Chrysler Repair: 05 chysler town & country stalling, intermittent problem, chysler

Question
Hi Roland
Back on 6/14/08 I asked (I have an 05 Chrysler T&C. While driving the van you will hear a "ding ding",the gages peg out, and the brake and ABS lights will come on then return to normal in a matter of seconds. Then after that occurring, when coming to a stop or accelerating from stop the van will stall.  You are able to restart van with no problem. Sometimes will notice that gauges will sweep when starting the van. took to dealer and they have advised me to change the battery. But problem still occurs. This is an intermittent problem.) Since then I have changed the battery. There is no check engine light so I can't get any codes from the computer. I have taken the van to the dealer and they can't find anything wrong. The dealer told me there was no fault codes, only that the battery had been disconnected, and had 20 starts. This was not accurate because I had one month from the time the battery was changed to the time the van stalled.  They had changed the PCM and FCM.  But the problem still continuos.  But only when the out side temp is over 70 degrees.  Just the other day the van would not start, and everything was dead. the van had no power. nothing worked. I noticed that the Acc. relay was clicking. then 15 min later the van started like there was nothing wrong.  When the van is acting up I will notice that when the cooling fans turn on the odometer will pulse. then stop when the fans turn off.
I have taken some video of the problem. If you would like to view then I could E-mail it to you.

Any help is greatly appreciated.
Thank you for your time

Answer
Hi Brian,
Thanks for the offer of the video, but I get the picture. It appears to me that you have a very basic problem with the electrical system that impacts almost everything, intermittently. Particularly the mention of guages and the warning lights and even the acc. relay clicking, along with the stalling, even though these are probably on different + circuits from the various fuses in the power distribution box. Usually we are told to check/replace the battery, forgetting about the other side of the electrical circuit that is necessary to operate everything: the return ground paths back to the - post clamp of the battery. I would suggest that you take a look at a couple of the main ground wire connections that originate from the - post clamp of the battery: specifically look at the fatest black wire on that clamp and follow it to where it attaches to a point on the engine just above the starter motor. Make sure that it is attached tightly. Then there is another fairly fat black wire that returns from several of the components that appear to be flaky that attaches to the body near the powertrain control module (engine computer) located on the left side inner fender surface of the engine compartment. Make sure that the eyelet on the wire and the place on the body where it attaches are shiny and then be sure to reattach the wire tightly at that point. There is a third ground in the engine compartment in the lower left front corner, below the headlight housing/near the corner of the radiator. See if you can find that fat black wire and be sure of its clean, firm attachment.
Finally, check that the black wire at the - post battery clamp are not corroded or loose in their attachment to the clamp.
Let me know if this does or doesn't correct the problem, please.
