CHECKING THE CHARGING CIRCUIT

1 – Static control values (engine off) 450 SEF-R.

Battery voltage > 12.5V.

A – Stator windings resistance values :

Y1-Y2 Y2-Y3 Y1-Y3 0.44Ω±10%

B – Resistance of the engine speed sensor : 117Ω±10%

Check that there is no continuity between the windings and the mass of the motorbike.

2 – Dynamic control values :

Engine speed sensor :

1.7V MIN/300 RPM. 120V MAX/10000 RPM.

Tension regulator :

Alternative (AC 200V caliber). Idle : 22V ±2V. At 6000 RPM : 77V±3V.

Direct :

On regulator output (DC 20V caliber). At 4000 RPM : 14.6V + Red/White, - Green.

Alternator :

Tolerance values = -5% /+10%.
