C. Voltage Regulator (XS750-2D Only)
The regulator has been changed from a
mechanical-point type t o an IC(Integrated
Circuit) type. The IC Voltage Regulator
is
a
small and normally very reliable component.
Due to i t s construction, it is lightweight and
free from the wear and misadjustment
asso-
ciated wi th mechanical voltage regulators.
I f the following inspection reveals that the
regulator is faulty, it cannot be adjusted and
must be replaced.
Checking IC Voltage Regulator
1.
Measure the specific gravity o f the bat-
tery fluid. I f it
is
less
than 1.26, remove
the battery and recharge until it is more
than 1.26.
2. Remove the left
hand
side cover.
3. Check the battery terminals and couplers
for looseness.
4. Connect two Yamaha pocket testers to
the regulator coupler as illustrated.
CAUTION:
Beware of short-circuiting when con-
necting tester lead wires to the coupler.
