When there's too much leakage
current …
AC/DC Fails
Where applicable, check the AC/DC adapter and its cable. 
Replace a new one if any portion is defective.
Chassis Fails
Check the ground on the power cord and plug for continuity. 
Ensure the ground is not broken, frayed, or intermittent. Replace 
any defective part.
Where applicable, tighten all grounds. Ensure star washers are 
under all ground studs.
Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet; verify it is grounded and is free of other 
wiring abnormalities. Notify the user or owner to correct any 
deviations. As a work around, check the other outlets to see if 
they could be used instead.
NOTE:  No outlet tester can detect the condition where the white neutral 
wire and the green grounding wire are reversed. If later tests 
indicate high leakage currents, this should be suspected as a 
possible cause and the outlet wiring should be visually 
inspected. If reversed wiring is observed, it is the customers 
responsibility to have the condition corrected by qualified 
personnel.
