DESCRIPTIONS OF ALTERNATOR TERMINALS (See illustrations):
“BAT” Output (+) - Output terminal, connects to the Positive (BAT) Battery terminal to charge the batteries.
“P” Phase (Relay) - Relay terminal carries half system voltage and may be used for certain types of control relays, charge indicators,
tachometers or similar devices. The current draw should not exceed four (4) amperes. Notice! Do not connect the remote sense lead
to this terminal.
“L” Indicator Lamp - Indicator Lamp terminal can take up to 1 Amp Lamp Current.
Field Monitor - External Field Monitor is only used for diagnostics.
“GRD” Screw - Grounds the alternator. A Ground lead is strongly recommended for optimum performance.
“Remote Sense™” Terminal – Remote Voltage Sense (if equipped) used to more accurately control system voltage by monitoring
actual voltage at Battery Terminal or Junction Block. Notice!
Be careful not to ground the lead’s open end, because the line is always
live “hot”.
