep us posted! -
Comment 3
Thanks again. I'm told the problem is intermittent. What would be a fair cost to repair? -
Comment 4
Greg's is absolutely right! try another shop,sometimes the tech can get flustered with the problem.It's not because he/she is a bad tech,you just get overwhelmed sometimes and need a break.Another shop might find it right away,just be up front with the info about the previous diag. Information is a good thing for a tech.Best of luck,and keep us posted! -
Answer 2
seek a diag from another shop.int issues are hard to find and very hard to est. ask ? when you arrive at repair shop and only ok a diag fee of approx 1 to 2 hrs labor. sounds like you got alot of good advise from double. good luck -
