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]).
35. TRANSMISSION AND CLUTCH.
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]).
