Waiting on Ford for my new Alternator to be installed and have a new battery so hopeful that will resolve the issue. And we can get back on the road. Ford only lists one alternator for the 2018 Expedition, part# JL1Z10346A. They don’t the output for it. BBB indicates it is rated at 250 amps; PA Performance states you can get 230 amps. Pretty big alternator but can anyone confirm? or do we agree with the above ratings?
