Well, that did go well and the -ve was on the 3 wire side.
QUESTION.................When you say,"...I do it all the time." is that because they are:
a...detaching all the time? or
b... failing and requiring replacement all the time? or
c... you are upgrading the emitter?
and if B where are replacements sourced?
Once again my thanks, especially for the Youtube link
which really gave me confidence.
