Nron,

If you go to the page below and scroll down I think you'll find what you're looking for only it's in pdf files not drop down charts. lots of other info on that page also.

This is what happens when an Oilhead trys to help a gas guy out. Sorry I was not paying closer attention.

I hope the site I offered still proves to be helpful though

thermocouple dropout

I think you will find a normal t'couple read under load around 14/15 and a dropout of 2-4..I believe any dropout exceeding 4mv will indicate power unit has resistance
