TEST 8 - dIOdE/RESISTOR
PROCEDURE:
1. Set volt meter to the diode test range.
2. Disconnect the six pin connector from the Voltage Regulator.
3. Disconnect Connector C1. See Page 17 for connector location.
4. Disconnect both wires from the Resistor (R1).
5. Connect the positive meter test lead to the top terminal of the
diode (D1). Connect the negative meter test lead to the bottom
of the diode (D1). See Figure 6-15. INFINITY or an open condi-
tion should be measured.

6. Connect the positive meter test lead to the bottom terminal of
the diode (D1). Connect the negative meter test lead to the top
of the diode (D1). Approximately 0.5 Volts should be measured.

7. Set volt meter to measure resistance.
8. Connect one meter test lead to the top terminal of the diode
(D1). Connect the other meter test lead to the ground terminal.
INFINITY or an open condition should be measured.
9. Connect one meter test lead to one terminal of the resistor
(R1). Connect the other meter lead to the remaining terminal of
resistor (R1). See Figure 6-17. Approximately 25 ohms should
be measured.
