If you hold the test leads of an ohm meter together the resistance should go to zero ohms or very close. If it doesn't you're ohm meter is malfunctioning. ANSWER: Actually that is the first thing to do. It should show a zero reading If not the meter needs calibration adjustment. Otherwise the reading will be off by the that amount as true value.
The total resistance would be 40 ohm.
1st make sure the power is turned offDisconnect one lead on primary side of transformer and using an ohm meter check for continuity. You will probably get a low ohm reading if you get no reading the windings are broken and transformer is no good2nd test using ohm meter again check for winding to ground you should get no reading. If you get a ohm value the transformer is shorted to groundRepeat these tests on secondary sideWith power on and fuse removed with a voltage meter check for power on secondary sideIf it is okay turn off power and install fuseIf fuse blows again check for shorts in circuitRemember to be careful when power is turned on
To calculate the ohm reading of a 4500-watt baseboard heater, you would need to know the voltage it operates at. You can use the formula Ohms = (Voltage x Voltage) / Watts to find the resistance in ohms. For example, if the heater operates at 240 volts, the ohm reading would be approximately 12.8 ohms.
50 ohms...!

There is no normal ohm reading. You have to test the output voltage with the engine running. Should switch between .1V and .9V.

If the thermostat is open, the ohm reading will be O/L.

With a mutimeter test between each lead (usually yellow in color), the reading should be approximately one (1) ohm. or close.
4.12A. V=IR
The reading will vary from empty to full.
