6 Continuity of fuse on P.C.B. Ass’y

• Check for continuity using a multimeter

as shown in Fig. 19.

Method Used to Replace Fuse on PCB

Ass’y

1. Remove the PCB Ass’y from the electri-

cal component box.

2. Remove the fuse from PCB Ass’y using

pliers while heating the soldered leads

on the back side of the PCB Ass’y with

a soldering iron (30W or 60W). (Fig. 20)

3. For replacement, insert a fuse of the

same rating to the intended position and

solder it.

(Allow time to radiate heat during sol-

dering so that the fuse does not melt.)

When replacing the

fuse, be sure not to

break down the varis-

tor.
