I have a 1994 Ram 1500 5.2 automatic. My truck has been great, till a few months ago. It is having a charging problem at idle in gear. I have replaced the alternator, the battery, replaced the cable ends, replaced the alternator again, checked all the wires, checked the fuseable link, I cleared all the codes, replaced the alternator again, getting ready to replace the battery again. Still I have a problem at idle in gear, it drops down to 10.5 volts. Anyone that has something else to try it would be appreciated. I really need my truck back.
