TRAVEL CIRCUIT - Continued
Clutches do not pull in
Track switches in travel position.
Voltage checks: (LH side)
(1) 36 to 3 - defective LH travel switch
(2) Relay R6 should be energized - if not, check for bad relay coil or socket, or lack of continuity from 39 to 3.
(3) 21 to 3 - defective R6 relay contact or socket
(4) Check for defective clutch coil - should have 3.5 ohm resistance for standard torque and 1 ohm resistance for
hi-torque
Voltage checks: (RH side)
(1)
37 to 3 - defective RH travel switch
(2)
Relay R7 should be energized - if not, check for faulty relay, socket, or lack of continuity from 39 to 3
(3)
23 to 3 - defective R7 relay contact or socket
(4)
Check for defective clutch coil - should have 3.5 ohm resistance
