1. Fusible crossing point

2. Additional safety lock

3. Connecting block

4. IOD socket

5. Safety lock of a special purpose

Crossing points (wire pieces with calibrated by the section and length) as a rule protect silnotochny chains (except a starter) and connect to a positive pole of the battery.

For replacement get a crossing point from the socket and insert new, having convinced that in nominal parameters the new crossing point in accuracy corresponds to replaced.
