TESTING STARTING CIRCUIT
To prevent the possibility of injury resulting
from vehicle inadvertently starting, disconnect
battery for steps 1 through 8 (see Section “B”).

DVOM ......................................................................... 1
If the engine will
not
turn over, proceed as following
(Ref. Fig. 1):
1. Check the battery for a voltage reading which should
be between 12.2 and 12.5 volts. Inspect for loose or
dirty battery post connections.
2. Check for a blown in line fuse and replace if neces-
sary with a 7 amp fuse.
3. Check for loose wires at all terminal connections.
4. Check the complete electrical system for correct cir-
cuitry.
5. Inspect for worn insulation or bare wires touching the
frame. Bare wires will cause a short circuit.
6. Check for continuity through the key switch. Set the
DVOM to the ohms (
Ω)
scale. Detach wires. Place
positive (+) probe on one terminal and negative (-)
probe on the other terminal. The reading on the meter
should be “0”
Ω
with the switch key in the
‘
ON
’
posi-
tion and a visual signal (
∞
) with the switch
in the
‘
OFF
’
position. If the meter does not register, replace the
switch. Reconnect the wires.
7. Turn the key switch to
‘
OFF
’.
(a) Place one probe of the DVOM (set to ohms scale)
on the red wire at the solenoid. Place the other
probe on the key switch terminal with the blue wire.
(b) Press the accelerator and observe the DVOM. A
reading of less than 2
Ω
indicates a good limit
switch. A reading of greater than 2
Ω
indicates that
the switch terminals should be checked. A reading
of infinity a visual signal (•) indicates that the switch
must be replaced. Connect the battery.
8. Check the starting solenoid operation. Turn the key
switch to the
‘
ON
’
position.
(a) Place the DVOM (set to the appropriate DC volts
scale) negative (-) probe on terminal “A” of the
solenoid. Place the positive (+) probe on terminal
“B”. The DVOM should indicate approximately 12
V.
(b) Press the accelerator pedal. The DVOM will indi-
cate “0” voltage if the solenoid contacts are closed.
(c) If “0” voltage is not indicated while the accelerator
pedal is pressed, replace the solenoid.
TESTING CHARGING CIRCUIT
Tool List
Qty.
DVOM ..........................................................................1
To prevent the possibility of injury resulting
from vehicle inadvertently starting, the drive
belt must be removed or both rear wheels
raised (see procedure in Section “B”).
The charging circuit consists of a starter/generator, volt-
age regulator and battery (Ref. Fig. 1). The solenoid
must be functional in order to start the vehicle, but is not
considered part of the charging circuit.
1. If the battery charge is inadequate (less than 11 VDC),
proceed as follows:
(a) Check the battery voltage and inspect for loose or
corroded terminal posts and connections. Check
electrolyte level.
b) Check charging circuit component terminals for
proper, clean, tight connections.
c) Check for charging voltage as follows:
1) Raise the vehicle (see procedure in Section B)
so that both rear wheels are free to rotate.
2) With the engine off, measure the voltage at the
battery’s terminals by placing the negative (-)
probe on the negative (-) post and the positive
(+) probe on the positive (+) post of the battery.
Note the reading.
3) Attach the DC voltmeter across the regulator’s
red and black leads.
4) Start the engine and accelerate to governed
speed.
5) The meter should read higher than before start-
ing the engine. In a reasonable amount of time,
the reading should settle between 14 and 15
volts, indicating the regulator is functioning
properly.
6) If no increase over battery voltage is observed,
there is a malfunction in the charging circuit.
7) If the reading is
above
15 volts, check to
assure the wiring harness and generator field
winding (green lead) is not grounded. If it is not,
replace the regulator.
8) If the reading is
below
14 volts, disconnect the
regulator’s green field wire from the system
harness. Temporarily connect the green field
