I've got a '99 windstar that doesn't seem to be charging the battery properly. I have a Haynes manual that gives a brief description of things to check. I checked the battery output and it checked out at 13V. The alternator output with the engine running was 13V also. This should be 14V+. The book also mentioned to check the fusible links in the wiring harness. I can't find them. Do you know where they are?

Also, the book tells how to check the voltage outputs from the alternator on a 3.0L but I've got the 3.8L. The 3.0L has a removable voltage regulator but the 3.8L doesn't. Additionally, the 3.0 has an A, I, & B terminal only but the 3.8 has the B terminal as well as a 3 pronged plug. So which is the A & I on the 3.8?

One last thing to check before I spend $200 on an alternator. What is the best way to check the wiring harness chargind circuit for shorts or bad grounds on this charging circuit?

 

If it is not charging then what you are thinking without giving any second thought go for the new one..It will not give you problem in future...so go for it
