Bronco 351W alternator
Hi, my battery was dead today and I realized my alternator isn't giving my battery a charge. I have heard that alternators from some Mustangs will work as a replacement and will work better than those designed for the 351W. Any advise on what alternator to go with? Thank you for the help.

Bronco 351W alternator
The popular upgrade these days is the 3G.
Here is a list of vehicles that have the 3G alternator:
93-96 Tarus 3.0 V-6 (non SHO)
94-96 Mustang 3.8 V-6
94-95 Mustang 5.0
94-96 Thunderbird 3.8 V-6 (non SC)
95-96 Windstar 3.0 V-6 (most are 3.8's)
93-96 E/F series Trucks/Vans 4.9 L6*
96 Sable 3.0 V-6
94-96 Cougar 3.8 V-6
*Probably the best one if you can get it (should be easy to find, too) is
off the E/F series...this series uses a threaded top ear like the stocker on
the Mustang....E/F series with threaded ear uses metric bolt. ALSO, make
sure the E/F series is 130 Amps and NOT 95. For all other cars listed
above 130A is only option listed.
I run a late 80's externally regulated 130 amp alternator on mine (only because it was a freebie with my 5.0). It works great, keeps up with my winch and the headlights have never been brighter.

Bronco 351W alternator
Thanks for the advise. I decided to go with an original style alternator. They were $150 less than the newer style alternators and didn't require any wiring mods. 60 amps does seem kind of weak compared with the 130 amp new style but I don't really need the extra amps right now as I am not running any aux lights or a winch. I will probably go with a dual battery setup after I put my lights on, will the orig. alternator be sufficient to charge the dual batts?
