How It Works
Coming straight from the 120-volt outlet, the current is
half-positive and half-negative. The rectifier charger
polarity “filters” out the negative half of the wave to give
you a direct current (Figure 154).

Rectifier Troubleshooting
1. Disconnect the rectifier assembly from the wiring
harness.
2. Check continuity between the terminals (two side
by side terminals) on one side of the rectifier with
a Volt-Ohmmeter (Figure 155). Note the results.
Figure 155 1352-13
3. Reverse the VOM leads and recheck the same
two terminals. Note the results. You should have
found continuity in one direction, but not the other.
If not, replace the rectifier. This test must be
performed on all four sides of the rectifier.
