Question for Ford techs about testing draw
I recently had my truck in the Ford dealer because my battery would not last longer than a week or so without running the truck. They diagnosed it as the fuel pump relay energizing at times throughout the night. They replaced the whole fuse block assembly as the fuel pump relay is one of several not replaceable.
My question is if this relay is not replaceable how were they able to disable it to pinpoint it was the problem?

you would be amazed at some of the pinpoint tests that are in the workshop manual. most likely found it through a pinpoint test and disconecting certain connectors untill the draw was within spec. also alot of time what you will see writtin and what the service adivisor tells you is not even close to the whole story especially if its warranty.

have you ever heard of the problem I am having? They replaced the entire fuse box but I think i still have a draw on my battery, i think. It has gone from 12.32v after shutoff to 12.35v and the latest reading was 12.34v about 5 hours after shutdown. I suspect overnight it will drop even more.

that will work. here is what you do. make sure your doors are closed and all aftermarket accessories unpluged and everything else turned off. disconect negative battery cable. with the meter on the 10A scale (and the leads in the right place on the meter)put one lead to the negative post and one lead to the negative cable(dont worry if it reads negative you can switch the leads if it really bothers you) let it sit for at least half an hour untill all the modules power down and you will have your draw reading.
i usually use a pair of vise grips lightly clamped on the negative post and some aligator clips to hold the leads on.

ya the guys in my other thread have told me all about how to do it. Problem is first time I tried it blew the fuse in my meter, so JackandJanet walked me thru how to use jumper cables to keep the circuit alive and prevent the fuse from blowing.
If my battery is any lower I will attempt to test draw myself.
