9-5 Aero (9600) L4-2.3L Turbo (B235) HO (2000)
This method is used to ascertain whether the voltage drop in a wiring harness or across a component, etc., is too high.
1
Connect the voltmeter positive lead to that part of the cable or component closest to the power supply.
2
Connect the voltmeter negative lead step by step towards the load (item of electrical equipment), which should be switched on.
3
When the circuit is activated, i.e. when current flows through it, the voltmeter will show the difference in voltage between the two measurement
points.
^
A circuit in perfect working order should not show a voltage drop of more than about 1 V.
^
In simple circuits or connectors, the voltage drop ought not to exceed about 0.5 V.
