Auto Meter 2-1-16 Inch Pyrometers
Important
Pyrometers are sensitive, high-accuracy instruments. They must be handled and
installed with care to ensure proper performance. Carefully read and follow
these instructions, and your pyrometer will provide you with a long and
accurate life.
Caution
Wear safety glasses and disconnect the battery before making any electrical
connections.
Installation
Lighting
- The 2 5⁄8″ gauges may be mounted in a 25⁄8″ diameter hole. The 2 1⁄1 6″ gauges may be mounted in a 2 1⁄1 6″ diameter hole. The hole may be either a hole in the dash, a gauge panel, or an Auto Meter Gauge Pod. (It is best to connect all wiring to the gauge before mounting it into the gauge hole.)
- Follow the GENERAL WIRING diagram to connect 12-volt lighting. See PROBE INSTALLATION below to install the probe.
Probe Installation
Begin by installing the Thermocouple in the exhaust, then work back to the gauge. For turbo engines, install the probe 1-2 inches from the turbo exhaust outlet. For non-turbo engines, install the probe 1-2 inches from the cylinder head. Installing the probe in the proper location will ensure optimal temperature readings. The probe can be mounted in three different ways, so please use the method best suited to your needs.
- Pre-existing 1⁄8″ NPT Threaded Hole: Simply screw the threaded fitting into the hole, insert the probe, and tighten the nut already on the probe from the factory. Make sure the probe is oriented so the wires do not come in contact with, or become too close to, the manifold or other hot engine parts.
- Weld Fitting: Drill a 9 ⁄16″ hole and weld in the supplied bushing being careful not to distort the bushing. The bushing must be welded and not braised into the manifold or exhaust header. Screw the threaded fitting into the hole, insert the probe, and tighten the nut already on the probe. Make sure the probe is oriented so the wires do not come into contact with, or become too close to, the manifold or other hot engine parts.
- Stainless Clamp Method: This method is for applications that require frequent removal of the manifold or the header for service, or just faster and easier installation. Drill a 1⁄4” diameter hole about 6” down from the junction of the exhaust pipe to the manifold junction.
- Remove the 1⁄8” NPT bushing from the probe and replace it with the stainless clamp and set the screw collar provided. Undo the clamp and slide the probe into the 1⁄4” hole in the clamp. Slide the set screw collar onto the probe. Before tightening the collar in position make sure that when inserted, the probe will have its tip in the middle two-thirds of the exhaust stream. (It is not necessary to go beyond the halfway point.) Hold the clamp open when inserting the probe into the 1⁄4” hole. Re-join the clamp ends and tighten in position so the wires will not get close to the hot manifold/exhaust pipe. See the Illustration below for details.
- With your probe installed, the extension wire can now be connected to the probe and routed to the gauge. Pull the large shrink tube back from the screw connections on the probe. Attach the staggered end of the extension wire with the small (No. 6) ring terminals to the probe using the #6 screw and self-locking nuts. Attach them Red to Red and Yellow to yellow. Slide the shrink tube over the staggered connections to protect them. Do not shrink this tube until after the installation is complete, and the correct operation is verified. If a heat source is not available the open ends may be closed with tie wires.
- The extension wire is an integral part of the pyrometer calibration. It may not be shortened or lengthened without affecting the gauge calibration. You’ll need to determine a suitable location to coil the excess and tie it loosely with a wire tie. (Loosely tying the excess coil prevents embrittlement caused by vibration.) Pass the extension wire through the firewall using an existing hole or drill an 11⁄3 2” (.343”) diameter hole and use the rubber grommet provided to protect the wire from damage. Route the wire to the gauge and connect the No. 8 terminals to the studs on the back marked Yellow+ and Red-. Fasten using the split lock washer and brass nuts provided.
