TESTING ELECTRICAL SYSTEM
Before electrical tests of these switches are made,
make sure mechanical adjustements of the
acutating mechanisms are correct.
BRAKE/START AND BRAKE/CRUISE
SWITCHES
To test switch, connect an ohm meter between
the C and D terminals (See below) and depress
plunger. Meter should indicate open (infinite
resistance) to closed (zero resistance).
Connect the meter between the A and B
terminals, and deperess the plunger. The meter

should switch from closed (zero resistance) to open
(infinite resistance).
ATIACHMENT DRIVE SWITCH
When switch is in the down (OFF) position, check
continuity between the middle terminal and top
terminals. Resistance should be zero.
When switch is in the up (ON) position, check
continuity between the middle and bottom
terminals. Resistance should be zero. Check both
halves of the switch.
