A2-337 Regulator

with A9-4011 Temperature Sense Lead

for C626 Alternator

Installation Instructions

1. Install regulator on alternator, using mounting

hardware furnished with regulator. Torque

screws to 8.5 Nm/75 lb. in.

2. Plug alternator-to-regulator harness securely into

regulator.

3. If A9-4011 temperature sense lead is used, see

Figure 1:

a) Connect twin lead ends of A9-4011 tempera-

ture sense lead:

• one to regulator T terminal, using hard-

ware furnished, torque terminal nut to

4.5 Nm/40 lb. in.

• the other to one mounting bolt. Retorque

to 8.5 Nm/75 lb. in.

b) Connect single sense lead ring terminal to

B– terminal on battery as shown in Figure 1.

Tighten hardware securely.

c) Coil up any unused sense lead and use cable

ties every 12-14 inches to securely support

temperature sense lead between regulator

and battery.

4. Complete remaining connections to regulator, if

required, as shown in Figure 1.

• Connect P terminal to tachometer or relay.

P terminal taps AC voltage, typically half the

charge voltage. Torque M6 terminal nut on

regulator to 4.5 Nm/ 40 lb. in.

• Connect D+ terminal to multiplex controller:

D+ terminal provides 28 VDC voltage output

to multiplex controller. When connecting D+

terminal to controller through a relay, the

relay coil must be diode protected and rated

for proper voltage. Torque M5 terminal nut

on regulator to 4.5 Nm/40 lb. in.

5. When the A9-4011 temperature sense lead is not

in use, the regulator will operate at 27.5 V.

6. When A9-4011 temperature sense lead is in use,

the lead senses the ambient temperature within

the battery box and regulator will adjust charge

voltage based on battery temperature—the higher

the battery temperature, the lower the charge

voltage.
