10. Inspect and test switches, connectors, relays, solenoid solid state devices, and wires of electrical/electronic circuits; determine necessary action. P-1.

          Many relays are located in the fusebox and can easily be removed, replaced, or tested from this location. The fuses are also ideal spots to check for voltage drops if the circuit is hard to access.  If an open is suspected in the circuit a multimeter can be used in place of the fuse for that circuit to check for the presence of current.
