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
small and normally very reliable component.
Due to i t s construction, it is lightweight and
free from the wear and misadjustment asso-
ciated w i t h 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
3. Check the battery terminals and couplers
for looseness.
4. Connect t w o Yamaha pocket testers to
the regulator coupler as illustrated.
CAUTION:
Beware of short-circuiting when con-
necting tester lead wires to the coupler.
