一辆日本三菱 T850型载重汽车开左右转向信号灯均正常闪光,开报警闪光信号灯时,右转向信号灯及右转向指示灯均闪烁发光,而左转向信号灯及左转向指示灯却不闪烁发光。经观察分析,该车在转向及报警信号灯电路上采用了(MC843790,066500—1430)(25.6V,85°/m)集成电路电子闪光器,它的线路联接与一般车型的线路不尽相同(图1)。其电源(24V)通过电路控制箱内的第12档15A片状熔断器(RD_(12))后,接至闪光器插头引脚1(引脚功能如图2所示)。
When a Japanese Mitsubishi T850 truck turns on the left and right turn signal lights normally flashing, when turning on the alarm flashing light, the right turn signal light and the right turn light both flash and the left turn signal light and the left turn light do not flash. The observation and analysis, the car used in the steering and alarm signal circuit (MC843790, 066500-1430) (25.6V, 85 ° / m) integrated circuit electronic flash, the line connection and the general model of the line is not the same figure 1). The power supply (24V) is connected to the flash pin 1 of the flash connector (pin function shown in Figure 2) after passing through the 12th stage 15A chip fuse (RD_ (12)) in the circuit control box.
