第二十章电气设备第一节蓄电池1.车上检修本车采用的蓄电池为免维护蓄电池，如图20-1。
在检测蓄电池时可以通过安装在蓄电池上能够显示荷电状况的密度计来判断其状态，如图20-2。
图20-1图20-2（1）当电量超过65%时蓄电池正常，从密度计观察孔可以观察到绿色。
（2）当电量少于65%需要充电，从密度计观察孔可以观察到黑色。
（3）当从密度计观察孔观察到透明色时，表明蓄电池已报废，需要更换。
2.充电（1）若装在车上对蓄电池充电时，应拆下蓄电池连接线，以防损伤电气元件。
（2）对蓄电池充电的正常电流应该是该蓄电池容量的1/10左右。
因时间关系等原因需要进行快速充电时，充电电流绝对不要超过蓄电池以安培（A）表示的容量。
注意：在充电时不要靠近任何火源，否则可能产生爆炸。
在充电时不要在旁边进行易产生火花的作业。
3.蓄电池的试验方法试验顺序见图20-3。
蓄电池正常图20-3负载试验速率见表20-1。
表20-1第二节组合开关1.拆卸与安装拆卸顺序见图20-4：图20-41-组合开关罩2-组合开关上罩3-照明开关4-刮水器、洗涤器开关2.检查（1）照明开关的导通检查（见图20-5）图20-5（2）组合开关（开关本体部）导通检查（见图20-6）①卸下照明开关及刮水器、洗涤器开关。
②在组合开关本体各接头间，检查相同端子号（3~11）之间的导通关系。
第三节点火开关1.拆卸与安装拆卸步骤见图20-7：图20-71-驾驶员侧下罩2-方向盘3-组合开关上罩4-组合开关下罩5-组合开关6-转向锁芯7-点火开关拆卸操作要领。
点火开关锁的拆卸：①将钥匙插入转向锁芯，转到“ACC”位置。
②用十字槽螺刀或类似工具，把转向锁芯锁定销向里推，然后把转向锁芯往自己方向拉（见图20-8）。
图20-82.检查点火开关导通的检查（见图20-9）：图20-9①拆下组合开关下罩和组合开关上罩。
②从点火开关拆下线束插接件。
③操作开关，检查各端子之间的导通状况。

路宝完全维修手册发动机概述本发动机为四缸直列水冷四冲程发动机，双顶置凸轮轴，气门机构成"V"型排列，16气门(单缸两个进气门，两个排气门).气门由曲轴通过同步链驱动凸轮轴分别开启关闭。
本发动机采用联合汽车电子有限公司匹配的多点控制喷射系统，大大降低了尾气中的有害成分含量，是完全适应新配方法规要求的绿色环保动力。
此发动机采用多点燃油喷射，包括检测发动机工况的传感器，发动机的电子控制单元(ECU)根据这些传感器发出的信号控制该系统;各执行器在ECU的控制下工作。
ECU具有燃油喷射控制，怠速控制等功能，并且，ECU还具有发生故障简化故障排除的若干故障诊断方式。

第九章发动机电气系统第一节起动系统1.概述如果点火开关被转到“START”位置，则电流就流入电磁开关内的线圈而吸引铁心，当铁心被吸引时，连接到铁心的杆就动作使起动机离合器接合。
另一方面，被吸引的铁心将电磁开关接通，使B端与M端导通。
这时电流流通使起动机啮合。
当在发动机起动后点火开关返回到“ON”位置时，起动机离合器从齿圈脱开。
在小齿轮与电枢轴之间设有一个超速离合器，用于防止起动机损坏。
系统如图9-1。
图9-1起动机规格见表9-1。
项目规格型式用行星齿轮减速驱动额定输出功率（kw/V） 1.2/12小齿轮齿数（个）8检修规格见表9-2。
项目标准值极限值小齿轮间隙/mm0.65~2.0—换向器外径/mm32.031.4换向器偏心率/mm—0.05换向器切口/mm0.50.22.起动装置的安装拆卸拆卸顺序见图9-2：图9-21-进气歧管支架 2-起动机插接件 3-起动机3.检查1）小齿轮间隙的调整（见图9-3）图9-3（1）从电磁开关的M端子脱开励磁线圈配线。
（2）将12V蓄电池连接在S端子与M端子之间。
（3）将开关置于“ON”，小齿轮应伸出。
注意：这个试验应迅速完成（10s以内），以免线圈烧坏。
（4）用间隙规检查小齿轮至限位块的间隙（小齿轮间隙）（见图9-4）。
小齿轮间隙：0.5-2.0mm图9-4（5）如果小齿轮间隙不在规定范围内，用增加电磁开关与前盖间的垫片的方法予以调整（见图9-5）。
图9-52）电磁开关的吸入试验（见图9-6）图9-6（1）从电磁开关的M端子脱开励磁线圈配线。
（2）将12V蓄电池连接在S端子与M端子之间。
注意：这个试验应迅速完成（10s以内），以免线圈烧坏。
（3）如果小齿轮伸出，然后又缩进则表示线圈正常。
否则，应更换电磁开关。
3）电磁开关的保持试验（见图9-7）图9-7（1）从电磁开关的M端子脱开励磁线圈配线。
（2）将12蓄电池连接在S端子与车体之间。
注意：这个试验应迅速完成（10s以内），以免线圈烧坏。
