ELECTRICAL
5-14 Rev. 000 TX525 Service Manual
If the circuit the fuse is protecting draws too much
current, the metal conductor in the fuse melts in two,
opening the circuit.
A failed fuse will often be discolored or melted. Please
note that not all fuse failures are easy to see. A fuse
can be checked with a continuity tester if there is doubt.
If there is no continuity between the fuse terminals,
replace the fuse, even if it appears good.
Fusible Link
Purpose
How It Works
Testing
The fusible link is a specially fabricated wire that acts as
a high-current fuse to protect the circuit from excessive
current draw.
Location
There are 2 fusible links on the TX525.
Shut down solenoid (Fig. 0824) .8mm fusible link:

Fuses
Purpose
Location
Fuses are used in the circuits to limit damage in the
event of excessive current ow. If a fuse fails, look for a
short circuit, a corroded/poor connection, or any com-
ponent that appears to have been overheated. A failed
fuse is a sign of a problem in that circuit.
Fuses are located under the hood, mounted to the tower
assembly (Fig. 0823).
