7.3 Electrical System
1. Battery
Trouble and possible cause Possible remedy
A. Frequently insufficient electric power
(1) Low electrolyte level
(2) Short circuit plates
(3) Plates sulphurized
(4) Defective generator or regulator
(5) Defective wire contraction
B. Battery overheated
(1) Short circuit of plates
(2) High changing electric current
C. Charge capacity of battery distinctively reduces
(1) Plates sulphurized
(2) Sulphuric acid not pure
(3) Plate curved, active material peeled off and spacer
damaged to cause short circuit
(1) Add to specified level
(2) Clean deposit, change electrolyte and
replace spacers or plates
(3) Charge repeatedly to remove sulphur
(4) Repair generator or regulator
(5) Check wire contraction to remove trouble
(1) Clean deposit, change electrolyte and
replace spacers or plates
(2) Adjust regulator
(1) Change repeatedly to remove sulphur
(2) Use proper electrolyte
(3) Replace plate
Trouble and possible cause Possible remedy
A. Generator will not work
(1) Rectifying unit damaged
(2) Block brush gripped and no contraction with
collector ring
(3) Stator winding or rotator winding broken circuit,
short circuit or negative pole and terminals
defective insulation.
B. Lack of generator power
(1) Loose generator belt
(2) Some rectifying unit damaged
(3) Defective block brushes and collector ring
stained with oil.
(4) Part of rotator winding or stator winding short
circuit.
(1) Adjust belt tension or replace belt
(2) Repair or replace rotator winding or stator
winding.
(3) Repair or replace block blush spring
