CAUTION: DISCONNECT BOTH AC INPUT AND DC OUTPUT CORDS FROM ALL
POWER SOURCES BEFORE YOU PERFORM THIS TEST.
Remove the Phillips screws that retain the cover, and then remove the cover. Locate the
transformer output leads that attach to the rectifier/diode assembly at the rear of the case as
shown in Figure 8, then remove the 11/32 nuts that retain these leads. Carefully reposition
these leads so that they are at least 1/4 inch away from any objects near them as shown in
Figure 8.

DANGER: HAZARD OF ELECTRICAL SHOCK. ONLY QUALIFIED PERSONNEL WHO
ARE KNOWLEDGABLE IN ELECTRICAL SAFETY PRECAUTIONS ARE TO TEST
EQUIPMENT WHILE ENERGIZED!
A successful test will require that you apply AC power to the transformer to measure its output.
Bypass the electronic charge controller as described in SECTION 7A, Figure 7E, verifying that
the terminals are making electrically sound connections. Attach the clips of the meter to the
transformer output leads as shown in Figure 8. Adjust your meter to measure the maximum
AC voltage anticipated from the transformer – 97 volts. For your personal safety insure that
the meter clips touch only the transformer leads, and that the relay jumper wire is not near any
electrically conductive components. Connect the AC input cord to a live outlet.
If the AC line fuse or circuit breaker blows, the transformer is shorted internally and must be
replaced. If this does not occur, check the transformer secondary voltage and record the
reading you obtain. Compare this reading to the output voltage listed in the table. If the
measured voltages are substantially lower than those shown, the transformer is either shorted
internally or open and must be replaced.
