Troubleshooting: No Power (cont.)
Check Battery Wire Harness
Check that the battery wire harness has the
polarity correct. Set the meter to dc volts and
measure the connector with the red lead on the
+ terminal and the black lead on the negative
terminal as shown in (figure 1.6.1) If both the
battery wire harness have full voltage and correct
polarity, then proceed to circuit breaker test. If
the voltage is absent proceed to battery fuse test.
If the polarity is reversed correct battery wiring.
A1.6.1
Check that the battery fuse is in good condition.
With the batteries disconnected, set the meter
to ohms and measure the resistance across the
fuse. see (figure A1.7.1). If the meter reads more
than one ohm, change the wiring harness, or else
proceed to the next step.

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 above steps did not correct the problem,
change the main harness.
