when using a spark tester and turning the engine over,should there be continuous spark at the gap of tester? when i do it on my #2 plug i can make a one count between sparks. is this normal? i thought it spun so fast that it should almost continuous? i also don't think it's real blue in color. thanks Randy
testing for spark on 1998 dodge stratus 2.5 v6?

At one plug wire, the spark frequency will be cranking RPM divided by 12. At 200 RPM cranking, you'd see 17 sparks per minute or one every 3 seconds or so.
thanks for the info Randy :-)

do me a favor........count to 3......then think about that remark as you watch yer ceiling fan go around in cirlces.........

lmao...........fk it............takes another toke....... mmmmmmm.........good stuff~ ~:~
Still haven't figured out how a 6 cylinder 4 stroke engine operates, eh.
Check your shorts first.
What the f*ck do my ceiling fan(s) have to do with this?

cuda's math sounds okay to me, assuming it is a 6-cylinder engine. What different result does your calculation show?
Rodan.
Every plug fires on every second revolution. Cranking RPM divided by 2.
If it's DIS every plug fires on every revolution.
Yup, I pooched the math.
Still wondering how the ceiling fan fits in though...
Explain how you're wrong? You said *at one plug wire*... this is a distributor-equipped V6 which would fire *one plug wire* once every twelve crank revolutions. You said *divide crank revolutions by 12*.
Sounds good to me. We may be the only ones accounting for the type of ignition system used on the OP's car.
I wouldn't worry about it.

I pooched it too. It doesn't matter how many cylinders the engine has. The spark rate for a single wire is:
200 Rev/Min x 1 Spark/2 Rev = 100 Sparks/Min = 1.667 Sparks/Sec. This inverts to 0.6 Seconds per Spark.Rodan.
Think about it...it's a four-stroke engine, right? In a four-stroke, every cylinder fires (has a compression stoke) every other crank revolution (half the cylinders fire on each crank rev). So for 1000 rpm, each one will fire 500 times/minute.
Or...the distributor turns at half the crankshaft speed and each cylinder (plug wire) fires once on each distributor rev...same result.
I thought about it after posting. Too much drinking of Koolaid. Better now. Math skills rising again.
Thanks!

make sure you have it on "slow" speed........while counting to
3..........high speed.......is closer to "eng run" RPM's.

YOU'RE.......still wondering because yer freek'n brain can't configure the concept of "like" systems.....and.....i'm reeeeely not sure at this point that if you even own a ceiling fan...... if you're capable of counting to 3. . . and.......how bout take some terlit paper and scroll back up and wipe thatshitoff that you stunk up the joint with......

~:~ marsh ~takes a toke......mmmmm........good stuff......~ ~:~
"like systems?" How is an automobile engine "like" an electric motor?
Is owning a ceiling fan some measure of intelligence?

Shouldn't you be tying knots in brake lines or something?
Hi, Rodan, this math is getting fun, to the extent some of us (me included) tend to cloud our own knowledge. Honestly, at first I was tempted to ask him how many cylinders, as I had not seen the 2.5 v-6 in the op's subject line--that before I realized it made no difference. What different result would we get if we assumed it was a 4-cylinder?:) How about an
8-cylinder?:) Just tho't it humorous that you and I both were victimized by this same slip-up--- hope you see no offense! sdlomi2======= ======= aarcuda wrote: In article
