Questions & Answers
Is this a genuine original part?
This is a premium quality 4Drive aftermarket replacement part, manufactured to meet or exceed original Delco Remy standards for performance and fitment.
What does "12:00 Clocking" mean?
Clocking refers to the position of the wiring harness plug relative to the main mounting bolt when looking at the back of the alternator. 12:00 means the plug is directly opposite the bottom mounting foot.
Can this be used for 1-wire systems?
This specific unit is configured as a standard 3-wire 10SI. While it can be converted with a self-exciting regulator, we recommend checking your specific wiring requirements before installation.
Note: Please verify your original part number and clocking position against the references above before purchasing. For expert support, contact 4Drive.
