Introduction
In the world of heavy equipment and field operations, repairs often happen far from the comfort of a well-stocked shop. When time is short and parts are scarce, ingenuity becomes the most valuable tool. This article explores a real-world repair involving a floating pump, a chewed spark plug wire, and a clever workaround that saved time, fuel, and frustration. Along the way, we’ll unpack relevant terminology, share anecdotes, and reflect on the broader culture of improvisational mechanics.
The Problem: A Chewed Spark Plug Wire
While preparing for a water-pumping operation, the operator discovered that the spark plug wire on a Watermaster floating pump had been chewed through—likely by rodents. This type of damage is common in rural and outdoor equipment storage, where wiring insulation can attract pests.
The Solution: NGK Spark Plug Wire Splicer
Rather than replacing the entire coil assembly, the operator recalled that NGK, a well-known manufacturer of ignition components, produces a spark plug wire splicer—a small device that joins two sections of wire securely.
Why the Watermaster Pump Matters
The Watermaster floating pump is a high-capacity unit capable of moving 700 GPM (gallons per minute), or 840 US GPM, using a relatively small 6 HP engine. Compared to other available pumps—a 3" and two 2" units—the Watermaster offered:
Anecdotes from the Field
One mechanic recalled a similar situation where a generator failed to start during a wildfire response. The culprit? A chewed ignition wire. With no splicer available, they stripped the wire ends and twisted them together with electrical tape—just enough to power a water pump and protect a fire line.
Another technician shared a story of a snowmobile stranded in deep powder. A broken spark plug wire was repaired using a piece of fencing wire and a soda can tab as a makeshift terminal. It ran long enough to get back to base.
These stories highlight the culture of improvisation that defines field mechanics—where necessity breeds invention and resourcefulness is a badge of honor.
Terminology and Tips
For those new to ignition systems or field repairs, here are a few key terms and concepts:
The repair of the Watermaster pump is more than a technical fix—it’s a reflection of the mindset that defines heavy equipment operators and field technicians. It’s about knowing your tools, trusting your memory, and having the confidence to improvise when the manual doesn’t have the answer.
In a world increasingly reliant on diagnostics and digital systems, these analog skills remain vital. Whether it’s a spark plug wire or a hydraulic fitting, the ability to adapt and overcome is what keeps machines running and operations moving.
Conclusion
The odd repair of a floating pump with a chewed spark plug wire may seem minor, but it encapsulates the spirit of field mechanics—resourceful, resilient, and ready for anything. With a bit of memory, a dash of luck, and the right part from a motorcycle shop, a potentially costly delay was avoided. In the end, it’s not just about fixing machines—it’s about keeping promises, meeting deadlines, and making the most of what you’ve got.

While preparing for a water-pumping operation, the operator discovered that the spark plug wire on a Watermaster floating pump had been chewed through—likely by rodents. This type of damage is common in rural and outdoor equipment storage, where wiring insulation can attract pests.
- Spark Plug Wire: A high-voltage cable that delivers current from the ignition coil to the spark plug.
- Ignition Coil: Converts low-voltage battery power into the high-voltage pulse needed for spark ignition.
- Rodent Damage: Mice and squirrels often chew wires for nesting material or due to the soy-based insulation used in modern cables.
The Solution: NGK Spark Plug Wire Splicer
Rather than replacing the entire coil assembly, the operator recalled that NGK, a well-known manufacturer of ignition components, produces a spark plug wire splicer—a small device that joins two sections of wire securely.
- Wire Splicer: A mechanical connector that allows two wires to be joined without soldering.
- Spark Plug Cap: The terminal that connects the wire to the spark plug, often containing a resistor to suppress electrical noise.
- Field Repair Strategy: By sourcing a splicer, wire, and cap from a motorcycle repair shop, the operator avoided a full teardown and restored functionality quickly.

- Higher Flow Rate: About 150 GPM more than the combined output of the other pumps.
- Fuel Efficiency: Lower fuel consumption due to its optimized design.
- Lay-Flat Hose Compatibility: Uses 6" lay-flat hose, ideal for rapid deployment and minimal friction loss.

Terminology and Tips
For those new to ignition systems or field repairs, here are a few key terms and concepts:
- Dielectric Grease: Used to seal and protect electrical connections from moisture and corrosion.
- Continuity Test: A method using a multimeter to check if electricity can flow through a wire or circuit.
- Heat Shrink Tubing: A protective sleeve that contracts when heated, used to insulate spliced wires.
- Resistor Cap: A spark plug cap with built-in resistance to reduce radio frequency interference (RFI).
- Spare wire and connectors
- Electrical tape and zip ties
- A basic multimeter
- A small tube of dielectric grease
