AM503B and A6302 Probe - Error 588 - No DC Output Signal

I recently bought a AM503B amp and A6302 probe from ebay. It has been found that the A6302 probe is bad and will elicit a 588 error from known working AM503B amps. The probe will not degauss. Degaussing is what causes the error. The AC amp function will provide an output signal but the DC function does not provide an output other than a positive DC offset that cannot be corrected by the amp trimmer pot. Does anybody know if this is an indication that the hall effect sensor is bad?

Thanks,

Dave

As in my previous reply, check for a broken wire in the connector.
