Does your power outlet have three holes and your power cord three       wires and prongs?              2. Make sure the round prong on the cord is connected to the ground on       the unit. This requires a simple continuity tester or an ohm meter       connected between the round prong and the chassis of the unit. The unit       needs to be unplugged when you conduct this test.              3. Is the round hole on the power outlet connected to earth ground?       This can be tested in a similar fashion, but will require you know where       to find a good earth ground.              4. If both of these tests are good, then your unit is well grounded and       this is not the problem.              5. If you are using a two wire cord or a two hole outlet, you likely       have a ground loop and this is causing your problem. You MUST have good       grounding.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
