Breakdown phenomenon: Wild car of outstanding Luo Yue uses handkerchief of a 3 water chestnut many a little bit technology of electronic fuel eject, equipment is automatic transmission, when ignition switch is shut, it is normal that left right-hand rotation twinkles to the lamp, it is normal also that lash-up emergency warning lamp twinkles. But after be being started when engine, put through again turn to the lamp or emergency warning lamp, left change the lamp to Chang Liang and do not twinkle.
Breakdown analysis: Begin to suspect breakdown and alternator neutral nod jumper to concern, the engine that start, unplug line of the magnetic field on next alternators and neutral site connect the outlet of the line, but breakdown still exists, demonstrative breakdown is absent here. Had inserted this outlet afresh, farther observation starts engine room and dashboard below appear wiring harness, whether does the examination have wiring harness short circuit, worn-out appearance, the result appears wiring harness all good, did not discover damaged phenomenon. Tear open next dashboard examinations to whether have the place with short circuit of circuitry of turn light indicator again later, express the diode that go up and component of other electric equipment to whether have the place of attaint with avometer measuring instrument, the result did not discover unusual situation.
Suspect breakdown and chassis circuitry are concerned then. Unplug chassis circuitry connector right now engine is locomotive condition , engine instantly flameout, and breakdown phenomenon also disappears subsequently. Find out from plug left hind the front line that turns to the lamp, good connector is inserted afresh after pulling out this front line alone from plug, the engine that start, engine movement is normal, breakdown disappears. Apparent, breakdown is left hind the place that turns to lamp electrical wiring and other electrical wiring to have short circuit. Shut ignition switch, make engine flameout, unplug next chassis circuitry connector, ravel floor layering, pull chassis wiring harness, chased paragraph of microscope backward once upon a time, the result discovers wiring harness is in point of crural footplate turning to have wear away traumatic, left hind because of,change lights to line and another front line worn-out and be together repeatedly. The output front line that decides via the examination this front line is fuel pump relay (this car is) of dynamoelectric gasoline pump. Include good tatty wire with insulating tape, make left hind change lights line to restoration, insert good connector afresh, the engine that start, breakdown eliminates instantly.
