Elec fault diagnosis

Guys you need to get away from trying to diagnose "resistance" faults with an "ohm meter". The meter only measures resistance to a very small current (a few milliamps) generated from it's internal battery. This is fine for measuring isolated components with a know resistance value (coils etc) but for fault diagnosis the most accurate method is to measure "input" and "output" voltage at the component you suspect to be faulty with everything switched on and connected.
