LOW VOLTAGE SENSOR FROM RON FRANCIS TRIGGERS A WARNING LIGHT
|
The RON FRANCIS WIRING Low Voltage sensor is designed for use with virtually any alternator to activate a warning light as soon as the voltage drops a hair below 11 volts. The sensor can be used in conjunction with your voltmeter or ammeter, or all by itself.
One-wire alternators, unfortunately, don’t have the wiring for an "idiot light” to tell you there’s a serious problem. With this device in the system, a warning light is triggered that will attract your attention immediately. It’s much more noticeable than a gauge with a slowly dropping needle, which may go completely unnoticed.
The benefit to running this Low Voltage Sensor is that your warning light tells you something has reached the danger point before it’s too late. If voltage drops too far, fuel-injected engines will begin to misfire and most electronic circuits relying on 12 volts (such as cooling fans) may also shut down if there isn’t at least 10 volts for them to operate.
Hookup is fast and simple –one wire to a keyed 12-volt source, another to a ground, and one to an indicator light. You can use an LED, a small indicator like those sold by RON FRANCIS WIRING, or just connect it to the existing factory idiot light in your classic car. Price for the Low Voltage Sensor is just $18.95.
