絕對不要拿著plugwire看星星(未接地的迴路),讓火星塞就這樣拿在手上~空打點火
open fire指斷路點火,例如把火星塞接頭拔起來(火星塞還在車上)發動引擎,也是未接地的迴路
上部的火星塞~兩個筆型coils的電阻
Primary 初級線圈 0.87 ohm
Secondary次級線圈 not measurable 1 KOHM(new)

正確的火星塞跳火測試 使用工具
OK Spark 100072 Spark Plug Sensor Tester 。
靠著各汽缸的火星塞高壓電纜線接頭測試~燈亮才正常

我花
錢買的如下
錯誤不正確的或者一般(不適用BMW)的檢查方式,直接幹掉BMW零件,還有例如 HALL SENSOR 及Motronic~CLYMER書:Page 381第7.說的
改裝Coil 很醜就是了~Coil Sticks no more!

拔掉下面的plug wire,引擎就熄火,恭喜發財 ! 上面的Stick Coils壞了

towerworker has the right procedure, but from the description, the wrong wire. I know why. Wayne, you need to turn off your beeper and company cellphone, knock off that overtime and get some rest! Even your icon and screen name are about work! 本段都是廢話
OK, the test . . . The bottom plugs use a single spark dual coil. One coil with 2 secondaries that fire both lower plugs every turn of the crankshaft. Pulling off a secondary plug wire could give you a really big 40,000 Volt shock!! Besides that, open firing it's dual coil forces the generated spark to make a new path and that can damage the coil. Also, when you pull off one secondary wire on the lower plug, the other lower plug may not fire either. The wire to pull off while the bike is running is the thin primary coil power wire on the upper plug's computer coil. If the idle deteriorates, you have the bad part.
FYI, Wayne is a good man & I consider him a friend. He's just overworked.
by jcridge » Tue Oct 06, 2009 12:45 pm如下說
I would think that if you pulled the electrical connection off the stick coil while the engine was running and the idle got worse, it would indicate that the coil and plug were firing correctly. If you removed the electrical connection and nothing happened, that would indicate a bad coil and or plug. Ja...???也就是說~拔掉上面的Stick Coils引擎就惡化表示點火正常,反之如果拔掉上面的Stick Coils引擎正常就表示點火異常
To update, I did experience misfire at highway speed this morning in very heavy fog. Started about 20 miles into the trip and when I got off the highway it was fine. Seems like light throttle and moisture are the key here ( low voltage combined with lean稀A/F misfire) 看似因大霧的霧氣和低油門造成不點火,(低伏特和稀的空油比)

jcridge,
Yes, that is correct. On a very rare occasion, even Cyclerob can make a boo-boo. If the idle does NOT deteriorate惡化 when the primary is disconnected, then it was already not working. 是的,拔掉上面的Stick Coils引擎怠速沒有惡化,表示上面的Stick Coils已經沒有功能了
FYI, Cyclerob is wonderful resource of knowledge and experience. We are all very lucky to have him looking over our virtual shoulders. Maybe we can chalk that one up to being over-retired.
上面的例子
一般的檢查方式,不適用BMW,一般的汽機車維修高手(含重機),反而在檢查的時候,就直接幹掉BMW零件 !
我不懂,所以我謙卑(用功),因而得救,感謝主耶穌 !
