Thumbs up if anyone gets the sealab 2020 reference.

I wired up my LS2 coils. They have 4 pins: hot, ground, signal ground, signal.

To test out the wiring I lay a plug on the windshield. I cranked the motor and it sparked! But, the body of the plug was touching the windshield wiper. Both the spark plug point sparked, and so did some other spot on the wiper a distance away. Woops

I moved the plug away from the wiper so it was only laying on , and tried cranking again. No spark.

?????

What's going on?

Pretty sure you were grounding the spark plug to your wiper, you need some sort of ground for the plug otherwise it will not fire...

Try holding on to it next time...you'll know if you did it right or not.


Yeah man, seriously, the plug needs to be grounded. I've thought about upgrading from the OE COPS to the LSx ones...but I'll get around to it eventually.

OK I don't understand this ****.

With my stock 01+ coils, I could lay the COP on the windshield, stick a plug in, and it would spark away. WTF? Why won't these?

Do you understand how a spark plug even works? How about a light switch?

Barely.

So why would my COP plug spark when the plug was not touching anything?

apparently, it WAS touching something.

To make a spark, you need two connections - a positive and a negative

Your spark plug wire is the first connection, electricity travels through the wire, through the center of the plug, to the electrode at the end of the plug

The second connection is the ground of the spark plug. The metal jacket on the "threads" of the spark plug is this second connection, screwing the spark plug into the cylinder grounds the plug to the engine block, and now you can have spark.

Trying to spark with only one end of the spark plug is like putting your tongue on only one electrode of a 9v battery and expecting to get shocked. Without bridging both electrodes with your tongue, you wont feel anything.

Thank you for the explanation. I must have had the cop lying on the valve cover not the windshield. I fail. **** me.

A recent article ranked the US 35th in Math and 29th in Science worldwide. But the kids have good self esteem and plenty of condoms. In fact, we lead the world in condoms. So we've got that going for us...

FWIW I actually was taking calculus in 5th grade at Johns Hopkins but then proceeded to fail high school. Does that explain anything?

So you developed a boost leak, eh?

Check this out…my Dad went into the Military after partial HS. They put him in tech stuff - communications / encrypting when they noticed that he was bright. He gets out…then finishes his HS degree at night while working as a plumber…age 28. Then he went to MIT studying Engineering followed by Harvard for his MBA (became class President) and later studies. Once he decided to learn…the rest was just details.

Clearly this indulgence in math has led to a severe lack of deductive reasoning.

Federal Spending Under the Elementary and Secondary Education Act







My datalogs conclude we should throw more money on the problem.

My niece and nephew out in Glendale, CA go to a Catholic private school…with no crime and great academics. The per head cost is 1/4 (update…less per my sister) of the area public schools. It's not about the money as far as the student education goes. And it's about the parents too.

Some areas of the country have tenured teachers in their 40s that retire on 90% of the their first teaching job's final year pay. While moving to a new school to continue at higher pay. If they marry another teacher, some wind up with a 400k income and a 9 month year with low stress. Not bad considering you can't get fired and education results don't matter. Not to mention getting a teaching degree is not all that difficult.

I doubt this is happening elsewhere in the world.

Well judging by this thread there was apparently one too few condom used.

This might have worked better:

I, for one, am counting on the masses of people without diplomas, and hope to use them one day when I figure out what kind of business I want to start.

If everyone had a college degree, who would work in our unskilled industries making $4.50/hr?...


....oh wait. Government has made it illegal to hire workers to unskilled jobs while paying them what they are worth - effectively making it illegal for HS dropouts to find work.

I saw on TV, Obama was charging the American business owner to find ways to hire people. Obama, why don't YOU find ways to make it profitable for the American business owner to hire people. In a recession, wage rates naturally want to fall, but you've made it illegal to pay someone for their contributions in current dollars. As a result, people like Faeflora can't find a job...

Now now. At least my miata is running

With the gentle guidance of MT.net I figured out the problem and started my up running with sequential ignition.
