ground. If the EIS show a high temperature, the connection to the instrument is
good. If it does not change, check the wire between the instrument, and the oil
or coolant temperature sensor, especially the crimp on the quick-disconnect
that plugs onto the coolant temperature sensor.
Tach Reading is zero when one
mag is turned off. This is normal, as the tach signal is generated by one of the mags.
Tach is erratic. Tachometer resistor is not installed, or its value is too low. See wiring
diagram for tachometer connection.
Tach reading is steady, but too
low or too high. TachP/R is incorrectly set. See "Configuration Set Pages" section.
Voltmeter reads to high. All
else OK. An "update" version of software has been installed, and the setting on the
Units page (the H/N setting) is incorrect.
Voltmeter reads above 20 V
and other readings incorrect. More than 5 volts is being applied to an auxiliary input. This can be caused by
an incorrectly calibrated capacitance fuel fuel probe, a open ground wire to the
manifold pressure sensor, or similar. Check the aux inputs be see if any are
above 5 volts using a voltmeter.
