spent two hours at the boat last night with my friend the mechanic..... and what i accomplished was i learned some new tricks for testing continuity...i learned how to increase voltage by increasing distance....i learned lots about my carb ... i learned my engines will run all day on 5 cylinders....did not however learn what was wrong.....go back today and switch modules in an effort to eliminate that.....take the module from the good engine(starboard) and put it in the bad running one.(port)...as im putting the new module (which i put in the bad running engine (port) when it died completely)in the good running engine i notice a very small amount of un insulated ground wire showing where it looks like it got crushed by the retaining screw the first time around...wraped with tape and installed......both engines run again.........duh

I'm pretty interested in the increasing voltage by increasing distance thing, would be pretty useful in our transmission system.

my friend rattled off a formula....said it was couner intuative watch this...............stuck a phillips head screwdriver in the coil terminal on the distributor cap......took the wire and moved it closer and further from the screwdriver while the engine was running.......the spark got hotter as he moved it away (to a point)........went around the cap doing the same with each plug wire.....easy to see which were firing and how strong the spark was

I think the air gap increases the resistance so the coil builds a higher charge before it can discharge across the gap, hence higher voltage (or is it amps, I can never remember). I put Acce supercoils(the big yellow ones) on mine when they needed replacing and they work great. Ask me how I know they will raise the hair on your head!

Randall,
Is that because of the frasnoids being longer than the resonance descant factor and conversly profluent releasing of rolamite energy?
Or is it the opposite?

I think you nailed it, Andre!

Andre-

I know you're a diesel guy, but Mike's right, you nailed it. It'd only be the opposite if the test was performed while the boat was in the southern hemisphere...

like i said.......i dont have a clue why its true....but it is......BTW andre...i stole your line and use it all the time at volleyball....and im pretty sure the fraznoids have a lot to do with it

Andre, please send me a PM explaing both the mathamatical formula you used, and a explanation of what the fu*k your talkingabout.

You making it up for some woodcock, when your not jet setting?

Would the apperarance of more energy with larger gap between wire and screw driver still be applicable if you doubled the atmospheric pressure?
