Frequently Asked Questions
Will this alternator fit without modification?
Yes. This is a direct OEM-fit replacement for the listed Ford, New Holland and International applications, using the same mounting and pulley configuration as the original.
What's included?
The alternator unit, ready to bolt straight into place of the original. Various 15mm ID pulleys can be fitted to the V1-class pulley boss.
How can I tell my original alternator has failed?
Common signs include a dead or slowly-draining battery, dimming or flickering lights, an illuminated charge warning light, or a whining/growling noise from the unit.
Why is the regulator described as thermistor-sensing?
This unit uses a thermistor-sensing internal regulator, which adjusts charging voltage in response to temperature for more consistent battery charging across a wide operating range.
