hello all,I stubbled across this TC lock/unlock forum while looking for the answer to this problem, I have read all the patch fixes, etc. and this fix seemed like the most promising. I have a 2002 Ram 2500 Cummins, auto trans, about 120,000 miles. I cleaned all the terminals then removed the 140 amp Alternator fuse, the TC issue seems to go away as described with the alternator out of the equation. Then I removed the factory alternator and had it tested, on their machine everything passes, I then asked for the details of the test and noticed the AC Ripple Voltage was 0.2v, which I know is higher than the 0.1v ideal per this thread. I then asked to test a brand new alternator prior to purchasing it to see if its AC voltage was lower and it tested at 0.3v, so I did not purchase it and am basically stuck at square one. Any Ideas?Thank you,Josh
