Proper use of the Ohm Meter for an accurate Reading. If you are using a cheapie Harbor Fright Ohm Meter after you set it you need to put the 2 Wire Probes together and measure the resistance in the Probe Wires.
When you have that reading you should subtract that from the reading you get from the Glow Plugs.

A high when you put the Wire Probe together on a High Quality Meter it will show no resistance.

Also concerning testing hot or cold Glow Plugs I thought they were always tested cold.
