B7648-1115100 Fuel Stop Solenoid

  Loaders are widely used in construction and road construction, from the purchase of new machines to scrapping, but also have their own service life, and according to the working environment, operating habits, different degrees of damage, and the quality of the machine itself, its working life and service life are also different. Although the service life is different, it is certain that as the service life increases, the frequency of loader failures will also increase. As the years increase, the common failure of the loader is the problem that the engine cannot ignite, but what we are talking about today is not the ignition failure, but the fault handling of the loader that cannot be turned off.

  First, if the engine cannot be turned off, first look at whether the flameout gear of the ignition switch is damaged, check the extinguishing switch components, check the power on, and replace the corresponding components.

  Second, the fuse is broken: there are two fuses next to the flameout relay, one is a 5A fuse and the other is a 30A fuse, check whether the fuse is broken, replace the fuse and find out the reason for the fuse break. Shandong loader

  Third, the electrical plug-in is loose: the loader working environment is not good, the vibration may make the electrical plug-in fall off, resulting in the inability to turn off, we must check whether there are loose components, and do a good job of fastening.

  Fourth, the flame-out relay is bad: 327A is measured, short connection 101 line and 327 wire, can be extinguished, then the relay is bad and needs to be replaced.

  Fifth, the gap problem of the flame-out Solenoid valve: the gap of the flame-out Solenoid Valve on and off the oil circuit is unreasonable, resulting in the solenoid valve is normal but the loader cannot be operated to stall, and the gap needs to be readjusted to solve it.
