This van because air conditioning breakdown, undertake maintaining. Should fill snow to plant when the car that start, the key is started without reaction, can start again after, till air conditioning maintenance ends, car cannot be started thoroughly
The car enquires after advocate, car advocate reaction van is started constantly without reaction, await a little while, can start again.
Breakdown phenomenon: Van is started constantly without reaction, await a little while, can start again. (volmeter numerical value has the apparent voltage that start to drop)
The platoon checks train of thought:
- Check motor flyer to whether report arrives, (arrive without report) suspect the relay that start attaint, check discovery, have constant report take iron, but without report of the control that start (build the relay that start continuously car is started) eliminate to start relay to damage. Tear open a steering wheel remove theatrical makeup and costume to act the role of a box, whether does switch of measurement point fire damage (nondestructive is bad, report of the control that start is regular) when is ignition switch judged according to above normally start relay to start control report to cannot arrive, complete the action that start. Switch of fire of platoon check the number of comes the circuitry between the relay that start
Tear open a steering wheel remove theatrical makeup and costume to act the role of a box to measure ignition switch, road of electrical wiring of the foregone control that start is red, follow-up circuitry reachs point of outlet of car head circuitry, the key is started, the lamp tries to measure in plug place,
Discover light trying the light is faint, suspect plug contact is undesirable, after be being started for many times again, discover this line hair is very hot, try the key to be started for long in the archives that start again, discover this red line fume scorchs
Preliminary suspicion this circuitry takes iron, consult insurance box is sure without ignition switch (very without language) , continue follow-up red line, discovery starts line of relay fine door to be black red, judge switch of possible course neutral from this, continue to discharge Cha Zaibo near box, discovery one red the one line of black Gong Xiangjiao scorchs with build go up with crossbeam, removed its the package is nice, start again, it is normal that car is started.
Scorch its circuit changes, add one 20a insurance.
This truck van is started constantly without reaction, await a little while, can start again, the line after its block switch because of take out sky formerly was not wrapped good, electrical wiring of the control that start takes iron, in shake next shaking, till build iron adhesion to be on crossbeam, cannot start thoroughly.
Why to see neutral switch directly? Because do not have,think of!
