Subject: [FlyRotary] LS1 Coil Connector

Hey you guys, with all this chatter you could have built your own.  This was

a good job to give my wife.  I taught her to solder and she had them done an

hour later on one of those rare evenings she came to help.  I poured in a

little resin to fill the space, and later topped it off with some RTV to

soften the transition.  Cost: $0.

I'll take that as a high complement Dave.  Yes, a good solder joint with proper strain relief is more reliable than any connector and cheaper to boot.  Good idea on the RTV topping, I didn't think of that!

True, but not quite as easy to remove the coil(s).

 The solution to that is to direct wire all the coils to a single connector (of your choice) so that the coils may be removed as a unit.  That is what I plan to do on my 20B - RV-8 and the 13B - RV-4 when I update it for the LS-1 coils.  Yes, this may complicate the replacement of a coil if it should be necessary, but I know of ZERO actual coil failures.  (not counting the Mazda ballast resistor failures which would not require coil replacement anyway).  All other reported coil failures have turned out to be something else when the failure was actually determined.   Chime in if anyone knows of a failure I haven't heard about.

It appears that you have just moved the failure point upstream, but the connector (of your choice) is still there and open to possible failure.  Personally, I like the weather-tight seal of the GM connectors, and the ability to remove individual coils (possibly at some remote location), but not the cost.
