David,
I don't mean the actuator wire is getting physically hot... All I mean by
the word 'hot' is that it obviously has current when the starting process is
going on (otherwise the relay wouldn't open). Nothing seems to be
malfunctioning... other than that the relay closes during the starting
process... if that is malfunctioning.
Sorry for the confusion.... WORDS!
Bill
