If thats the case and your genuinely are missing sat.i have done twice replace them 2 now got to be some thing else
what makes reed switch blow
How can moonbase say its the jack when he has no hands on experience of your equipment, he is giving his opinion on what it could be. You need to test your equipment but how you test you type of equipment i'm unsure. Maybe test the motor to see if its going short circuit. I'm guessing there should be no continuity between cable in and casing of the motor.so u saying its the jack then
its got t be the rssd switch if not the motor gos back its unger garan
