Repair Services
ATV Electrical Diagnosis Before Parts Replacement
A dead battery, no crank, no spark, blown fuse, no charge or intermittent shutoff can all have different causes. We follow the circuit and test instead of guessing.
Starter Circuit Checks
Starter, solenoid, relay, switch and safety circuit testing for no-crank complaints.
Charging System Testing
Stator, regulator/rectifier, battery voltage and charging output checks.
Fuse & Ground Diagnostics
Blown fuse, bad ground, corrosion, poor connection and wiring fault testing.
Ignition Electrical Testing
Spark-related electrical checks including coil, switch, wiring and related circuits.
Intermittent Fault Checks
Help narrowing down electrical issues that come and go or appear after vibration, heat or use.
