Power Relay CA1aF
Interlock System Power Relay
The power relay [CA1aF-12V-N-5] is one
part that makes up the interlock system, and
is controlled by activation of the main switch,
safety switch, traveling pedal proximity
switch, and seat switch.

Inspection of Power Relay
Remove the power relay.
The normal measured resistance between
relay terminals 1 and 2 is about 80 Ω.

Key switch
The key switch is located in the upper right of
the operation panel. Measurements must be
made with each cable disconnected from the
key switch. If electrical continuity exists
between the terminals in each key switch
position, the switch is considered to be normal.
If there is no electrical continuity between the
terminals for any of the key switch positions,
replace the key switch ass'y with a new one.
