you can use the AVO meter
What kind of meter is this? Do you mean it's an Amp, Volt, Ohm meter? More commonly called DVM (Digital Volt Meter) or VOM (Volt Ohm Meter). DMM (Digital Multi-Meter).

Have you any recommendations on how to use such a meter? What to look for? What a reading may mean? What setting to use? There's a bit more to knowing how to use a meter than just "you can use the AVO meter".

I, like others, suspect it's probably a capacitor. Checking a capacitor "In Circuit" can be tricky. If you have a loose capacitor laying around, you can learn how to read a capacitor by simply setting the VOM to ohms and then touch the test leads to the capacitor leads. The resistance should continually increase as long as you hold the test leads on the cap leads. Then switch the leads around so that you're testing the cap in the opposite way. The resistance should drop until it reaches and crosses zero and begin going up again. What's going on is you are using the meter to apply a charge to the capacitor. As its charge goes up its resistance also goes up. This is a good test to know whether you have a capacitor or not.

Thanks, sir. I used VOM (Volt Ohm Meter) & DMM (Digital Multi-Meter) to test the work of this component.
