In some cases you can test the power and ground signals to it and may be able to test any other ignition signals to it to verify these are present and if they are all found to be o.k. this usually indicates the cassette itself is at fault needing replaced.It may also take an oscilliscope to test it further.If you need info on testing the powers or grounds let me know and I will see what I can come up with here.
