I have an '05 f350 diesel. For a very long time if I let my truck sit for a 4-5 days or longer my truck will not start from low battery. I do have after market things like radio w/amps etc. air bags, viper alarm, etc. But I have disconnected them and it still happens. Ford said its probably my aftermarket stuff and they stop there. so I have just put up with it for years now. Yesterday I used an amp meter and found on stock thicker wire coming off the battery that is drawing about .4 amps with the truck off. I started pulling out fuses and when I pulled the one for the "cluster" it dropped to a low ".0 "something.
Called Ford and I was told that it is normal for the cluster to pull .5 amps.
Seems high to me and I dont see anything else drawing much of anything to make my truck go unstartable in a few days. Is .5 (half an amp!) or even .4 normal draw for the cluster when the truck is off? Can anyone measure theres for me? It is the slightly smaller thick wire off the drivers side battery.
One note; at one time I brought it in for this reason about a year and a half ago they said I had bad batteries then they checked the alternator and said it was bad, they replace all but I still have the same problem.
