Refer to Pictorial 44 while you perform the
following steps.
QO Reposition the circuit board as shown in the
Pictorial.
(Route the black, blue, and red wires coming
from circuit board holes E, F and K toward the
left as shown. Then route the remaining wires
toward the right as shown.
() Refer to the inset drawing on the Pictorial and
install two cable ties around the wires coming
from the circuit board in the areas shown. Pull
the cable ties tight and cut off the excess tie.
CIRCUIT BOARD CHECKOUT
Carefully inspect the foil side of the circuit board for
Heathkit
the following most-commonly-made errors:
() Unsoldered connections.
() Poor solder connections.
() Solder bridges between foil patterns.
{) Protruding leads which could touch together or
the chassis when the circuit board is mounted
later.
Refer to the illustrations where parts were installed
as you make the following visual checks:
{)} Electrolytic capacitors for the correct position
of the positive (+) or negative (-) marked lead.
() _ Transistor for the proper installation.
() _ Bridge rectifier for the proper installation.
This completes the assembly of the meter circuit
board. Set it aside until itis called for ina step.
