(2) Shows direction and amplitude of current flow. Recommended for low output alternators and low electrical loads. Electrical connection: Alternator/Regulator output goes to terminal marked “S.” Terminal marked “I” goes to battery.
(3) Operates on any DC voltage from 8V to 32V negative ground. Prevents over or underservicing when mileage does not give a true indication of engine use - where power take-offs are used.
Voltmeters monitor battery conditions, rate of charge and discharge and regular setting or alternator belt-slippage. Voltmeters have only two terminals marked “G” and “I” - apply: +12v DC to “I” and ground “G” on negative ground system. Color coded.
