ELECTRICAL
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
If the engine will not run, but the starter will turn the
engine, proceed as follows:
1. Check for loose terminals, wires and connections.
2. Check for an electrical discharge through the spark
plug wire as follows: Using a spark plug that is known
good, and with a spark plug installed in each cylinder,
place on a clean grounded engine surface, (muffler,
cylinder, etc.). Turn over the engine with the starter.
Look for a blue electrical arc at the spark plug elec­
trode.
3. If there is either a weak arc or no arc, try a new spark
plug, then check the condition and the tightness of
the spark plug wires. Plug wires can be checked by
substituting them with good ones.
4. Replace the plugs if necessary. Gap the spark plug
.028" - .030" (.71 - .76 mm) using a wire type spark
plug gauge.
Testing the Ignition Coil
Set the meter to the ohms scale, measure the resistance
between both primary wire terminals and between the
secondary wires (Ref Fig. 3 on page K-5). A normal read­
ing would be: P and -): 3.7 - 5.2 Q and Second­
ary (A and B): 10 - 17 K Q. If any readings obtained are
out of the above ranges, replace the ignition coil.
Testing the Pulser Coil
Unplug the connector leading into the engine. Place the
(-) probe from the DVOM (set to the ohms scale) on the
red/white wire from the pulser coil, and the (+) probe on
the black wire also from the pulser coil. A reading of 19 -
21 Q should be observed. If the measurement obtained
is out of this range or if a reading of no continuity is dis­
played, replace the pulser coil. Make certain that the air
gap is correct. Set with a .032 feeler gauge. There is no
timing adjustment.

If the engine will
not turn over, proceed as following (Ref
Fig. 1 on page K-2):
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 (Q) scale. Detach wires. Place
positive (+) probe on one terminal and negative (-)
probe on the other terminal. The reading on the meter
should be "O" Q with the switch key in the 'ON' posi­
tion and a visual signal (00) 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 Q indicates a good limit
switch. A reading of greater than 2 ohms indi­
cates that the switch terminals should be
checked. A reading of infinity a visual signal (00)
indicates that the switch must be replaced. Con­
nect 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 po) probe on terminal
"B". The DVOM should indicate approximately
12 V.
b) Press the accelerator pedal. The DVOM will indi­
cate "O" voltage if the solenoid contacts are
closed.
c) If "O" voltage is not indicated while the accelerator
pedal is pressed, replace the solenoid.
