ELECTRICAL Light Bulbs Headlight Replacement Do not use the Spare Battery A and B circuits or other circuits that are controlled by the LVD to power elec- tronic engine controls, ABS circuits, or safety/work-related lighting. Be- fore adding any device to the vehi- cle's electrical system, consult your nearest authorized dealer or read the contents of TMC RP-136. Fail- ure to do so may cause equipment damage or lead to personal injury. WARNING! WARNING! Optional HID headlights have high voltage circuits and should only be serviced by a trained technician.
At- tempting to service the HID ballast without proper training may result in severe electrical shock which could lead to death or personal injury. Turn the bulb lock ring counterclockwise and remove the bulb. Do not allow the glass of the new headlamp bulb to come into contact with anything. The glass could become contaminated and cause bulb failure. Reassemble in reverse order. NOTE 5 The determination of what cir- cuits/loads that were connected to the LVD was based upon the rec- ommendation from Technology and Maintenance Council (TMC) of the American Trucking Association. To review the recommended practice, see TMC RP-136. 5-88 Y53-6077-1B1 (03/17)
