Take a look at the schematic again. On the ignition switch, R2 goes to Thermostart. C goes to the starter.

And apparently there is an internal bridge between C and R1 while the key is at Start. So ... If you have the optional jumper wire (mine does) between R1 and R2, then you have 'heat while crank'.

Dang everybody must be rained in, to put such attention into this trivia. I'll get outside as soon as the fog burns off and it gets above 45 degrees. 'Freezing fog' is how NWS describes here at the moment. Yesterday after it cleared, I got out and backhoed out a dead tree from the orchard. For once, the radiator heat blown back felt good.

Let me be sure I'm understanding this clearly, when you Winston and California are saying "start position" you are saying all the way as in cranking the engine over.... right? not in run position? as in the first click to the right that only powers up the sytem,.......... if this were the case than someone may have my switch wired in wrong, and am wondering if once I have started the engine and let go of the switch to the run position if the TS is still activated and if this were the case then seems to me something would burn out by now, that being both the switch and the TS-right! Hmmmmm

Yes, my point exactly. I don't see how it can work either way.

It works when the switch is in crank position, does not work with switch in on postion.

to everyone fallowing this thread about the ignition switch, I found the ignition switch on my 1700 to have polarity on both run and at start position to the Tstart, My test meter isn't working at the time so I dont know the exact voltage so I used a test light, and get a dim light to the Tstart when switch is in run, although as I hold it on the Tstart terminal and attempt to crank the tractor the light gets very bright, so yes as the other more knowledgeable folks here have said the Tstart should only be working in the start position of this particular kind of switch that only turns to the right, I stand corrected, and will need to look further into why it has polarity in the run position, My apologies if caused any confusion about this subject

You could drive the TS from a pushbutton switch on the lower edge of the instrument panel. That is what the parts manual shows as 'early'.

I think this is why there is a rubber plug on the lower part of the panel.
