Once the engine is started, the pushbutton can be released. (It is possible to calibrate the tachometer without engine running) The pushbutton must be pressed until the engine is started (if not a few seconds after). When this happens, power is cycled and the speedometer is no longer in calibration mode. If you are having troubles calibrating, make sure to press the pushbutton extra hard to insure it is making contact.Ī common mistake is a customer will enter calibration mode to set the speedometer and then start the engine.

The pushbutton does not move very much when pressed making it hard to tell if you are actually getting the pushbutton to work. Check for continuity through pushbutton (should have continuity only when button is being pressed) Sometimes the pushbutton is not connected to a ground.

Is the speedometer pointer at 30mph or 45mph when doing a marked mile calibration?.

Are you pressing the pushbutton until the engine is started? Necessary when calibrating speedometer.

Is the pushbutton connected properly? One wire to ground and one to brown harness wire.

Speedometer Calibration – Ultimate Technology If you don’t have a meter, disconnect the power wire from speedometer or positive wire from the battery to make absolutely sure the power is off. Check the voltage to the speedometer with a meter. If no change is seen after you have made dip switch changes, verify that power was off when the changes were made. Make sure they are all “clicked” in the correct position by toggling every switch once and then setting the default again. Sometimes a dip switch will look like it is pressed in the correct position but it hasn’t “clicked” and is not making contact in the correct direction. Make sure the dip switches on the speedometer are not set backwards. If you have an ECM signal, set the SN74 switches to 1,2 ON with the speedometer dip switches set to 5 6 7 8 OPEN. If you have a VSS signal from a transmission or any 2-wire sender (i.e SN96, SN95), make sure you are using the SN74 with switches 1-4 OFF (2 may be ON if you are experiencing interference) and have the speedometer dip switches set to 5 6 7 8 OPEN. If you are using a SN74 along with the SN16, make sure the dip switches are also set at the default (5 6 7 8 OPEN).

If using SN16, make sure you are using the 16000ppm calibration chart and dip switches 5,6,7,8 are OPEN. Are you sure power is off to the speedometer when you make a change to the dip switches?.In what position are the speedometer’s dip switches set?.Where are you getting signal?
