Probe V6-182 3.0L (1990)
Fig. 11 Regulator Plug Voltage Test
Fig. 12 Testing Regulator S &/Or I Circuit. External Voltage Regulator (EVR)
1.
Disconnect regulator wiring plug, then install a suitable jumper wire between connector ``A'' and ``F'' terminals, Fig. 12.
2.
With the engine idling and negative voltmeter lead connected to battery ground, connect positive lead of voltmeter to S terminal and then to I
terminal of regulator wiring plug, Fig. 11. Voltage of S circuit should read approximately 1/2 of the I circuit. If voltage readings are as specified,
remove jumper wire, replace regulator and connect wiring plug.
3.
If no voltage is present, the wiring is at fault. Service the faulty circuit.
