- Fellow Techs, I am currently testing another 4800VAC transformer that is presenting a hot chasis problem. I have not isolated the transformer from chasis as of yet to test . It is only connected to a

- Your hot chassis could just be a phantom voltage reading. IE there isn't any real current potential between the B- and chassis ground. Due to the very high impedance of the probe it shows a voltage p

- This chassis definitely is hot, it bites pretty good. Using a piece wire touching from chassis to another contact chassis point yields a pretty good spark. Mike-KK4MS a_borg@yahoo.com _______________

- To eliminate the transformer, take the transformers HV leads loose and measure one lead to meter, and meter to chassis ground using an ohm meter, leaving one transformer lead open. If you get a readi

- Here is what I suggest: 1) Completely disconnect the transformer. 2) Check all leads with with an ohmmeter to ground. 3) If the readings are not infinite, you have a problem. If they are, 4) Check al
