7.1.8 Filter Capacitors and Ground Wire
We can install the filter caps now that we have most of the components installed
on the board.
Insert the three (3) filter capacitors in their locations as indicated on the board.
These capacitors are polarized. Be careful to install them by inserting
the positive lead (the longer one) into the square pad and the negative
lead (as indicated by the downward arrow and “-“ symbol) in the round
pad.
Insert the ground wire that was removed from the stock EVJ circuit board in the
ground pad indicated on the Baby Will circuit board.
Solder and trim the leads.
7.1.9 Jumper Wires
Three jumper wires need to be installed. J1 and J2 are used to connect the
power rail across the heater traces. The third jumper is used to bypass the
standby switch.
Install, solder and trim the jumper wires as shown.
