High voltage Dart -67

The other thing about resistance, is, that it CHANGES often, with load, IE heating up, arcing, etc, so the problem can get worse. That is why I try and encourage more use of voltage checks and depend less on resistance checks. Plus, ohmeters get less and less accurate as resistance decreases.

There is a procedure sometimes called "the 4 wire method" which is basically turning the test area into a shunt and running current through it, then measuring the voltage drop and calculating the resistance

So even though the end answer is R, the method is still "voltage drop" LOL
