NOTE:
A volt/amp tester equipped with both a battery load control (carbon pile) and an inductive-type pick-up clamp is required to perform following test.
- Ensure battery is in good condition and is fully charged. Clean battery terminals (if necessary). Connect volt/amp tester leads to battery. Ensure carbon pile is in OFF position before connecting leads. Connect inductive pick-up clamp.
- Connect tachometer to engine. Start engine and raise engine speed to 2500 RPM. Slowly adjust rheostat control (load) on volt/amp tester until highest amperage reading is obtained. DO NOT allow voltage to drop less than 12 volts.
- Note reading on ammeter. Generator amperage reading should be greater than minimum amperage rating specification. See GENERATOR APPLICATIONS table under DESCRIPTION. If amperage is not within minimum specification, go to next step.
- Rotate load control knob to OFF position. Continue to hold engine speed at 2500 RPM. Output amperage should change to less than 20 amps, indicating EVR circuity is okay and charging system is functioning properly. It may take several minutes for amperage to change. If amperage does not significantly decrease, check battery. Using scan tool, check for any possible DTCs. See SELF-DIAGNOSTIC SYSTEM .
NOTE:
Depending on volt/amp tester manufacturer, load may be applied automatically. Refer to volt/amp tester manufacturer's instructions.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
