请教黑哥：点火问题

[buddy]

NISSAN STANZA

一个多星期前发动车时发现车内控制盘上的 Charge warning light 亮. 手册上说可能是充电系统的问题. 应检查 alternator belt. 我这一个多星期没动车. 今天发动车时, 一点反应都没有了. 电池肯定没问题. 因为所有灯都是亮的. 而且我还让朋友把他的车的电池也接到我车的电池上, 然后发动他的车(Toyota Camry)试了一下, 也不行, 一点声音都没有. 是不是哪根导线断了?

因为发动不了, 连车行都去不了, 请黑哥一定要帮忙解决一下. 谢谢了.

1,确定借电时,接线一定要接的可靠,可能的话,先把电池充电5分钟,之后再启动.
2,有电压表的话,量一下电压,不低于12伏
3,把档位手柄放N位,再启动试一下

个人感觉应该可以BOOST起来.

我量了一下电压, 9.5 伏. 但问题是拧钥匙时, 什么反应都没有. 电压低可能打不着火, 但不会一点反应都没有吧?

You battery must have problem or the generator circuit has problem. The standard voltage is 12V, it could be 13.6V when it is fully charged. A battery in good status should be 12.5-13V in normal daily running.

When engine starting, it sucks ~100 A current. I don't think a 9.5V battery can provide a fraction of 100A current. So 一点反应都没有.

Check the fuse first. Lamps use different fuse with the engine starting. Working lamp doenes't mean engine fuse is ok. With a failure engine fuse, you can neither start the engine nor charge the battery.

If you do find problem on fuse, you may have to find a charger to charge the battery before starting the engine, or ask a friend to boost you car to get the battery charged.
