Frequently Asked Questions
How do I check this alternator fits?
Compare the part number on your existing unit against the cross-reference table above, and check the output rating and pulley type. Send us your vehicle or engine details if you are unsure.
Is this new or remanufactured?
It is 100% new, not a rebuilt core - no core charge and no worn slip rings or bearings.
Is the pulley included?
Unless stated otherwise the unit is supplied without a pulley - transfer the one from your original alternator.
My battery keeps going flat - is the alternator to blame?
Measure voltage at the battery with the engine running: roughly 13.8-14.4V means it is charging. Below that, with a good belt and clean connections, the alternator or its regulator is the likely cause.
