    Because there are so many variations it is impossible to give a definitive list of engines that would be suitable for this alternator.  You need to look at what you have and check it against our alternator mounting guide.  However we can say that these alternators are typically used on Detroit Diesel, Cummins, Caterpillar, and John Deere engines

  • Tech Tip

    To meet ABYC standards the wire to the battery must have circuit protection.  The level of circuit protection must be equal or less than the ampacity of the wire. To prevent accidental tripping the circuit protection should be a bit more than the rated output of the alternator, maybe 30% more would be appropriate 

    When sizing the output wire of this alternator the ampacity of the wire must at least meet the output of the alternator, see the Ampacity Tables for details.  Ideally though the wire size would be closed to the 3% Voltage drop rule, see the Voltage Drop Tables for details. A 5005 or 5191 fuse block would be appropriate.  Don't forget a cable cap for the output terminal which the ABYC requires for all exposed positive terminals.  A 4012 Cable Cap might be appropriate depending on the wire size you end up choosing.
