Locate the microfuses on printed circuit
boardB. The microfuses are very small.
I/O microfuses

Use a multimeter to check microfuse 1A (the
main output microfuse): With the multimeter
in resistance mode, touch the metal tips of
the testing leads to the metal ends of the
microfuse. If the resistance displayed does not
change (thus remaining at a 100% resistance
state), then the microfuse is blown. If a small
resistance is measured, then the microfuse is
good.

CAUTION
Avoid pinching or grasping the small tabs that hold
the microfuse; doing so can permanently damage the
microfuse holder.
If the microfuse is blown, use needle‑nose pliers
or a fine hemostat to remove the microfuse and
to reinstall a replacement microfuse.

hemostat tool

Visually inspect the other microfuses for a broken wire or a scorched cylinder that is brown or black in
color; these are signs of a blown microfuse.
NOTE: You can also use a multimeter to check the microfuses (same instructions as in step 3).

CAUTION
Avoid pinching or grasping the small tabs that hold the microfuse; doing so can permanently damage the
microfuse holder.
If a microfuse is blown, use needle‑nose pliers or a fine hemostat to remove the microfuse and to
reinstall a replacement microfuse.
