Beretta V6-173 2.8L (1989)
Fuel Gauge: Testing and Inspection
Test C: Fuel Tank Shows "E"
Disconnect connector C200 and turn the ignition switch to the "RUN" position.
1. If the display now reads F, the wiring is good. Install a new fuel gauge sender.
2. If the display still reads E, check the PNK (30) wire. If that wire is not shorted, replace the instrument cluster.
