Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 2007testing for spark on 1998 dodge stratus 2.5 v6?
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 The engine cranking speed is slow; there is a very noticeable time between sparks. Even at idle speed the spark does not appear continuous. > 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  SignatureMike Walsh > 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 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 :-) >> 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 [quoted text clipped - 5 lines] > divided by 12.

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. > Still wondering how the ceiling fan fits in though... I wouldn't worry about it.

Steve Austin _______________________________________________________ Yup, I pooched the math. aarcuda69062 _______________________________________________________ Explain how you're wrong? .. it's a distributor-equipped V6 which fires fire one plug wire once every twelve crank revolutions. dividing crank revolutions by 12 sounds good to me. Comboverfish _______________________________________________________ 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.

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. > > Explain how you're wrong?

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 |
