battery draw?

Alright yall quick question.

I've got a 2005 f250 6.0.
I'm having some kind of battery draw issue I believe.

With key on engine off I'm reading around 11 volts, after glowplugs are done and I crank it up It drops to around 8 volts.
Also, the ficm was just repaired and it's reading 48 volts pretty consistently.

Just went to o'Reillys this morning and both batteries and the alternator checked good.
Any ideas?

Clint.

Did they unhook both batteries completely and test them individually? Common problem is one battery is good and the other is bad but if they are tested together.... They test good. Since you have 11 volts with engine off, I'd say one of the batteries are getting weak.

Yeah they did. He said one tested at "good" at 98% and the other tested "good" at 80%.

If you batteries are dropping to 8 volts... I'd say the batteries (at least one) is no good. Have them checked by someone else. What are the volts after the truck is running?

After the truck is running it climbs back up around 14. I'm gonna take the truck back over there and have them pull both batteries out and put them on their load test machine.
Also, if it shows one is good and the other is bad, how could I go about getting them to replace both under warranty? Is that possible? I'd rather not just replace one.

I've had the same problem before, one bad & one good. Just show them your owners Manuel. It should say you need to replace both at the same time IIRC. Most autoparts personnel know that diesels require both need replaced at the same time.

I'm going thru something similar. I unplugged my GPCM and things went back right... so I'm replacing that, and with some great advice here, I'll be replacing the glow plugs as well. Maybe you're having the same problem...

Lets see.. if I replace: the EGR cooler, the oil cooler, the heads, the head gaskets, the head bolts, the coolant filtering system, the injectors, the turbo, the alternator, the FICM, the GPCM... THEN... will I have a DEPENDABLE truck??

80% aint good in my world, plus you are over working your alternator maintaining the draw.

And technically the "amps" are more important than the volts.

I agree heavy.
And sting, I read your thread I'm hoping that's not it.

You need to find and fix the draw. A long term draw will eventually kill good batteries and the alternator. The alternator was never intended to be a full time battery charger it only puts out a few amps and as mentioned amps are more important than volts.

The alt is supposed to go on and off for short periods of time and just maintain the state of charge of the batteries not be chargeing all the time.
