What's wrong?
The Weldon 8 X 16 input-output node in these 2020-2023 Hi-Tech E.V.S. Spartan Gladiator and Spartan Metrostar fire trucks is an electronic control module. It receives commands and switches output pins on or off so electrical equipment gets power only when the truck calls for it.
On affected trucks, the current-sensing calibration in the node was outside specification. During an external short circuit or wiring failure, the firmware does not shut off the output pin as designed. That leaves the circuit energized, which can overload wiring and electrical circuits instead of stopping the fault.
There is no warning sign before failure. A crew or service shop should treat melted wiring, a burned electrical smell, or repeated circuit trouble as a reason to stop using the affected function and have the truck inspected.
Who's affected?
Covers both Spartan Gladiator and Spartan Metrostar vehicles across the 2020-2023 model years, all tied to the same input-output node wiring.

What happens at the repair
At the dealer, a Hi-Tech E.V.S. technician updates the firmware in the Weldon 8X16 Input-Output node so the system can shut off the output pin during a short circuit or wiring failure. Parts and labor are covered under the recall. If you already paid for a related firmware or electrical node repair before the owner notice, contact Hi-Tech E.V.S. customer service or Akron Brass customer service and ask how to submit documentation. Weldon says reimbursement is evaluated and provided on an individual basis.
