2006 Ford F-350 Super Duty Question: Blue smoke and battery drain

 

Question

Visitor, Diesel, Milwaukee, WI, April 17, 2010, 10:38

My truck has 100K on it. Recently I noticed quite a bit of blue/white smoke from the tail pipe along with a reduction in power. I had the turbo replaced for the third time. Power back and smoke reduced greatly but some smoke still persists. Also, once every month or two the truck won't turn over after sitting for 2-3 days. Within the last year I have put two Diehard Gold 895 CA batteries and a brand new alternator. I had a shop hook up a meter between the neutral and the battery. For the first 30 minutes or so the truck draws approximately 30 milliamps. I've been told this is normal. However, after 30-45 minutes the meter shows a sudden jump to 80-84 milliamps. It's as if someone just threw a switch.

    30 milliamps is great, 80-84 should NOT kill your Battery in 3 days, that would take 300 or more. How ever, maybe that surge gets much higher over night, so that needs to be discovered and resolved. What kind of shape is your starter in, maybe it is drawing too much ? What is the Starter Draw? Very important! I used to work at Ford Dealerships and Diesels are really tough on a Starter.

    I would have a really thorough electrical inspection done, including voltage drops of your grounds, your Battery Cables etc. Also load test your Battery with a real Carbon Pile. Just because it is new does not mean it is good, I got a batch of bad batteries and 5 or more were useless. I had to test them all and replace them.
