What's wrong?
The V-MUX 8 x 16 Input / Output Node on the 2020 Spencer Pumper is an electrical control module. It receives switch or system inputs and turns outputs on and off, which lets truck equipment and body wiring operate through controlled circuits instead of direct manual wiring.
The defect is in the node firmware, which is the software inside the module. In a short circuit or wiring failure, that firmware fails to shut off the output pin. Once the output pin stays on, the affected circuit stays energized and the electrical circuit can overload.
There is no warning sign before failure. The recall filing says Spencer had no complaints or warranty claims from customers, so owners should not rely on a symptom or prior service history to identify the problem.

What's the safety risk?
Overloaded electrical circuits can overheat and increase the risk of fire. Treat electrical burning smells, smoke, or unusual heat as a reason to stop using the affected equipment and call the dealer, but do not wait for a warning sign before scheduling service. Repair is free at any franchised Spencer dealer.
What should I do?
- Check your VIN to confirm your 2020 Spencer Pumper is included in this recall.
- Contact a franchised Spencer dealer to schedule the free Weldon 8X16 firmware update that helps the node shut off output pins after a short circuit or wiring failure.
- Bring the recall notice if Spencer has mailed one. If not, reference recall number 24V126 when you call.
- Keep the truck scheduled for repair before extended service use, because overloaded electrical circuits can overheat and raise the risk of fire.
What happens at the repair
At the dealer or service location, a Spencer technician updates the firmware for the Weldon input output node. The update is intended to let the node shut off the output pin during a short circuit or wiring failure, which helps prevent overloaded electrical circuits. The recall repair is free, with parts and labor covered. Spencer lists a general reimbursement plan for owners who already paid for a related firmware repair. Keep your repair paperwork and contact Spencer customer service about submitting a claim.
