E320 will not start, dies when jumped
If we jump it, it will not go very far before it dies. I am thinking this might be related to the alternator? Is there a chance that it is the voltage regulator? If so, it's worth the $60 chance to replace it and see how it goes. Is there any better way for me to diagnose this?
Charge the battery first before you check voltage with the eng. running.
If the battery is fully charged then it should start without jumping it.
If you have the same voltage at the battery with and without engine running then your alternator is not charging, replacing the regulator only might get it to charge.
