High Output Alternator by API – 120 amps
This alternator is ignition protected in accordance with SAE J1171
This alternator from API (the same firm who has been supplying our very successful 55 amp alternator) is rated at 120 amps, 70 amps at a nominal engine speed of 1800 RPM. It is internally regulated with a single output terminal, similar to the OEM Motorola and our 55 amp alternator. Like the 55 amp version, the 120 amp alternator is quite forgiving of passing through “OFF” on the battery master switch.
We have retained the 3/8″ belt groove as our standard configuration, which in most cases makes it possible to use the same 26” belt as used on our API 55 amp alternator (Product number: IGLM_09_34.1). Please note that the correct O.E.M. alternator support arms measure 9 – 1/8” in a straight line from the center of the lower mounting bolt hole to the very top of the slot. Earlier O.E.M support arms only measure 8 ½” in this dimension and will not have adequate adjustment to properly tension 26” belts. Refer to product number OVEL_03_222 if you need to replace your support arm.
NOTE: Except for warranty exchange, this electrical item is not returnable.
