06 Cummins Voltage through the ROOF!!
I was driving along today when I got a check gauges light in my 06. The voltage was low so being 7 years old and 100k+ I figured that the alternator had finally gone out. So I pulled into a autozone that had one in stock opened the hood to find the passenger battery had blown the top off the water. Battery acid was everywhere. I replaced the battery and fired it up again. the new battery started spitting acid out the top. Got out a volt meter and found out the alternator was pushing 20v into the battery. So I pulled the alternator. Had it checked was told that the alternator was functioning perfectly. Put it back on and now it was showing 22v going into the battery. So I pulled it again. Same results alternator functioning normally. All the while the voltage in the cab is still showing at 10v. Called Dodge gave them my symptoms. Was told that the ECM is more than likely the problem and the only way to fix it is to replace it. $1800 for the unit and 2 hours of labor to fix it. I don't have $2000 plus at the moment and this is my only vehicle. Is there any way to fix it ASAP. I have to work on Sunday night. ALSO is there anything other than the ECM or the alternator that would cause this?

check your connections. the alt charges the pass side battery and the ecm reads off of the driver side battery so if the cable that connects the two dosnt have a good connection it will over charge the pass side battery. seen exactly what your talking about happen before.
