Thanks for your reply. I'm assuming that I need to turn switch on to see if display/diagnostic readings show, and once they are shown (if they are), then I should immediately turn the switch off. Am I anywhere near correct?Install the fuse, jump the legs together and see if the display comes on and gives you diagnostic readings.
Leave the switch in the Off position until you get the new thermistor installed.
When the new thermistor comes in, install it and you should be good to go if the display readings are good.
