Can not start the engine difficult to start the seven reasons

In all normal circumstances the engine , the starter or the battery is faulty will be difficult to start the engine , can not even start . If this happens, we must first understand the starter motor and the battery usage so largely determine the fault location . If the battery has been used for more than one year should focus on checking the technical condition ; If the battery usage time is shorter, and start the machine for a long time did not repair , you should check up from the starter . And then start the fault phenomena analysis and processing .

1 , only start to hear the starter solenoid switch "giggle " sound, or first startup machine driven slowly turn the crankshaft several times, followed by start solenoid switch " giggle" sound, but do not turn the crankshaft . This phenomenon is generally belong battery " off grid " fault.

2 , temporary parking every time start, but parking is a long time , or the next day when launched will only make the crankshaft turn about . This phenomenon is a serious battery self-discharge , the plates, separators serious aging , indicating that the battery is close to retirement .

3 , start the machine suddenly starts turning weakness , accompanied by burning rubber smell or smoke coming out at the battery , mostly very piles, piles clip very poor contact heat burning .

4, if the startup -drive gear with the engine flywheel ring gear idling issue impact sound, for two reasons : First, the flywheel ring gear meshing cut surface deformation ; Second, the starter drive gear and flywheel ring gap is too big . Both can not be engaged , the engine will not start.

5 , a power switch is turned on and the starter drive gear meshing with the flywheel ring gear rotation . This failure , one starter solenoid switch holding coil connected to the wrong terminal on the power supply ; Second, the key switch on the three lines are wrong , judging method is : Key in "0 " position, the starter drive gear does not turn, in the "2 " position to start the motor drive gear rotates together with the flywheel ring gear .

6, the start switch is turned to the start position the engine can not be started , and no other phenomena . This failure , one key switch turned on due to wear without starting circuit ; Second, the starter relay is not turned on the starter solenoid switch circuit ; Third, the power switch is not connected to the main circuit .

7 , starting with only a slight "click " is heard, no further response, which is due to start relay card . Then just click on the electromagnet tail , forcing the solenoid forward, then will start circuit switched , so that the engine starts.
