What's wrong?
The Hercules HC 1.7 Node on the 2024 Spencer Pumper is an electrical control module. It receives commands and sends power out through output pins to run vehicle circuits. Its firmware, the software inside the module, is supposed to shut an output off when the circuit is overloaded.
On affected Pumpers, the electrical current sensing calibration in the node firmware does not respond correctly during a short circuit or wiring failure. Instead of shutting off the output pin, the node can keep feeding the circuit. That overloads the electrical circuit and can overheat the node.
The recalled nodes are identified by firmware version, with version 1.00 included in the recall range. There is no warning sign before failure, so an owner or fleet technician should not rely on a dashboard light, noise, or drivability change to spot the problem.

What's the safety risk?
An overloaded electrical circuit can overheat and increase the risk of fire. Until the firmware update is completed, schedule service promptly and take any sign of overheating, smoke, or burning odor seriously by shutting the vehicle down and calling Spencer service. Repair is free at any franchised Spencer dealer.
