Voltage Drop Test: Testing the Starter Circuit
WebPerform voltage drop tests on the battery cable terminals and connections to the battery posts, engine block, and starter terminal. Terminals and connections should be clean and tight-fitting with little or no discernible … 1 Blade-type fuses have test points on top, a good place to meter the voltage in a circuit. Try this: Meter both test points on the millivolt range, and read the voltage drop across the fuse. No voltage? Then there's no current flowing. 2 Never insert the meter probe into the female end of a wiring connector.
