Kawasaki Z1000SX - Service manual > Relay Box

The relay box [A] has relays and diodes. The relays and diodes can not be removed.

Relay Box Removal

NOTICE Never drop the relay box especially on a hard surface.

Such a shock to the relay box can damage it.

• Remove the rear fender from the battery case and rear frame (see Flap and Rear Fender Removal in the Frame chapter).
• Disconnect:
  Connectors [A]
• Remove:
  Relay Box [B]

Relay Circuit Inspection

• Remove the relay box (see Relay Box Removal).
• Check conductivity of the following numbered terminals by connecting the hand tester and one 12 V battery to the relay box as shown (see Relay Box Internal Circuit in this section).

  If the tester does not read as specified, replace the relay box.

Relay Circuit Inspection (with the battery disconnected)

*: The actual reading varies with the hand tester used.

Relay Circuit Inspection (with the battery connected)

(+): Apply positive lead.
(-): Apply negative lead.

Diode Circuit Inspection

• Remove the relay box (see Relay Box Removal).
• Check conductivity of the following pairs of terminals (see Relay Box Internal Circuit in this section).

Diode Circuit Inspection

The resistance should be low in one direction and more than ten times as much in the other direction. If any diode shows low or high in both directions, the diode is defective and the relay box must be replaced.

NOTE

• The actual meter reading varies with the meter or tester used and the individual diodes, but generally speaking, the lower reading should be from zero to one half the scale.
