If the above steps did not correct the problem, change the
main harness.
1.9 Main Harness
1.8 Circuit Breaker Test
To check the circuit breaker set the meter to ohms and
measure the resistance across the circuit breaker as shown
in (figure A1.8.1). If the meter reads more than 1 ohm,
then change the circuit breaker, otherwise proceed to next
step.
A1.8.1
If the meter reads more than 1 ohm, then change the circuit breaker.
If the previous steps did not correct the problem, change the main harness.
Check that the battery fuse is in good condition. With the
batteries disconnected remove the fuse cap, inspect the
fuse to see if the fuse is blown. To make sure the fuse is
not blown, set the meter to ohms and measure the resist-
ance across the fuse. see (figure A1.7.1). If the meter
reads more than one ohm, change the fuse, or else pro-
ceed to the next step.
1.7 Battery Fuse
A1.7.1
If the meter reads more than one ohm, change the Battery fuse.
1.6 Battery Wire Harness
Check that the battery wire harness has the polarity cor-
rect. Set the meter to dc volts and measure the connector
with the red lead on the red wire contact (top of the con-
nector) and the black lead on the black wire contact (bot-
tom of the connector) as shown in (figure A1.6.1). If both
battery wire harnesses have full voltage and correct polari-
ty, then proceed to step 1.8. If voltage is absent proceed to
step 1.7. If polarity is reversed correct battery wiring.
A1.6.1
If polarity is reversed correct battery wiring.
