Predator 670 Wiring Jun 2026

| Wire Color | Function | Termination Point | | :--- | :--- | :--- | | | Battery positive (12V constant) | Starter solenoid (large post) & key switch B terminal | | Black | Ground / Chassis negative | Engine block, battery negative terminal | | Yellow (2x) | AC output from charging coil (unrectified) | Voltage regulator input | | Red/White | DC output from regulator (charged battery voltage) | Key switch B terminal or battery + | | Green | Low oil sensor signal | Low oil switch (closed when low) | | Black/Yellow | Magneto kill wire (ground to stop) | Key switch M terminal & low oil sensor | | Blue | Starter solenoid trigger (12V from start key) | Solenoid small terminal (S) | | White/Green | Fuel solenoid positive (12V when key in On or Start) | Carburetor fuel solenoid |

The solenoid at the bottom of the carburetor prevents backfiring by cutting fuel when the engine is off. It requires 12V to stay open while running. If you are not using the factory key switch, you must wire this to a switched power source so it "opens" when the ignition is on. 4. Safety and Kill Switch

| Component | Function | Typical Location | | :--- | :--- | :--- | | | Generates high voltage for spark; shut off by grounding. | Under the blower housing, one per cylinder. | | Starter Motor | 12V DC motor; engages flywheel ring gear. | Mounted to the engine block, right side. | | Starter Solenoid | Heavy-duty relay to engage starter. | Often remote-mounted (frame/ battery box). | | Charging Coil (Alternator) | 3A or 18A AC output (under flywheel). | Under flywheel; wires exit near blower housing. | | Voltage Regulator/Rectifier | Converts AC to DC for battery charging. | Black module attached to blower housing (if equipped). | | Low Oil Sensor | Grounds magneto if oil level is low. | Inside crankcase; wire exits near base. | | Ignition Switch | Keyswitch with Off/Run/Start positions. | Remote panel. | | Fuel Solenoid (Anti-afterfire) | Shuts off fuel to carburetor bowl when key is Off. | Bottom of carburetor float bowl. | predator 670 wiring

The sun was brutal, a hammer pressed flat against the back of my neck. I wiped a grease-stained hand across my forehead, likely leaving a streak of black sludge, but I didn’t care. I was staring down the barrel of a Saturday afternoon well-spent, or a complete disaster. It all depended on the Predator 670.

This is the moment of truth for any engine wiring job. I let it warm up for thirty seconds, the throttle governor moving the linkage up and down. | Wire Color | Function | Termination Point

: For repowers (like John Deere or Bolens tractors), pre-made harnesses from specialty vendors such as Vegas Carts are frequently used to replace the often-fragile factory control box.

I used crimp connectors, squeezing them tight with my pliers until my knuckles turned white. I wrapped the connections in electrical tape, layering it thick to keep the moisture out. | | Starter Motor | 12V DC motor; engages flywheel ring gear

or external alternator kits from Performance 670 can provide up to 40–70 Amps of output. Troubleshooting Common Issues

I spent the next hour tidying up the loom, using zip ties to secure the wires away from the hot exhaust header and the moving governor arm. It wasn’t factory-pretty, but it was bomber-proof.

The stock charging system on a Predator 670 is relatively weak, typically producing only about . This is enough to keep a battery topped off during long runs with no accessories, but it won't support headlights, winches, or high-end stereos.

I stripped the plastic sheathing back near the engine’s shroud. The kill wire on the engine was a pale color, usually white or gray on these units. I traced it from the ignition coil to the terminal block.
