Introduction
The EMS-3 is a multifunction engine information display and early warning engine monitoring system. It has been
specifically designed to monitor crucial vehicle information, and in the event of any engine irregularities, it will alert the
driver by means of a visual and audible alarm.
With its array of advanced features, the EMS-3 is an indispensable unit for the discerning vehicle owner. Costly
maintenance bills can easily be avoided by the prevention of major engine problems before they occur.

  • Page 28: Installation

    10.1 Connection Diagram The use of an external 1A fuse is recommended. Connect the supply terminals to your vehicles power supply. The EMS-3 can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop below 8V during operation as this may result in incorrect readings.

  • Page 30 – if this is the case then the plates can be removed and tapped to accommodate the EGT probe. Your Madman supplier should then also have this plate in stock as a listed adapter for that engine. If you have an EGR valve fitted, remove it entirely and disable the diaphragm by removing the wiring loom or vacuum pipe.
