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 have watched this and it is over my head, but it seems from previous posts by you experts that it might be possible to go through these steps for my converter. In fact some or all of it has already been posted maybe, but I am not able to pull it together.

We do know that the converter can do 103 DC amps at 15.5v DC output with 120v input (I have been using 15.2v setting on the voltage pot lately in the cold ambient temp 32F as being roughly equivalent to 14.8v at 80F)
It has 2400 uF capacitors (two 1,200- 250v).
So is there enough there to go through the linked steps for a recommended thermistor? If so would appreciate seeing the results posted, even if different people come up with different results it might get us (or at least me! ) somewhere closer to a correct answer.
Then we can compare that with the real answer next week when PowerMax gets back.
Thanks
