2. A normal capacitor will show continuity for a short time, and then
indicate 9M once the capacitor is charged.
3. A shorted capacitor will show continuous continuity.
4. An open capacitor will show constant 9M .
5. Resistance between each terminal and chassis should be infinite.
8.5. Magnetron
Continuity checks can only indicate an open filament or a shorted magnetron. To diagnose for
an open filament or shorted magnetron:
1. Isolate magnetron from the circuit by disconnecting the leads.
2. A continuity check across magnetron filament terminals should
indicate one ohm or less.
3. A continuity check between each filament terminal and magnetron
case should read open.
8.6. Variable power controller
- Isolate variable power switch from the circuit by disconnected 2
leads.
- In order to check if variable power controllor is operating normally,
follow the test procedures below.
