Then there's these 3: SSI yellow label 12469158-1 uses Kds or Nartron temp sensor 12469158-2.
Its riveted together...not screws like the others on upper posts.
The Prestolite and Ametek are 12446779 and riveted also......these two use the Nartron
temp sensor 12338772 only.

Looks like great info. I will attempt to gain enough knowledge to digest more of it!

Hood parts arrived in great order, and just as advertised. Thank you!

KDS Smart Box CR-2700
Can someone take the cover off their KDS smartbox and measure this resistor for me? I know it is a lot to ask, but mine is burnt and these things are $500+. I need to replace but I have no way of knowing its resistance value.

Does anyone have the part number for the mosfets in the KDS Smart Start Systems (S3) box? I know the KDS black boxes use 75344G and I can see on what remains of the mosfets in my S3 box they have the 75344 but the numbers on top are different. The S3 box has 1H01AB above 75344 but the ones in the KDS black box say NF39AD over 75344G. Do all the boxes use the same mosfets? Just wanted to make sure I was ordering the right stuff before I ordered new mosfets.

100 Ohms. Not trying to be flip... But not like old tube days down at the drug store changing dead TV tubes. There are 1000's of semi conductors in that over engineered box. (not a fan of the box) Might work and save a buck. Good luck shot-gunning parts that are fried.

Might want to take a look at the Zener in front of the heatsink left of power FET AND the ribbon cable has a bite taken out of it.

When the smoke comes out... things quit working.
