Unfortunately, Delta-Q does not offer repair or replacement services.
Contact the OEM of your vehicle or machine or the distributor you purchased the charger from for any service requests.
Delta-Q does recognize that you may value repair and re-use of your existing charger rather than having to scrap it. Though Delta-Q does NOT have any "authorized" repair centers, if you do wish to explore repairs we suggest you contact Flight Systems Industrial Products, who specialize in repair and remanufacture of industrial electronics. They will also be able to offer you a new Delta-Q charger if repair is not feasible.
