The Iveco Truck 24V Charging Platform
Iveco truck applications in this alternator family use a 24V charging system with 90A alternators. The alternator numbering spans the 5801 series (5801315646, 5801541381), the 5802 series (5802122270, 5802122271), the VG-series number VG1560090010, and a group of other OEM and brand numbers (5041143977, A4TA0591, 8600399, 16SI, 18SI), all referring to the same charging-system family for the Iveco truck platform.
It is critical to verify the output voltage, current rating and pulley type on your old alternator: this unit is rated at 24V 90A with a 10PK pulley. Alternators with a different output voltage, current rating, pulley configuration or mounting pattern are not interchangeable with this unit. The 10PK pulley and the 5801315646 family number are key identification points for this unit, so check the pulley belt type and the OE numbers stamped on your old alternator carefully.
Confirm the mounting bracket, terminal positions and connector configuration against your original alternator before ordering. Always cross-check the OE numbers stamped on your old unit, including the 5801315646 family, before placing an order.

Compatibility and Cross Reference
According to the original product page, this alternator fits truck applications in the Iveco 5801 series alternator family. The original page does not publish a detailed fitment table, so do not rely on the application name alone for fitment validation; always compare the original part number, mounting holes, pulley type and connector configuration before ordering.
| Brand | Application | Notes |
|---|---|---|
| Iveco | Truck, 5801 series family | Verify 24V 90A 10PK |
Multiple OEM and cross numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 5801315646 serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the output voltage and current rating on your old alternator: confirm it is a 24V 90A unit. Other ratings are not interchangeable.
2. Check the pulley belt type on your old alternator: confirm it is a 10PK pulley. Alternators with a different pulley configuration are not interchangeable.
3. Confirm the application is an Iveco truck in the 5801 series family. Other applications may use different alternator assemblies.
4. Compare the mounting bracket, terminal positions and connector configuration with your original alternator, and match OE numbers including the 5801315646 family.
5. Weight cross-check: genuine matching unit weighs approximately 7.9 kg net; significant weight difference indicates wrong assembly.

FAQ
Q: Which vehicles does this alternator fit?
A: It fits truck applications in the Iveco 5801 series alternator family. Confirm your exact model, year and OE number before ordering, and check that your old alternator is a 24V 90A 10PK unit.
Q: My old alternator shows number 5802122271 or 5041143977, will 5801315646 work?
A: Yes. These numbers belong to the same alternator family for the Iveco truck platform, differing only by production revision and market specification. It serves as a direct replacement.
Q: What do FAT5801315646 and VG1560090010 mean?
A: FAT5801315646 is the FAT-prefixed variant of the main number 5801315646, and VG1560090010 is the Iveco VG-series number for this alternator. Both refer to the same charging-system family with 5801315646 as the main part number.
Q: What are 16SI and 18SI?
A: 16SI and 18SI are Delco Remy SI-series alternator family identifiers listed in the original part-number area; they are kept here as reference identifiers for the same alternator family.
Q: What is the correct charging voltage after installation?
A: A healthy 24V charging system should regulate at approximately 27-29V at the battery terminals with the engine running. If the voltage is out of range, check the alternator, regulator and wiring before further testing.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, incorrect wiring, water ingress, short circuit or physical damage.
In Practice
The original product page does not publish a specific installation method or torque data for this alternator. The following section therefore uses the general 24V truck alternator installation standard, with reference to the common installation practice for Iveco truck alternators and after-sales maintenance experience from the auto repair industry; before installation, compare the specific torque values with the corresponding Iveco service manual.
Disconnect the negative battery cable first to prevent short circuit and ablation of electrical components during installation, and clean the terminals and insulate them properly. Park the truck on a flat and hard surface, apply the parking brake, and chock the wheels. Remove the fan shroud and any drive-belt covers as required to expose the alternator installation position. Clean the alternator mounting surfaces and the tensioner bracket fixing holes, and treat rust and oil stains with rust remover. Confirm the new alternator is the 24V 90A 10PK type, and inspect that the rotor turns freely, the pulley fits the 10PK belt correctly, and the housing has no cracks.
Fit the alternator onto the mounting bracket, align the fixing holes and insert the bolts by hand as pre-tightening, then tighten with a torque wrench following the diagonal tightening principle; for 24V truck alternators, a typical reference torque for the main mounting bolts is 25-35 N.m and for the tensioner adjuster bolts 20-30 N.m, to be fine-tuned with reference to the corresponding Iveco model manual. Fit the 10PK drive belt over the alternator pulley, crankshaft pulley and any driven pulleys, and tension the belt to the manufacturer specification; a belt that is too loose will slip under load and a belt that is too tight will damage the alternator bearing.
Connect the wiring in the sequence of low-voltage first, high-voltage second: connect the small excitation/control terminal (marked L or D+) to the warning-lamp or regulator control wire; connect the battery positive output cable to the main B+ terminal and tighten the nut securely, ensuring the cable lug is closely attached with no gap. Ensure the alternator housing is grounded through the mounting bracket, free of rust and oil stains. Secure the wire harnesses to avoid contact with hot exhaust components and moving parts, reinstall the fan shroud and belt covers, reconnect the negative battery cable, and check that all connections are tight.
After installation, start the engine and check that the battery warning lamp goes out and that the charging voltage settles at approximately 27-29V at 1500 rpm and above. Verify that the belt does not squeal under load. If the charging voltage is out of range, check the belt tension, the wiring connections and the regulator before further testing. Never run the alternator with the battery disconnected, as this can damage the regulator.
