Second alternator

Aug 13, 2004 1 Replies

Thank you all for the advise on engine braking. Is the second alternator a factory only option? What are the advantages and disadvantages of having a second alternator?


  1. Yes.....the ECM and wiring harness are different. Others have tried to add one, it's a MAJOR undertaking to the point of not doable.
  2. Well, faster charging and a higher capacity come to mind
  3. Another thing to F up and leave you stranded

Addendum...instead of asking PSD questions here and wading through answers from Windstar owners, why don't you go to

and visit the forums section? More info there on Ford diesels than you'll ever be able to read...
