Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your Faria 33750 Chesapeake Tachometer. This 7000 RPM gauge is designed to accurately measure engine revolutions per minute (RPM) by interpreting electrical pulses from your engine's ignition system, alternator, or dedicated signal generator. It features a built-in warning light system to indicate engine faults.
Package Contents
- Faria 33750 Chesapeake Tachometer 7000 RPM Gauge - Black SS, 4"
- Mounting hardware (screws, nuts, washers)
- Wiring harness (if applicable, typically included for basic connection)
- Instruction sheet (this manual)
Setup & Installation
The Faria 33750 Tachometer is designed for straightforward installation. Proper wiring and configuration are crucial for accurate readings.
- Mounting: Select a suitable location on your dashboard or panel. The gauge has a 4-inch diameter. Ensure sufficient clearance behind the panel for wiring and the gauge body. Secure the gauge using the provided mounting hardware.
- Power Connection: Connect the tachometer to a +12V DC power source. This connection typically goes to a switched ignition circuit to ensure the gauge powers on and off with the engine.
- Ground Connection: Connect the tachometer to a reliable ground point on your vessel's electrical system. A solid ground connection is essential for stable operation.
- Signal Input: The tachometer receives RPM signals from various sources. Connect the signal wire to one of the following:
- Ignition system (e.g., coil negative terminal)
- Alternator (specific tach output terminal)
- Dedicated tach signal generator
- Magnetic pickup sender
- Pulse Setting: On the back of the tachometer, there is a switch or set of switches to configure the number of pulses per engine revolution. Refer to your engine's specifications or the detailed wiring diagram provided with the gauge to set this correctly. Incorrect settings will result in inaccurate RPM readings.
- Warning System Connection (if applicable): If your model includes System Check, Suzuki Monitor, or OBD warning systems, connect the relevant wires according to the specific wiring diagram for your engine and system.
Operating Instructions
Once properly installed and configured, the Faria 33750 Tachometer operates automatically when the engine is running.
- RPM Display: The needle on the gauge will indicate the engine's current RPM. The scale ranges up to 7000 RPM.
- Warning Light System: This tachometer incorporates a warning light system directly into the dial. These indicators illuminate when a fault is detected from the engine's monitoring system (e.g., low oil pressure, high temperature, check engine). Consult your engine's manual for specific fault codes or warning light interpretations.
Maintenance
The Faria 33750 Tachometer requires minimal maintenance to ensure long-term performance.
- Cleaning: Clean the gauge face and bezel periodically with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or lens.
- Connections: Periodically inspect all electrical connections for corrosion or looseness. Ensure all wiring is secure and free from damage.
- Environmental Protection: While designed for marine environments, protecting the gauge from extreme weather conditions when not in use (e.g., with a boat cover) can extend its lifespan.
Troubleshooting
If your tachometer is not functioning correctly, consider the following common issues:
- No Reading or Incorrect Reading:
- Check all power (+12V DC) and ground connections for proper contact and voltage.
- Verify the signal wire connection to the engine's RPM source.
- Ensure the pulse setting switch on the back of the gauge is correctly configured for your engine.
- Inspect wiring for any cuts, pinches, or corrosion.
- Warning Lights Illuminated:
- If a warning light illuminates, it indicates a detected fault from your engine's monitoring system. Consult your engine's owner's manual for specific diagnostic procedures related to the illuminated indicator.
- Do not ignore warning lights; address the underlying engine issue promptly.
- Gauge Not Powering On:
- Check the +12V DC power supply and ensure the circuit is active.
- Verify the ground connection.
- Check for any blown fuses in the power circuit.
