Checking The Charging Circuit - SHERCO 2015 450 SEF-R Workshop Manual

Checking the charging circuit

1 - Static control values (engine off) 450 SEF-R.
Battery voltage > 12.5V.
A - Stator windings resistance values.
B - Resistance of the engine speed sensor: 117 Ω ± 10%
Check that there is no continuity between the windings and the mass of the motorbike.
2 - Dynamic control values:
Engine speed sensor
1.7 V MIN/300 RPM
120 V MAX/10000 RPM
Tension regulator:
Alternative (AC 200 V caliber).
Idle: 22 V ± 2 V
At 6000 RPM 77 V ± 3 V.
Direct :
On regulator output (DC 20 V caliber).
At 4000 RPM 14.6 V + Red/White, - Green.
