Setup and Installation
The Auto Meter 6145 gauge is compatible with 12 and 16-volt electrical systems, making it suitable for a wide range of street and race vehicles. Proper installation is crucial for accurate readings and safe operation.
- Mounting the Gauge: Select a suitable location for the gauge within the vehicle's dashboard or a dedicated gauge pod. Use the provided mounting hardware to secure the gauge firmly. Ensure the location allows for clear visibility and does not obstruct vehicle controls.
- Wiring Connections: Utilize the included wiring harness to connect the gauge to the vehicle's electrical system. Follow the detailed wiring diagram provided in the separate installation sheet for correct power, ground, and illumination connections. Incorrect wiring can damage the gauge or vehicle electronics.
- Thermocouple Installation: Install the Type-K Thermocouple into the exhaust system using the thermocouple mounting kit. The thermocouple should be positioned to accurately measure exhaust gas temperature. Ensure a secure, leak-free installation. The Type K thermocouple is essential for maximum accuracy and minimum response time.
- Final Checks: After all connections are made, double-check all wiring for proper routing, secure connections, and insulation. Ensure no wires are pinched or exposed to excessive heat.
Operating Instructions
Once installed, the Auto Meter 6145 Pyrometer Gauge operates automatically when the vehicle's ignition is turned on.
- Power-Up Sequence: Upon initial power-up, the gauge will perform a self-calibration sequence. This process ensures the digital stepper motor instruments provide unmatched accuracy. Allow the gauge to complete this sequence before relying on readings.
- Reading the Gauge: The full sweep electric movement provides precise and easy-to-read exhaust gas temperature indications.
- Nighttime Visibility: The modern blue LED through-the-dial lighting ensures clear visibility of the gauge readings during nighttime operation.
Maintenance
The Auto Meter 6145 Pyrometer Gauge requires minimal maintenance to ensure long-term performance.
- Cleaning: Clean the gauge face and bezel with a soft, damp cloth. Avoid using abrasive cleaners or solvents, which can damage the finish.
- Connection Checks: Periodically inspect all electrical connections and the thermocouple installation for tightness and integrity. Ensure no wires are frayed or corroded.
- Thermocouple Inspection: Check the thermocouple for any signs of damage or wear, especially if exposed to extreme conditions. Replace if necessary to maintain accuracy.
Troubleshooting
If you experience issues with your Auto Meter 6145 Pyrometer Gauge, consider the following troubleshooting steps:
- Gauge Not Powering On: Check the power and ground connections at the gauge and at the vehicle's electrical system. Ensure the fuse in the power circuit is intact.
- Inaccurate Readings: Verify the Type-K Thermocouple is correctly installed and securely connected to the gauge. Inspect the thermocouple for damage. Ensure the gauge has completed its self-calibration sequence.
- No Backlighting: Check the illumination wire connection and ensure the vehicle's lighting system is active.
- Erratic Readings: Inspect all wiring for loose connections, shorts, or interference from other electrical components.
If problems persist after performing these checks, contact Auto Meter customer support for further assistance.
