Converter In-Rush Thermistors etc, UPDATE -4
UPDATE on 17 Nov, Update 2 on 22 Nov, Update 3 on 16 Jan 14, Update 4 on 19 Oct 14. --------------- In a recent thread there was mention of how you can wreck your gizmo (in my case a converter) ...

I never got an answer to this post, to see if there is any R left or not. ( I thought if it heats up that means there is some R)

While trying to get the meter probe/clamps onto the thermistor's legs to measure R, some more pieces got knocked/fell off the thermistor.
So now instead of half a thermistor, I am down to one third. I plugged it in and it is showing 14.78v (where I had it set)at the DC output, no load.
I have never tried to measure ohms before. I set the meter at 200 (other choices are 2000, 20K, 200K, 2000K, and 20M), put probes at each thermistor leg (converter on) and the dial showed between 26.x and 30.x going back and forth. Not a clue what that means.
Spec for this thermistor (when whole!) is
5.0 ohm
R at 100% max current- 0.03 ohm
R at 50% max current- 0.08 ohm
Max steady state current up to 65C 20.00A
