Low Voltage Module
Purpose
The illumination of the battery light on the dash
indicates the battery voltage is too low. This is
sensored through the low voltage module.
Location
The low voltage module is located under the front
hood, on the lower end of the front side of the firewall of
the tractor (Figure 227).

How It Works
The low voltage module (Figure 228) is a voltage
comparator, checking the charge voltage from the
engine regulator/rectifier system. If the charge voltage
is less than 11.3 volts D.C., the low voltage module
senses this and activates the indicator lamp on the
dash which will light until the voltage is over 12 volts
D.C.
