左后刹车灯不亮

[Damiyo]

shrink tubing 看着比电工胶布强多了

Is the light on the lid of the truck? If so, check where the wires flex when the truck opens and closes. There should be a wire loom.
Pull the broken wire out, solder a new wire on (or use a crimp connector) run the new wire trough. Make sure the solder point is not the same place the old wire broke. Off set it a bit.
Put in some lubricant in the loom so the wire will not rub against each other dry.

If you do not replace it with new wire and simply crimp it, there is a good chance it is going to break at the same place soon.

换过了，还是左边不亮右边亮，只能说明是电路问题了？这下麻烦了，修电路不知道要多少钱…

哥，修电的东西要测电，眼睛看不出哪里断电。

Once LZ get to the wire loom, just pull on each wire. The broken one will come out. Most likely the entire wire is broken not just the copper inside.
I recently had to replace two wires broken this way on a 13 year old BMW.

修电的东西要依靠万用表，不能靠手拽。很好奇你用这种方法对付宝马，宝马是有名的“聪明”车，我是不敢踫的。

你这方法和《通讯基本靠吼》有的一拚。

你大学读什么专业？

其实电路不复杂，读一下线路图，回忆(复习)一下初中(二？)的串联，并联电路。heibor freight买个$6万用表,量一下故障处电压，保险丝处电压，等等，总能找到电断在哪里。

找到电线断处，米国有shrink tubing, 重连电线即可。

Happy fixing by you self.

测个屁。修车看经验，这就是灯泡烧了。不放心可以拆下来对着灯光看看灯丝是不是断了。十之八九就是断了。然后拿着坏的，去买个一样的好的就行了。

读帖不仔细，楼主已用好灯泡换过，还是不亮。

是线路问题。

好灯泡接触不良呗。那两条腿，是两个破铁丝。弄个砂纸磨两下，用手拨起来一点增加对插座的弹力。然后再插。

知道哪里不好，修起来都简单。这个问题要用万围表量过去，找到故障点。用test light 也可以。

转向灯好像没有刹车灯容易烧 据说转向灯烧了 哒哒声频率会变高提醒

不用据说，马路上经常见到转向灯狂闪的，一看另一头的转向灭的

The Circuit Concept

I have found a transistor-based flasher including a relay, online

Physically, the circuit oscillates when a Load is connected across the pin "C" of the relay and earth. If the load is less than 100 Ohms the oscillation is significantly fast. And if the load is say about 1K the frequency is normal.

日本车根本不检测这个，只有欧洲车还实心眼测电流，经常能看到只有一个刹车灯亮的丰田，可靠性就是这么来的

连我的2014 ram 1500都有这功能，大灯灭了就报警

[agnis]

试试这个，把交接处打开看看有没有断线

美国车介于欧日之间，比日车要良心多了，但是还是不如欧系sensor多，你的RAM1500就没有润滑油液位传感器，时不时查一下液位很重要

机油高度传感器？我都是看机油压力数值。我开车时仪表盘上显示必备的几样数据，变速器油温，机油油温，机油压力，发动机水温

等到油压太低已经有点晚了，我开的也是RAM1500，建议装一个oil catch can，我都是自己换liquimoly机油，现在五年半，九万英里，状态很好

研究过这个，没整。我都用mobile 1。这车抗造，快14万了还好好的，卖了。另外oil catch can有可能void extended warranty

卖了多少刀？

1万2千5，给了dealer
