Greater than 1 Megohm

A megohm meter is an insulation test instrument. If the project requires an insulation test to be done then this is what you should use. A "megger" will apply a DC voltage up to 1000 volts on the conductor to see if there is a breakdown in the insulation value.
Assuming the DMM is rated to test diodes (not all are), meaning that it presents more than forward drop voltage to the diode, a shorted diode will test nearly zero ohms, usually in both directions.
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
It depends on the transistor. Minimum base-emitter junction voltage can be as low as 0.6 volts for a silicon transistor, and as low as 0.2 volts for a germanium transistor.
Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. For example, a motor rated at 2,400 volts should have a minimum insulation resistance of 2.4 megohms.
A "Megger" (which is short for "Megohm meter") is an instrument which generates a very high DC voltage so as to be able to test the quality of insulation which should have a very high resistance that can only be measured in megohms.
The voltage reading on the TPS of a 1993 Transport 3800 should stay the same at idle as at full throttle. It should read between 13 and 14 all of the time.

Most fuel pumps should read about 9 volts, but I think I remember some reading about 5 volts. Why do you need to the voltage at the pump?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.

To test a doorbell transformer, follow these steps: Turn off power to the transformer at the circuit breaker. Use a multimeter to check the voltage output of the transformer. Connect the multimeter leads to the transformer's output terminals. Turn the power back on and check the voltage reading on the multimeter. The voltage should match the transformer's rated output voltage. If the voltage is significantly lower or higher, the transformer may be faulty and need to be replaced.
Volt meter should be in a 5 volt scale.
The purpose of testing a doorbell transformer is to ensure that it is functioning properly and providing the correct voltage for the doorbell system to work. This can be done effectively by using a multimeter to measure the voltage output of the transformer. Simply set the multimeter to the AC voltage setting, then touch the probes to the terminals of the transformer to get a reading. A properly functioning transformer should provide a voltage within the specified range for the doorbell system to operate correctly.
No but if the lights came out we cant have air
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
