Correct.
So key off and that wire disconnected, would be safe.
Should be infinate resistance. Should be no connection to ground. Follow?
If not, make the sketch and we'll work from there.
O.K. that was the condition when I got the 21.6 ohms measurement. Sorry I don't follow or understand what you mean by "infinite resistance" and no connection to ground. Does that mean in the above "safe" condition the ohms reading should actually be zero? I'll draw the sketch first thing tomorrow. Thanks for your input and patience. Have a good night!
