  • Most of the Delco regulators we used to service are around 30 years old and have several obsolete components. As a result, hardly any can be rebuilt and the older Delco units were eliminated from our program.
  • TEST ONLY - There is a test fee of $35(slightly higher for complex ATS controls). Boards received that test as "NTF" (No Trouble Found) are charged this fee.
  • Factory Direct Prices Shown - RE-SELLERS (Gen Set, Marine & RV Dealers/Distributors/Repair Shops) call for your Discounted Pricing!
  • "P" = PLUS PARTS. Required components totaling over $5 are an extra charge and will be itemized on the invoice. Other required components and material are included in the rebuild price at no extra charge.
