Test Procedures
TEST PROCEDURE 27 – Voltage Limiter
See General Warnings on page 1-1.
NOTE: This is a diode test.
The voltage limiter is a diode. Diodes are designed to conduct current in one direction only. See following NOTE.
NOTE: If the voltage limiter conducts current in both directions, the diode has failed closed. If the voltage limiter will
not conduct current in either direction, the diode has failed open.
1. If necessary, see Testing Basics on page 18-14.
2. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
3. Remove the cowl. See Cowl Removal, Section 4, Page 4-6.
4. Disconnect green wire from positive (+) terminal of voltage limiter and black wire from negative (-) terminal.
5. Using a multimeter on diode setting, test voltage limiter as shown (Figure 18-25, Page 18-42).
