Voltmeter Operation (Digital Dash)
The voltmeter display shows the battery voltage. The voltmeter is connected to the PNK/BLK(39) wire and the BLK(150) wire.If the generator output is high, low or 0 volts, a box around the voltmeter ISO symbol flashes to indicate a problem with the charging system. The signal is sent to the cluster through the BRN(25) wire.
