I have a 07 jeep wrangler(jk) 3.8L in the shop that seems to keep burning up alternators. Charging at 14.5+ at all times causes them to get hot and burn up. I've tried a new pcm, new wire from alt to battery, new battery terminals, ground cable straight to alternator housing, checked all other grounds. I read the tipm also controls the charging system? Any advice would be appreciated
