        Warranty Method: Return to Sparky Direct

        All Major Tech Meters sold through Sparky Direct are covered by the manufacturer’s warranty. If you believe your meter is faulty or defective, you may request an assessment under this warranty policy.

        How to Lodge a Warranty Claim

        To initiate a warranty claim:

        1. Return to Sparky Direct

        Assessment Process

        Major Tech’s service lab will assess the returned unit to determine:
