How do you install a Tach Adapter?
Position the Tach Adapter away from excessive heat sources and mark the locations of the three mounting holes. Use a 5⁄32” bit to drill holes and secure the unit with the supplied screws. Route the wires away from direct heat sources, moving components, and sharp edges.
Do I need a Tach Adapter?
If, after installing an MSD Ignition Control, your tachometer, fuel pump relay or electronic fuel injection (in foreign vehicles) doesnt operate correctly, your application may require a Tach Adapter. This is due to the trigger signal not being strong enough to trigger both the MSD and the factorys components.
How does a Tach Adapter work?
The Auto Meter Tach Adapter wires in line on the positive 12 volt supply wire. It senses current on the coil positive wire and converts it to a 12 volt signal output. The Tach Adapter is designed to be mounted under the hood. The circuits are potted in polyurethane for water resistance and vibration protection.
What does an MSD tach adapter do?
MSD magnetic pickup tach adapters maintain accurate tachometer readings. If you are using the magnetic pickup input (green and violet wires) to trigger your MSD Ignition, you will need one of these tach adapters.
How does a MSD tach adapter work?
Each adapter is simple to wire in and will have your MSD and vehicle firing away in no time. The PN 8920 will correct the operation of most voltage-triggered tachometers that do not work directly off the tach output terminal of the MSD control.
How do you test an MSD tach adapter?
Set a volt meter to 10 volt DC. Start the car, one meter lead on the tach output with the other to ground. The volt meter shouild read anywhere between 1-5 volts if the tach output is operating properly. Output direst from MSD 6 box at 600 rpm reads 2.34 vdc.
When would you use a tachometer?
A tachometer is an instrument which measures the rotation speed of a shaft or disk. It is designed to measure the revolutions per minute (RPM) of a moving object. Tachometers are typically used in motors and other machines and are widely found in the automotive and aviation industries.
How do you install a tach adapter on a car?
To install the Tach Adapter, the coil positive wire must be identified for your application. Once the wire has been located it is recommended to check for 12 volts using a volt meter. Connect the meter and turn the ignition On. In some cases, the engine must be cranked over in order to see 12 volts.
