Re: Battery Problems
Are they putting a timed load on the batteries? I don't know what some of the shops are using to check batteries nowdays. Ford (2 shops) claimed my starting batteries were fine when I had problems a few years back. Took it to a friend who has a shop and after we checked all the connections, we dropped both starting batteries and found one bad. We used an old carbon pile load tester and it showed the battery bad quickly. What Ford was using is beyond me but in my case I really doubt they ever separated and tested each battery on its own.
When batteries go flat, a trickle charger isn't enough and you should hit them with at least 10 amps for a day. Check to see if one or both gets hot or gives off any smell and if so stop the charge.
If the batteries test out OK, Have the shop look at all the connections points on both ends. On my 06, the alterator hot wire runs to the fuse block so you really need to look over any place there is a connection point on the negative and positive leads. Even the battery post leads can be bad, so you need to look it over closely.
Also make sure you have not left something on in the van or see if there if there an extra draw off something that might be failing like a short. An amp gauge is a pretty handy meter to have for trouble shooting. I had an alternator that cause a problem for me years ago. It still charged but pulled about a amp or so at rest. Killed the battery within a week. If you don't have a house battery system, then anything in the cab that's 12vdc can be the problem.
