6.16 Checking the Rotor Diodes<br />
See Graphic: wc_gr002461<br />
There are two diodes on the rotor assembly. The engine/generator<br />
assembly must be removed and the stator must be separated from the<br />
rotor to check the function of the diodes. When checking, be sure to<br />
check both diodes.<br />
6.16.1 Unsolder the two wires from the terminal end of each diode.<br />
6.16.2 Using the diode setting on the multimeter, measure the voltage across<br />
the diode terminal and the base of the diode. Reverse the leads of the<br />
meter and measure the voltage again. One of the readings should be<br />
between 0.4–0.5V. With the meter leads reversed, the other reading<br />
should be OL or a very large reading (for example, 2.0 MV).<br />
6.16.3 If your readings do not match those listed above, replace both diodes.<br />
Unscrew the diode to remove it.<br />
