4. Loosen the generator 4 mm hex key mounting bolt enough so that the generator can
be moved forward. Move the generator forward to loosen tension and remove the belt
off the generator pulley.
5. Remove the 4 mm hex key bolt and washer mounting fasteners and remove the gen-
erator.
Installation procedure
1. Install the generator onto the cross member and secure using the 4 mm hex key bolt
and washer fasteners. Loosely tighten the fasteners allowing forward and rearward
movement.
2. Install the generator belt onto the generator and flywheel generator pulleys.
3. Route the generator interface cable across the cross member and connect to the
LPCA - J5 connector. Reinstall the previously removed two cable ties that hold the
generator and other electrical component interface cables to the cross member.
4. Adjust the generator belt tension see
"Generator Belt Tension Adjustment" on
CAUTION
: Do not over tension the belt which will lead to premature belt wear and
possible damage to the generator pulley.
5. Access the console service test menu and select
RPM
. Pedal the bike and verify that
the RPMs value is showing and varies with pedal speed.
Note
: RPM is computed from pin 3 of the generator cable connector. If this gen-
erator output phase has quite working, the console may not operate and will not dis-
play
RPM
.
6. Ride and pedal the bike at 60 rpms and verify that the generator is providing the spe-
cified charging voltage and current. Access the console service test menu and verify
the generator voltage and current outputs:
l
GEN VOLT
: approx. 9 Vac @ 60 rpm (voltage will increase as rpms increase)
l
GEN AMP
: approx. 0.4 amps @ 60 rpm (current will increase as rpms
increase)
7. Reinstall the front and rear drive belt covers, see
"Belt Guard Cover Replacement" on
8. Verify the bike operation per
"Operation Verification Checklist" on page 14
and return
to service.
