2. Test diode(s).
Test in the following sequence:
1. Set meter to DC Output test. See Figure
11.
2. Attach RED test lead clip to DC output
terminal connector ([A] Fig. 14).
Fig. 14
3. Attach BLACK test lead clip to positive (+)
battery terminal ([B] Fig. 14).
4. Start engine.
Output should be 2 to 4 amps DC @ 3600 RPM.
Output will vary with battery voltage. If battery
voltage is at its maximum, output will be
approximately 2 amps.
If no or low output is found:
• Test diode.
Diode Test
In the Diode Test, the multim eter will display
forward voltage drop across the diode(s) . If
voltage drop is
less than 0. 7
once and display the voltage drop. A continuous
tone indicates continuity (shorted diode) An
incomplete circuit (open diode) will be displayed
as .
OL
1. Set meter to Diode Test. See Figure 9.
2. Attach RED test lead ([A] Fig. 15) clip to
point (B) and BLACK test lead (C) clip to
point ([D] Fig. 15). It may be necessary to
pierce wire with a pin as shown.
volts, meter will beep
Fig. 15
If meter beeps once:
• Diode is OK.
If meter makes a continuous tone :
• Diode is shorted.
• Replace the diode.
If meter displays
OL:
• Proceed to step 3.
3. Reverse test leads.
If meter beeps once:
• Diode is installed backwards.
If meter still displays
OL:
• Diode is open.
• Replace the diode.
NOTE
: Replacement diode harnesses are
available. Use Rosin Core solder to install new
harness. Use shrink tubing or tape on all
connections. Do not use crimp connectors.
