3.3 Installing the chain counter
The chain counter must be positioned so that the display will be easy to read. It should not be exposed to direct sunlight. For mounting
the female connector, drill on the dashboard one hole of 20 mm (~13/16") and secure the female plug with the back locking nut (Fig. A)
to dashboard with a thickness not exceeding 10mm.
Put the gasket between the rear part of the plug and the dashboard.
For instructions on making electrical connections, see the wiring diagram with the table below (Fig.B).
20mm
If possible mount the connector in a dry place so the rear part of the plug must be protected from contact with water or moisture.
The wires must have a minimum cross section size of 1.5 mm². Install a 5 A (ampere) fast safety fuse on the positive(+) wire of the battery.
Do not use the voltage generated by the engine battery set to provide power.
Series resistor recommended for >5m sensor cable length
The instrument complies with EMC standards and must be positioned at a distance of:
