一台广西产桂花牌多功能小型拖拉机,新机买来投入运输作业,一个星期后就经常发生保险片被烧坏的故障,其原因是充电电流过大。初步确诊故障可能出在电子调节器上。于是机手换上一只新的机械式调节器,当发动机处于中等转速以上时,充电电流仍大于15安培。后经调松调节器的拉力弹簧,将充电电流调到15安培,正常工作一个星期后,又出现因充电电流过大烧坏保险片的 A Guangxi-based Guihua brand multi-function small tractor, bought a new machine put into transport operations, a week after the fuse has often been burned failure, the reason is that the charging current is too large. The initial diagnosis of failure may be in the electronic regulator. So the hand replaced with a new mechanical regulator, when the engine is at medium speed above the charging current is still greater than 15 amps. After adjusting the regulator by the tension spring, the charge current transferred to 15 ampere, after a week of normal work, but also because the charging current is too large burn fuse
