TOP 600 XTPRO: Service & Maintenance Manual - rev. 2.0
3.1.6. ALTERNATOR
Is put into rotation by the user, and generates a resistance to the movement proportional to the
excitation voltage received from the alternator interface board. It also generates the RPM signal (6
impulses per revolution) necessary for counting the number of revolutions and hence measuring the
speed. Its rotation produces energy which is dissipated by the power resistor.
There is a thermal cutout connected in series with the excitation circuit, which is normally closed
and opens when the temperature exceeds an established threshold.
3.1.7. POWER RESISTOR
Has the function of dissipating the energy produced by the alternator.
