About this part

This alternator replaces the Ford unit on the 7.3L Power Stroke trucks. It is rated at 105 amps and built new. The catalog note lists it for ambulance builds with a single alternator system, which tells you the bracket and output match that arrangement. Charging problems on these trucks often show up as dim lights, slow cranking and repeated dead batteries.

Fitment notes

7798810N is listed for the 2000 Ford F250 Super Duty and 1999 F350 Super Duty with the 7.3L V8. The note mentions ambulance and single alternator systems, so dual alternator trucks need a different part. Check the fitment table or send your VIN.
