Imagine the wiring as three distinct loops:
If engine starts then dies after 2 seconds, check 12V on orange wire. Predator 670 Wiring Diagram
The signal wire for the starter solenoid. Applying 12V power to this wire tells the starter to spin. Yellow (Fuel/Accessories): Controls the carburetor solenoid Imagine the wiring as three distinct loops: If
| Function | Wire Color (Stock) | Voltage State (Key ON) | Voltage State (Start) | Resistance to Ground | | :--- | :--- | :--- | :--- | :--- | | Battery Power | Red (Heavy) | +12V | +12V | Infinite | | Chassis Ground | Black | 0V | 0V | 0 Ohms | | Solenoid Trigger | Brown | 0V | +12V | Infinite | | Magneto Kill | Black/White | 0V (Grounded) | 0V | 0 Ohms (when key OFF) | | Fuel Solenoid | Blue | +12V | +12V | 20-50 Ohms | | Stator AC | Yellow (x2) | N/A (Engine running) | 28V AC | Low (0.5 Ohms between yellows) | Predator 670 Wiring Diagram
The Predator 670 electrical system relies on a few critical connections to ensure reliable starting and operation:
| Switch Terminal | Wire | Function | |----------------|------|-----------| | (Battery) | Red (from battery or solenoid) | Constant 12V | | S (Start) | Blue | To starter solenoid trigger | | I (Ignition) | Orange | To fuel solenoid, sometimes regulator sense | | M (Magneto kill) | White/Red | To magnetos & oil pressure switch | | G (Ground) | Black | Sometimes not used (grounds internally) |
