Do you own a volt meter?

Has any testing been performed?

How long must the vehicle sit before the batteries go dead?

Hello I'm Chris a Ford Employee and Certified Engine/Transmission Specialist.

Thanks for asking your question. I am eager to get your vehicle back up and running correct. Be aware it is difficult to fix concerns associated with noises and smells over the net, but I will do my best. Diagrams are often copied from other websites. I am here to help you out for a small fee far less than a dealership and easier on the wallet, so if this information is of aid PLEASE PRESS ACCEPT and help me out financially by paying the small fee (which you selected). Please reply if further discussion is needed.


Ok you have verified you have a parasitic draw which is discharging the batteries. You will need to follow this test which will require the use of the volt meter and removeing fuses to see which circuit is drawing power.

Basically,I put the ammeter inline between the neg cable and the negative post. I should have an exessive draw ( 50 MA). Then i remove one fuse at a time to find the one with the high draw.
It would be very nice if the image could be printed bigger

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
