1. Be sure to turn the power off before wiring.
2. Be particularly careful where you route the
wires.
Keep them well away from the engine, and
exhaust pipe, etc.
Heat may damage the wires.
3. When connecting the ground lead, fasten
the ground lead (black) securely to a clean
metal plate on the car. (Figure 10)
If the set is insufficiently grounded, it may
not operate or there may be noise.
4. If the fuse should blow, check to see if the
wiring is correct.
If it is, replace the fuse with a new one with
the same amperage rating as the original.
5. To replace the fuse, remove the old fuse of
the power supply lead and insert the new
one (3A). (Figure 11)
After the connection, fix the lead by a clamp
or insulation tape for protection.
