Whilst I know how a relay works and can test for bad earths etc., but beyond that…. So, please help but answer in children’s terms!
As the old quote goes: “It is better to be thought an idiot, than to open one’s mouth and confirm it”.
So, excuse my ignorance below.
As far as I can tell, if you have resistors in parallel, you have an increase in current. Is this why (I believe) there is a second resistor in parallel with the air temp sensor?
If I am right, please explain something. If you have a 10 k ohm thermistor and you add a 5 k ohm resistor in parallel to get about 3.3 k ohm of total resistance, why not just use a 3.3 k ohm thermistor?
Are they made? Does using parallel resistors do something different to the current?
Laugh if you feel the need, but it plays with my head.
