| Yellow | Ignition switch connection |
| Red | Battery connection |
If the ignition coil is faulty, you may experience issues with starting the engine or a weak spark output. In such cases, you may need to replace the ignition coil.
The Starter Solenoid
The starter solenoid is responsible for engaging the starter motor when you turn the key in the ignition switch. The wiring connections for the starter solenoid are as follows:
| Wire Color | Connection |
|---|---|
| Black | Ground connection |
| Red | Ignition switch connection |
| Yellow | Starter motor connection |
| Blue | Battery connection |
If the starter solenoid is faulty, you may experience difficulties in starting the engine, and the starter motor may fail to engage. In such cases, you may need to replace the starter solenoid.
The Voltage Regulator
The voltage regulator is responsible for regulating the voltage output of the engine’s charging system. It is connected to the alternator and battery to ensure that the battery is charged efficiently. The wiring connections for the voltage regulator are as follows:
| Wire Color | Connection |
|---|---|
| Green | Alternator connection |
| Red | Battery connection |
If the voltage regulator is faulty, you may experience issues with the charging system, and your battery may not be charged efficiently. In such cases, you may need to replace the voltage regulator.
The Battery
The battery is responsible for providing power to the engine’s electrical components, including the starter motor and ignition system. It is connected to the starter solenoid, voltage regulator, and ignition coil. If the battery is faulty or weak, you may experience issues with starting the engine or a weak spark output.
