=b. Lights Burn Dim but Brighten Up Considerably When Engine Is Accelerated.= Test battery with hydrometer. If it is not fully charged, replace (par. 113). Remedy defective wiring, connections, and switches in circuit (fig. 73). If the battery runs down again after a short period of operation, have the generator output increased (refer to a higher echelon).
=c. Lights Exceed Normal Brilliancy When Accelerating Engine.= Examine battery: if defective, replace (par. 113). Remedy faulty wiring and connections (fig. 73). Do not forget the ground connection of the lamp body.
=d. Blackout Stop Lamp and/or Service Stop Lamp Fail to Light.= If the unit is burned out, replace it (par. 115). If the brake pedal is not operating switch, remedy the faulty operation. Remedy all faulty wiring and connections (fig. 73).
=e. Horn Does Not Sound When Ignition and Light Switch Is Turned On and Horn Button Is Pressed.= Test battery by turning on lights. If lights are dim, replace battery (par. 113). Remedy defective wiring and connections (fig. 73). If the horn does not respond to adjustment, replace (par. 117).
=a.= Need for attention to clutch and controls is indicated by clutch slipping under load or dragging (transmission gears will shift hard and clash) when in disengaged position. In either case, the first thing to be checked is adjustment of controls; this being the attention usually needed. Indication that gear shifter controls are in need of adjustment is when transmission gears “jump” out of engagement when accelerating vehicle or when under heavy pull. CAUTION: _This warning must not be disregarded._
(1) CLUTCH SLIPS WHEN FULLY ENGAGED. Adjust clutch control (par. 48). Adjust clutch spring tension (par. 48). If the clutch still slips, replace either the disks, springs, or both (par. 48).
(2) CLUTCH DRAGS WHEN FULLY DISENGAGED. Adjust control (par. 48). Adjust spring tension (par. 48).
(3) CLUTCH RATTLES WHEN IN DISENGAGED POSITION, ENGINE IDLING. In this case, the clutch probably was not properly assembled. Refer to paragraph 51 =a=.
(4) TRANSMISSION “JUMPS” OUT OF GEAR UPON ACCELERATING VEHICLE, OR WHEN UNDER HEAVY PULL. Adjust shifter lever control linkage (par. 54).
(5) TRANSMISSION GEARS SHIFT HARD OR CLASH WHEN CLUTCH IS FULLY DISENGAGED. Adjust clutch control linkage and spring tension (par. 48). Make sure the transmission mounting bolts and units are tight (pars. 57 and 58). Drain and fill transmission with correct lubricant (fig. 10). If the above methods fail to cure the symptom, refer to a higher authority.
