You can check the meter movement by applying momentarily, ohm meter
probes to the back terminals of the meter, watching to have proper
polarity. (many meters have a + molded into the black back case. Be
aware some ohm meters have positive on the black lead. You may want to
include a series high value resistor so as to not "bang" the meter
pointer by meter overloading.
If the meter deflects up scale with this very short momentary test, you
next have to check the connections from meter to the circuit board.
Particularly, check any signal diodes near the meter connection.
An open either inside the meter circuit or in the associated AVC
circuit, will cause no action from the S meter.
