2. Verify no power units are installed.
3. Remove cover from control & distribution panel [Figure 2].
Figure 2 – Connections to Control & Distribution Panel
4. Verify rectifier cables are connected to
B1
,
B2
, and
B3
terminals [Figure 2].
Verify rectifier return ground cables are connected to
G1
,
G2
, and
G3
termi-
nals [Figure 2].
5. Verify at least one battery string is connected to control & distribution panel [in
battery compartment, make sure
STR( )
connector is connected to battery
string]. Condition DMM to measure DC volts. Measure battery string voltage at
BAT( )
test point and
PVR
test point: meter will indicate 50.00 V DC or more if
battery string is connected.
6. Unseat (but do not remove) AYK1 circuit pack [Figure 3]. Verify rectifier con-
trol cables are connected with connectors firmly seated in
J3
,
J2
, and
J1
sock-
ets [Figure 3].
