Common troubleshooting methods for generator voltage regulators.
1 ． First check the oil level, the generator voltage regulators is normal when you can remove the oil alarm installation wiring, if you can start the engine, clarify the oil level alarm installation damage, can be removed to check or perhaps replace.
2 ． Not press the incineration switch can start the engine, clarify the switch short circuit. Can remove the incineration switch for inspection or replacement.
3 ． If the spark plug magnet is cracked, the middle electrode is damaged by erosion, the spark plug should be replaced.
4 ． Spark plug is too dirty, can be cleaned with gasoline, and then the electrode gap adjustment to 0 . 6mm and then dry it from new use.
5 ． Check the low-voltage coil, Cummins parts charging coil resistance value can be in its limits, or reflect on its peak voltage can be normal to check the check, or change the relevant coil or electronic incinerator as a whole.
6 ． High-voltage wire and spark plug joints such as articulation Cummins speed board can be replaced with a new joint, when the high-voltage wire moisture leakage, can be removed to clean, and then dried, the disposal is still invalid, should be replaced with a new high-voltage wire.
7 ． Assuming that the incineration system is normal, you should reflect on whether the oil circuit can be unblocked, whether the gasoline in the tank can be mixed with water. Attention: reflect on the oil circuit not only to reflect on whether the oil pipe can be unblocked, but also to reflect on whether the carburetor can accumulate impurities in the generator controller blocked the main volume hole Disposal method: clean the carburetor with gasoline.
8 ． Reflect on the fuel tank can have gasoline, and then carefully check whether the oil switch can be opened, and then dredge the tank vent to let the tank and the atmosphere connected, constitute a pressure difference.
9 ． Remove the carburetor and fuel pipe pipe, slightly suck it with the mouth, there should be fuel out; if there is no fuel out, you can remove the oil cup filter, oil filter network, and dredge the articulation tube with compressed air.
10 ． If the oil pipe out of oil, you can reflect on the carburetor oil intake; use a screwdriver to loosen the carburetor oil release screw, such as no oil, can be the oil needle valve stuck. Should remove the carburetor, check whether the oil needle valve can move, whether the float chamber can have water without dirt, whether the main jet can be blocked, or perhaps a thorough cleaning of the carburetor. 11. Reflect on the pressure in the cylinder, the normal normal 6 a 7 105pa, cylinder pressure is too low, usually a local blockage is not tight, there is a gas leak scene. No pressure gauge, you can experience: one is to block the spark plug hole with your fingers, start to sense the airflow to the outside, clarify the pressure enough. The second is to plug the spark plug hole with a small cloth ball (no air leakage). When starting. Can hear the gas rush out when the bright sound, clarify the pressure is normal. Otherwise, the cylinder tightening pressure is low. Also a, the price of the bender to reflect on the connection surface (cylinder head and box connection surface, spark plugs and cylinder head combination connection surface) can be tight, Cummins actuator can miss the head gasket, etc. b, piston ring wear severe, need to replace the piston ring. c, valve seizure scene, where the purging of carbon on the valve, etc..
