While a few of you are having a problem with not enough spark, I am having the opposite problem.  I put the battery in tonight and started to run through systems checks.  The test modes in the EC2 are really nice features. Injectors and new injector disable switches seem to be working fine.  The problem is with the coils...  Way too much spark if that is possible.

 

I planned to test the LS1 coils 1 at a time but quickly found that 2 of the coils are arcing past the rubber boots of the spark plug wire, one more than the other.  I thought maybe the rubber had gotten old (though not that old) so I swapped in one of the wires that was not leaking - but that did not solve the problem.  I took all the wires off entirely, and sparks were flying out of the socket and arcing across several inches to reach the control harness for the coil.  The other coils were not doing that, though they were making normal sparks when connected to a spark plug.

 

I assume this is not normal.  Does anyone know of a condition that would make the coil voltage go through the roof like that?  The coils did get a good dousing of coolant 1.5 years ago.  Also, I notice that the coils are drawing 3 amps even when not running.  Time for some new coils?
