Most of the time, there’s a high-amperage fuse or fusible link between the alternator’s battery terminal and the battery. Also, there are usually low-amperage fuses in series with the alternator’s sense terminal and ignition terminal. Like any fuse, the primary alternator fuse acts as a circuit protection device.
Do you need a fuse from alternator to battery?
Fuses are installed to protect wires from an overload, meaning that the draw (amps) from the load (appliance) exceeds the capacity of the wire (the size or gauge). Under this premise, the only way an alternator needs a fuse is if either the battery or the alternator itself experiences a dead short.
How long do fusible links last?
6. All Fusible Links shall be replaced once a year. The Links shall be replaced sooner during annual inspection if the conditions in (4) exist. The Fusible alloy that is used in the manufacturing of the Fusible Links undergoes a phenomenon known as Creep or Cold flow.
What kind of alternator does Prestolite use?
New Leece-NevilleIdlePro™ series alternators provide the industry-best output at low enginespeeds through an innovative brushed, dual internal fan design.
Is the 120 amp fuse for the alternator PAL?
It must’ve been brief, because I didn’t see/hear/feel a spark. So the 120 amp fuse for the alternator is a PAL type fuse, and it is a bit of a PIA to remove. I’m a mechanic, so it wasn’t very difficult for me, just time consuming. However if you were an average Joe who somehow made the same mistake, you’d almost certainly be going to a shop.
