Those kenwood avr units are touchy and badly designed, good luck with it.

I'm not sure about this kind of varistor. For a normal varistor you can use analog meter set to x 10 k ohm and test it either way and it should not have reading. If have readings mean the varistor is shorted.

Please advise me how can i test a varistor "SV03YS". This varistor is silicon symetrical type an looks-like as diode with cathode mark and loacated in an AVR unit (power supply).
I downloaded the datasheet of related varistor and the internal juction shows "3 diodes in series" connection.
Or advise me what is the equivalnet? in order to replace it. I susspect that is defective, but i'm not sure.
For your info while the AVR is at good working condition, at the anode applied 28vdc and at the cathode 42vdc, in accordance of service manual.

Best regards in advance for your kind assistance.
Dimitris

Set your analog meter to x 10k ohm and it should have no reading in either direction.
