6. Connect the BLACK lead of the AC input cord to the common (COM) terminal of the relay on
the electronic charge controller and the WHITE lead to the dual QD terminal (B) on the
controller as shown in Figures 13C and 13D. Connect either transformer primary lead to the
dual QD terminal (B), and the remaining primary lead to normally open (NO) terminal on the
relay. Support the terminal board on the controller when connecting these wires to prevent
damage to the circuit board.

CAUTION: BE SURE ALL CONNECTIONS ARE POSITIONED SO THEY DO NOT SHORT
TOGETHER OR TO GROUND.
7. Replace the charger cover and check the charger for proper operation as follows:
a. This unit only functions when both the AC input cord is connected to a live outlet and the
DC output plug is connected to the battery receptacle.
b. When the last of the two connections are made (either AC or DC), after a short delay (3-
5 seconds), the control relay will click, the transformer will hum, and the ammeter will
indicate charge current.
c. If your charger performs as above, it is ready for use, if not, refer to the wiring diagram
and check to be sure the charger is wired correctly. Always monitor the first charge
cycle to verify proper turn off.

ASSEMBLY
REPLACEMENT
The diode assembly should always be replaced as a complete assembly. A 3/8 inch, 5/16
inch, and 11/32 inch socket or nutdriver and a Phillips headed screwdriver are the tools
required for this replacement procedure. To replace the assembly, follow the step-by-step
procedures listed below.
DANGER: HAZARD OF ELECTRICAL SHOCK. DO NOT ATTEMPT TO SERVICE YOUR
CHARGER WHILE IT IS CONNECTED TO AN AC INPUT OUTLET OR TO THE BATTERY
RECEPTACLE. TURNING OFF THE CHARGER DOES NOT REDUCE THIS RISK!
