Hi KL7AJ! This is my first experience talking to someone in the North Pole!! Thanks for your suggestion. Following the replacement of the power cables it seems to be behaving itself right now. If I have any further problems I'll explore the time lag breaker thing, but I wonder if this device might be peculiar to household supplies that are not 240v 50Hz?You might want to see if you have the proper time lag breaker installed. These are especially designed for motor start-up conditions.
