High Output Alternator for Mercury Tracer (1998-1999) 2.0L

High-Amp 250A Charging Alternator for 1998-1999 Mercury Tracer (CT120)

What it Does: The 250-Amp High Output Alternator replaces the low-output factory charging unit on the 1998-1999 Mercury Tracer to eliminate voltage sag and supply stable current under heavy auxiliary electrical loads.

The Stock Mercury Tracer Alternator Limitation

Factory charging systems on the CT120 chassis Mercury Tracer were engineered with modest 75-to-90 amp outputs intended purely for basic baseline accessories. When paired with high-draw equipment—such as aftermarket audio amplification, auxiliary lighting, or performance electric cooling fans—the OEM stator windings saturate and overheat. This results in severe voltage drops below 12.6V at idle, premature diode rectifier failure from excessive heat soak, and constant battery drain on the SPI 2000 2.0L powertrain.

The Engineering Solution

Manufactured in the USA, this high-output 250-amp alternator features precision-wound, heavy-gauge copper stators and high-efficiency avalanche diode rectifiers designed to maximize electrical throughput while minimizing thermal resistance. Encased in a rugged aluminum housing for superior passive heat dissipation, it produces massive output gains over stock across the entire RPM band. The rotor assembly is dynamically balanced to maintain reliability at high engine revs, directly interchanging with OEM reference F07F-10300-AA and 7750.

Frequently Asked Questions & Fitment Warnings

Does this fit the CT120 Tracer?

Yes, this is a direct bolt-in fit for the 1998-1999 Mercury Tracer equipped with the SPI 2000 2.0L SOHC engine.

Do I need upgraded wiring to install this 250A alternator?

Yes, completing a 1/0 or 4-gauge "Big 3" battery ground, chassis ground, and charging lead upgrade is required to safely support the 250-amp flow without overloading the stock harness.
