See step 3a

A9-4036 temperature-voltage sense/J1939 harness can be used with A2-341, A2-342, A2-343,

A2-346, and A2-351 regulators.

• When A9-4036 temperature-voltage sense/J1939 harness is not connected, regulator will operate

in fixed voltage setting determined by the select switch position on the bottom of the regulator.

See separate instructions with regulator.

• 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 2 in Table 1 and

select switch position based on battery type.

NOTICE

1. Remove hardware from regulator, turn regulator over

and select appropriate switch position (See NOTICE

above and Table 1 and Figure 1).

2. Reinstall regulator on alternator. Use screws and

washers (if supplied). On alternator, torque regulator

mounting screws to 8.5 Nm/75 lb. in. Make sure

6-socket harness is securely connected to regulator.

3. Install A9-4036 temperature-voltage sense/J1939

harness to regulator:

a. Remove cap from regulator and plug harness

connector into 10-pin connector.

b. Harness length is 182 inches, enough to reach

battery compartment in most vehicles. Unused

harness length should be coiled up. Use cable ties

every 12-14 inches to securely support harness

between regulator and battery compartment. If

harness length must be shortened:

1) Black wire—Do not shorten unless absolutely

necessary. If necessary, cut off first 6 inches on

terminal end and save cut piece to reattach.

Cut length off of remaining black wire.

Crimp and solder two ends and seal with

insulatable butt splice.

2) Red wire—cut to desired length and use

terminal to connect.

c. Attach terminal from black wire in A9-4036

harness to battery negative post and terminal

from red wire to 28 V battery positive post.

If using J1939 connector on harness, connect

as indicated by vehicle manufacturer.

4. Verify all electrical and mechanical connections to

regulator are tight.

See step 3d
