What is the cause of the difficulty in starting up our vehicle?
In this case, the small suction truck teaches you a few steps to check the cause of the starting fault of the suction truck:
Loose or off the cord of the starter, the switch or adsorption switch failed.
The battery has no electricity or weak power, so there is a fault that the starter cannot turn or turns slowly.
Coil or armature coil short circuit and break.
Wear on the brush or the brush surface is not correct, the spring is weak, so that the rectifier contact is not good.
Pollution damage of the rectifier, mica protruding, resulting in poor contact between the brush and the rectifier.
