model # pv-v4520. won't record. unit doesn't even record snow, because i tried recording over a recording. the record switch checks ok, my question is there voltage supposed to be on one leg of the switch. i measure .3 on both sides.no manual,just guessing,the switch should have voltage on one side? thanks for any help. al marquardt ampm@xxxxxxx Help make your TechAssist online repair tips database better!
