CAUTION
1. A2-330/A2-336 regulators are flat-temperature compen-
sated and are factory-set at lowest setting to accommodate
8D batteries. For other batteries:
a. Remove regulator from housing and change position
on voltage selector switch. See Table 1.
b. Re-install regulator on drive end housing, and torque
mounting screws to 8.5 Nm/75 lb. in.

A2-346 regulator is flat-temperature compensated.
A2-346 28 V regulator can be used with or
without A9-4036 temperature-voltage sense/
J1939 harness from the vehicle.
• When A9-4036 temperature-voltage sense/
J1939 harness is not connected, regulator
will operate in fixed voltage setting deter-
mined by the select switch position on the
bottom of the regulator. See column 2 in
Table 2.
• When A9-4036 temperature-voltage sense/
J1939 harness is connected, regulator will
automatically optimize the charge voltage
for battery type based on temperature.
See column 3 in Table 2 and select switch
position based on battery type.
Regulator is factory-set to Position 1. To change, remove
regulator, turn regulator over, and select appropriate
switch position (see NOTICE above and Table 2).
Re-install regulator on alternator. Torque screws to
8.5 Nm/75 lb in.
